To validate that 3CX is ready to listen for phones request open CMD command prompt and type: “Netsh interface ipv4 show join” You should see the joins on the network interface. If by masked you mean IP that is used on VPN or hided with proxy, simply you can’t. You may wonder what is this address used for. Enabling multicast routing initially does not route any data, due in fact that the default configuration leaves all router interfaces without multicast routing in their configuration. After IGMP join requests, when an IP datagram with destination IP address of a multicast group is sent, it gets forwarded to every node that has joined that multicast group. 255 IPv4 multicast range. I have a home exercise in which I have to answer if the address 195. A broadcast address is a special Internet Protocol (IP) address used to transmit messages and data packets to network systems. When an IGMP client connected to a switch port needs to receive multicast traffic from a specific group, it joins the group by sending an IGMP report (join request) to the network. Configure the multicast IP address and Send Audio Port (the same multicast address and port must be used for both the server and client programs), then specify which IP streaming interface is used to dial this connection, e. The reason is that you also need to block the mDNS multicast IP address – not just UDP port 5353 on your. Finally another technician changed the configuration of the Mikrotik and everything works perfectly since then. I have a home exercise in which I have to answer if the address 195. > > Now the problem clients cannot access to the cluster through *. Multicast Addresses. Pairing of IP address to a geographical location is the method we used to provide geolocation data. So the recommendation is to change both the address and the port. For network layer communications, a broadcast address may be an IP address. If you were to ping 224. So, the source's router (actually, the DR) encapsulates the multicast packets inside a unicast packet sent to the RP and tunnels the packet to the RP in this form. Address family not. In the example shown in Figure 1, a multicast source on the Marketing network with IP address 192. Observe the Destination address. mcastaddr Only one cluster seems to have the issue. 1 multicast IP address will configure its network card to listen to MAC address 01-00-5E-01-01-01. Check Multicast Source. IP multicast is most often used for streaming media, such as video and voice over IP (VOIP). In IPv6, ARP is not used but ICMPv6 is used to know mac-address by multicasting. The MAC address is listed as the WiFi MAC address. setBroadcast (true),. Answer: The subnet mask mentioned in above question (255. Check “Allow this package to transfered via multicast” at packages and your install image properties. Controlling the Default Multicast Address with -u. Not just Link-Local Addresses, but also a Solicited Node Multicast Address. You could use wireshark to catch some traffic and find devices that broadcast frequently, but I'm not sure how this will truly help you in the end. Verifying what data will be sent. RFC 2375 IPv6 Multicast Address Assignments July 1998 7. In the example shown in Figure 1, a multicast source on the Marketing network with IP address 192. Periodically, the multicast router sends general queries requesting multicast address listener information from systems on an attached networks. A multicast address enables a device to send a datagram to a specified set of hosts, known as a multicast group, in different subnetworks. ARPA domain is defined to look up a record given an IPv6 address. Check the Wireshark monitoring and find out where the streaming came from. This method is commonly refered to as a UDP rendezvous. 0 is from the router and broadcast to each LAN connected device. If address object is being used by multicast zone and multicast mode is not enabled globally and on interface, then follow the steps below to enable multicast mode: 1. If you want a QA cluster and a production cluster, the easiest config is to have the QA cluster be on a separate multicast address/port combination than the production cluster. These mac addresses are all start with a odd number as the first octet. You send from a regular IP address to a multicast address. Set up a new "capture filter" as such: Filter Name: Broadcast and Multicast. By default, Cluster Control Protocol (CCP) works in Multicast mode (for more details, refer to sk93306 - ATRG: ClusterXL R6x and R7x). I'll explain below exactly how to determine the multicast MAC address from the multicast IP as well as provide a few helpful websites. Java supports this with the help of an API called isMulticastAddress(). 255 is the range designated by IANA for local multicasting. traceroute ip in terminal of MAC or Linux. This document focuses on the basic configuration of PIM and does not discuss any PIM features in detail. 15, and virtal IP address for clients to access is > *. I know what my IP address is and tried using that, but it didn't work. I need this configuration to set up weblogic in cluster mode. The multicast addresses are class D IP addresses ranging from 224. To give you the knowledge you need the instant it becomes available, these articles may be presented in a raw and unedited form. VideoLan media player (VLC) is an incredibly versatile media player available for Windows, Linux and other *Nix clones. Generally, it is not recommended to broadcast log files to all machines as UDP receiving. Not all multicast addresses are equal. The reason is that you also need to block the mDNS multicast IP address – not just UDP port 5353 on your. This is the address assigned to "all systems on this subnet. The server can allocate IP using client MAC address, using address pool and using automatic method. A multicast frame contains the unique multicast MAC address of an application, protocol, or data stream. The multicast's source doesn't need to join its group, nor does the source know who and where its receivers are. 1 and we see pings ggo out but on SRX ( and EX 4200) I see this is not the case. Run the following commands on each cluster member to get the list of the Multicast MAC addresses that were associated with Cluster Virtual interfaces:. Method 1 - Using 'ifconfig' Command:. 1 multicast IP address will configure its network card to listen to MAC address 01-00-5E-01-01-01. Figure 3-16. The multicast router must find multicast sources on the network, send out copies of packets on several interfaces, prevent routing loops, connect interested destinations with the proper source, and keep the flow of unwanted packets to a minimum. There are three general types of IPv6 addresses: unicast, multicast, and anycast. NPM currently provides Multicast monitoring. Using Multicast with Dante Controller | Audinate. 0/4, but some addresses are reserved for special purposes (e. You send from a regular IP address to a multicast address. Then it looks in its MAC address table to see it it has an interface for the destination address. IP multicast provides a third possibility: allowing a host to send packets to a subset of all hosts as a group transmission. 03 User's Guide on page 162. One advantage of the Multicast modus is that all nodes in the cluster keep its original MAC address. The IP address used in the example was 203. Expand Internet Protocol Version 4 to view IPv4 details. Actually you may find this interesting. It's been a while but here's a quick post on how to calculate a multicast MAC address from an IP address. The network administrator can also open the specified port in the firewall. Question 1 - Find the network address and the directed broadcast address of subnetted Class B IPv4 address 172. Hi, For some experimental purpose, I like to change the mac address of an interface to multicast mac address. 94, you should probably replace that with the IP address which you have on eth0 or similar. 151″ & IPADDR2=”192. While in the past multicast. Distance Vector Multicast protocol is one of them. By default, with multicast-enabled network cards, the NIC will listen to only 224. Check Multicast Network. y) instead of to use standard multicast addresses (224. 250 on port 1900 via the UDP protocol. An IPv6 packet sent to a multicast address is delivered to all interfaces identified by the multicast address. The reason is that you also need to block the mDNS multicast IP address – not just UDP port 5353 on your. Internet Gateway: The Amazon VPC side of a connection to the public Internet. The attached screen dump shows some of the streams sniffed with wireshark, from a computer connected directly to my router. Network administrators (NA) verify successful data packet transmission via broadcast addresses. A message sent to a broadcast address may be received by all network-attached hosts. 70 Convert to Hex:. Alright, time for a different tack; my apologies for the diversion down the multicast route. Secondly, the host will accept the multicast if they have joined the multicast group. Without looking at these routing tables, there is no way to differentiate an anycast address from a unicast address. Global Multicast Addressing: IPv4 and IPv6 This is a short post covering globally unique multicast IP addresses for both IPv4 and IPv6; this does not cover IGMP, MLD, PIM, BGP-MP, MSDP or any other MC technology other than global addressing. Set the NDDS_DISCOVERY_PEERS file/environment variable not to include a multicast address. 1 on port 5000. A multicast address enables a device to send a datagram to a specified set of hosts, known as a multicast group, in different subnetworks. The VLC media player is an amazing piece of software. In general, you should use multicast groups in the administratively scoped range (239. IGMP helps prevent transmission of multicast data packets to ports that don't need them. How do I constrain multicast traffic to specific ports on GS716Tv3? I can't find specific instructions to constrain multicast traffic on the GS715Tv3 smart switch. multicast group address ‒Multicast enabled router(s) connected to subnet sends out periodic queries to all hosts located on subnet ‒Host B in subnet requests group membership (Join) from its local router. Multicast traffic is network traffic that is addressed to a group of IP addresses instead of to a single address. For everyone who wants a source code for a program like wnetwatcher and angry scanner (WiFi Scanner). Point-to-point is a network topology used for establishing one-to-one (1:1) device communications. This means that you have to JOIN a multicast group if you want to receive traffic that belongs to that group. Run the following commands on each cluster member to get the list of the Multicast MAC addresses that were associated with Cluster Virtual interfaces:. Accessing your router for this information can sometimes be a lot easier than trying to find the address on some devices such as a security camera, DVR, or another device. So if the application tries to queue an APS Broadcast or an APS Multicast (which relies on the broadcast mechanism at the NWK layer) after this broadcast table is full (due to other NWK layer broadcast activity created by APS Broadcasts, APS Multicasts, Route Discoveries, Address Discoveries, Device Announcements, etc. mrouted uses its built-in RIP to construct its distribution tree, and pimd relies on an external routing protocol like OSPF, RIP, or even a manually set up routing table on each router. Because Multicast works only in WinPE mode, you have the choice to put your applications in the default WIM image. Multicast forwarding is a one-to-many or many-to-many distribution of network traffic (as opposed to unicast's one-to-one forwarding scheme). All available RTSP URL formats for IP cameras are listed in table below. The first half of a multicast MAC address is 01-00-5E so we need to work out the second half. I have simply used publicly available code to show one way to get scripted input to listen on a multicast address and port to index mutlticast data. Ping your multicast network! If you have never logged into a *nix box on your network or onto a core router (if you have one) and ping-ed a couple multicast addresses your missing some fun. - Nikhil Mulley Dec 2 '11 at 4:31. An IPv6 packet sent to a multicast address is delivered to all interfaces identified by the multicast address. Otherwise, you can do it in Windows by using tracert ip in cmd. The MAC address is listed as the WiFi MAC address. If you know a way, let me know in the comments section. Exactly what is a MAC address, and how do I find it? Our Small Business Networking Expert Explains 'MAC Address' MAC is an acronym and stands for Media Access Control. The range of MAC addresses used for multicast is therefore 0x0100. Multicast address is synonymous with group address. As Spiff said, to send packets on a multicast address, you can use the ping command but if you want to use it for an application purpose, prefer to use private multicast addresses (in the range of 239. 2 is the all-routers group. Multicast has been extended and improved so that all broadcasting features can now be implemented with some form of multicasting. One of the disadvantages is that Multicast NLB requires additional configuration at the connected switches, so, you have to create a static ARP entry on the switch which binds the Cluster IP address (VIP = Virtual IP address) to the shared Cluster MAC address. The VLC media player is an amazing piece of software. NET as well as the method in which multicasting works and why it is useful now and how, with the increasing availability of bandwidth and the increased use of streaming media, will become a definitive. Multicast is usually sent at a very low data rate, sometimes as low as 1 Mbps. We can find the available network cards in couple ways. A host that is configured to receive datagrams sent to a multicast address becomes part of a multicast group for that address. Thanks! From our perspe. We shouldn't have to do this though, it should be dynamic on the client side. We have a Multicast IP Address 224. cyruslab IP Multicast , Route September 14, 2010 September 20, 2010 2 Minutes Scenario: ABC corporation and XYZ company has merged into one huge organization known as EFG. That is all IP address from 224. The attached screen dump shows some of the streams sniffed with wireshark, from a computer connected directly to my router. Category: Standards Track. The multicast address range is 224. For example, a host that listens to the 239. group (multicast group address Default: 224. Multicast delivery: RTP over UDP. The valid range of Multicast addresses in the administratively scoped IP version 4 (IPv4) multicast address space is the range from 239. 1D supporting this. The multicast addresses are in the range 224. I started to explore multicast network technology and talk about it from previous post. In Ethernet networks, it can be a MAC address. If you do not have access to router admin interface (via telnet or webbased), use following method to find out router MAC address. " Yes, that's very similar to broadcast. 5e and the range is from 0100. show ip mroute. I am trying to find the MAC address of the interface from within the CLI but am having no luck. My question is how do I know if this is multicast or unicast? Again I note that there is nothing in the file. To ensure smooth traffic flow for IGMP and multicast, the PC and STB must be in the same address space within a single network device. How to determine if an IP address is host, broadcast or network Hey guys. IPv6 multicast addresses use the prefix ff00::/8, shown in Table 4-10, which is equivalent to the IPv4 multicast address 224. Exchanging address information, such as the exact Broadcast IP address and Multicast IP address to be used during the session. When the switch receives the frame with the multicast MAC address, it will forward the frame out all ports to all connected devices. And some keys. A multicast group is determined by a multicast ip address and a port number. To explain it in more clear way, 128 bit IPv6 global unicast addresses has two 64-bit parts. Why is it important to be able to distinguish between the 3 types of Ethernet address type? In an Ethernet switch, each of the three are treated differently. When we start to have one multicast connected which means all the LAN devices will receive the broadcast video stream from the router. No host can have this as IP address, but every machine can join a multicast address group. In the TCP/IP protocol, the unique identifier for a computer is called its IP address. A multicast router builds tables to instead find the reverse path, from the receiver (who requests multicast) to the source of the multicast distribution tree. The multicast IP addresses above all map to the same multicast MAC address (01-00-5E-01-01-01). Use the router pim command to enter Global PIM profile mode and define the RP address and group range. We can find the available network cards in couple ways. Its on the phone itself, you program network setting 9. 0000 to 0x0100. - Nikhil Mulley Dec 2 '11 at 4:31. There, let's continue now. 74:5500 in VLC, but the only thing I get is the following message in the debug console. The [group] is a multicast address of the group to be displayed. Explanation. 6 all the OSPF routers that are sending hellos out will answer your ping. For more information and an example of how to do this, refer to KB21589 - Firewall Filter Examples to verify Multicast traffic is reaching the EX switch. X" (your lo0 address on your core switch) 4) add a staic mroute on the Server Access switch to route the multicast traffic over the tunnel and avoid RFP failure. You might find this link helpful in getting it working, as you aren’t the first person to find there is no transmitter data in dvb-apps for Portugal. This is inherent in the design. 3 -g QAPartition -b 192. Compute MAC address to IPv6 is a an utility that can help you retrieve the MAC address of your computer then change it to an IPv6 address with just a couple of clicks. Final step is to configure RP in order to receivers to find multicast source in the network. Mostly working with WowzaStreamingEngine, I wish to show principles and milestones configuration there. Notice that it begins with ff (ff00::/8), the IPv6 multicast range. With IP multicasting the hardware multicasting MAC address is mapped to an IP Address. I think the Satoshi client uses Universal Plug-n-Play (upnp) to find other Bitcoin nodes. On Lease Duration page, I will leave it as default. Special multicast addresses in the MAC address begin with 01-00-5E. Learn how to use a UDP Multicast in c# to quickly send data from one machine to a next. The multicast addresses are in the range 224. Unlike IPv4 addressing scheme, the IPv6 addressing scheme does not implement broadcast address. To do this we need to convert the last 23 bits of the IP address in question. (This is been decided by the applications. traceroute ip in terminal of MAC or Linux. MPLS Fun in the Lab: Add the Multicast at the Customer – Part 4 of 6. I'll explain below exactly how to determine the multicast MAC address from the multicast IP as well as provide a few helpful websites. Enter the IP address of the multicast group (in the 224. Find your IP address and subnet address. The “classful” IP addressing scheme sets aside a full one-sixteenth of the address space for multicast addresses: Class D. Notes about address collisions. mDNS is stand for multicast Domain Name System. Address assignments are listed below. b: you can connect to multicast clusters with the WAN features. Java supports this with the help of an API called isMulticastAddress(). The IP address used in the example was 203. 00000001  (32 bits)Our Multicast Address’s fixed part will be like below. Method 1 - Using 'ifconfig' Command:. If routing multicast, ensure that the Multicast Packets have a Time to Live (TTL) of greater than 1 so it will not be dropped at the 1st router hop; If multicast is not working with the server and client on the same VLAN check for IGMP groups. These mac addresses are all start with a odd number as the first octet. Secondly, the host will accept the multicast if they have joined the multicast group. Multicast address settings: This comes down to if you wish to allow the IPv4 IP address ranges to use any IP range in the environment or if you wish to restrict it limiting the field per say to only a specific range of IP Addresses. The multicast addresses and ports used are configured using the socket-binding elements in standalone. 0, whereas new devices are shipped with DHCP enabled which means they will automatically be assigned an IP address that corresponds to your local network. (This is been decided by the applications. 0/4 , but some addresses are reserved for special purposes (e. 5 bits from IP address becomes don’t care and hence 32(2^5) multicast IP addresses maps to same MC MAC address. Is there som. --udp) command line switch may be used to control the multicast address used by the JGroups channels opened by all standard AS services.

If you want something to dial an extension for an overhead page there are things like this. WDS Multicast is a service program running in the background that listens to WDS requests against a networking port. Neither hosts or routers maintain a list of individual group members. Send a ping to the link-local all-nodes multicast address, and you'll receive a response from the address of every device connected to that link that responds to pings. Broadcasts and multicasts are also used for dynamic address assignment, which occurs when a station is first powered on and needs to find a high-level network address. Mostly working with WowzaStreamingEngine, I wish to show principles and milestones configuration there. Let's find the Multicast MAC address of this address and the other Multicast IP Addresses which has the same MAC address. The MAC address is listed as the WiFi MAC address. Broadcast uses a one-to-all association. ), the stack will refuse to queue the message and instead will return EMBER _ NETWORK _ BUSY status. I am trying to find the MAC address of the interface from within the CLI but am having no luck. Since TCP supports only the unicast mode, multicast applications must use the UDP transport protocol. A number of multicast addresses have been assigned; see Ethernet numbers at the IANA, Michael A. The source simply transmits multicast streams to the IP multicast address of its multicast group, then lets the network handle multicast data delivery. Multicast addresses ^ Multicast addresses are also known in IPv4. You could also allow all inbound udp traffic but I would recommend this for testing only ;-). cyruslab IP Multicast , Route September 14, 2010 September 20, 2010 2 Minutes Scenario: ABC corporation and XYZ company has merged into one huge organization known as EFG. If you look at the various hardware addresses in one of your device's mac-address or arp tables, you shouldn't find any stations where the first byte is an odd number because stations must use unicast addresses. 1 multicast IP address will configure its network card to listen to MAC address 01-00-5E-01-01-01. Older Hikvision devices are shipped with a static IP address of 192. Rather than using the network address of the intended recipient for its destination address, multicast uses a special destination address to logically identify a group of receivers. IP addresses in the range 224. Multicast allows a single network packet to be delivered to a group of receivers. The ChromeCast response is a uPnP UDP message, containing address details for the ChromeCast device. on source and destination address, and to perform NAT on multicast packets. What is easier to configure than specific broadcast addresses in the ACL of a ip multicast helper-address command? any any eq - the reference guide specifies a. Enabling multicast routing initially does not route any data, due in fact that the default configuration leaves all router interfaces without multicast routing in their configuration. Administrators used to select a multicast address and configure both senders and receivers to use this specific multicast address. The omping is program which uses User Datagram Protocol to determine if computer is able to send and/or receive IP unicast and multicast or Broadcast packets from the network. This is the address assigned to "all systems on this subnet. Dynamic Host Configuration Protocol (DHCP) and Bootstrap Protocol (BOOTP). Akamai’s Licensed Multicast Solution ( LMS) is licensed software for Pay TV and network operators who seek to offer a diverse, higher-quality mix of services over their broadband networks — without having to overspend on network buildout. These messages are send by nodes when they boot up to find any routers in a local segment. If address object is being used by multicast zone and multicast mode is not enabled globally and on interface, then follow the steps below to enable multicast mode: 1. If you bind your DatagramSocket to the IP of a local interface, and then. This method is commonly refered to as a UDP rendezvous. I developed a new VI (in LabVIEW 2017) to find UPnP devices, which looks a bit different than your approach. 0/4, but some addresses are reserved for special purposes (e. Multicast Address - A multicast IP address is identifier for a set of interfaces that may belong to differentn nodes. The attached screen dump shows some of the streams sniffed with wireshark, from a computer connected directly to my router. Converting Multicast Ip To Mac Address freeware for FREE downloads at WinSite. This document describes address allocation for private internets. That’s all well and good, but it doesn’t block Bonjour because it’s only part of the solution.

IP multicast is most often used for streaming media, such as video and voice over IP (VOIP). With this mapping, each Ethernet Multicast address correspings to 32 different IP Multicast Addresses (2^5) This means that a host in one multicast group may have to filter out multicast that are intended for other groups sharing the same ehthernet address. Hi, I have configured a cluster with the multicast address and multicast port number. The MAC address is listed as the WiFi MAC address. The IP address used in the example was 203. Compared with broadcast, the packets are only sent to the members of a multicast group with the help of a multicast router. Optimizing Multicast Rate for Home Use Multicast Rate is usually an often talked about “advanced” router option that can seriously hinder your wireless use experience if you misconfigure it. As a Linux user we should know about some network properties like network card name, speed's, driver details etc. Multicast address: 239. x is used by bonjour and other consumer-friendly protocols, so there is a higher chance of them working out of the box. 255 ( Class D addresses) belongs to multicast. A huge list of devices having Multicast option is being composed by our writers and will be available soon. 11) for the controller to respond to the APs’ queries. 0 through 239. multicast group address ‒Multicast enabled router(s) connected to subnet sends out periodic queries to all hosts located on subnet ‒Host B in subnet requests group membership (Join) from its local router. In the TCP/IP protocol, the unique identifier for a computer is called its IP address. The information is delivered to each of the links only once, and copies are created when the links to the destinations split, thus creating an optimal distribution path. In an environment where there is one source of a video stream and many viewers, ideally each frame of video and audio would only transit the network once. 0/4 , but some addresses are reserved for special purposes (e. Distance Vector Multicast protocol is one of them. IPv4 Multicast Address Space Registry. For example, a host that listens to the 239. Finally another technician changed the configuration of the Mikrotik and everything works perfectly since then. In addition, Windows Sockets enables developers to selectively allow additional broadcasters in a given source/group pair, or enables applications to block specific broadcasters. In response to the queries, multicast listeners reply with membership reports. Then disconnect the problem host. Convert IP address into binary. The multicast IP addresses above all map to the same multicast MAC address (01-00-5E-01-01-01). Note that a multicast IP address is defined in the range of 224. The IP address space for the inter-host VXLAN communication may be sourced from a different VRF. In the example shown in Figure 1, a multicast source on the Marketing network with IP address 192. 255 Globally-scoped (Internet-wide) multicast addresses 239. My IP Address 228. The information is delivered to each of the links only once, and copies are created when the links to the destinations split, thus creating an optimal distribution path. 254/24 ip igmp ip pim sparse-mode Using a DSCP value to prioritize traffic The VoIP service on the network already uses DiffServ marking (DSCP) to identify. And some keys. Starting with Ghost 6. Multicast can be used to send IP packets to a group of interested receivers. Because, there are 32 Multicast IP addresses that corresponds to a Multicast MAC Address. 00000001  (32 bits)Our Multicast Address’s fixed part will be like below. IPv4 Multicast Address Space Registry. A number of multicast addresses have been assigned; see Ethernet numbers at the IANA, Michael A. X" (your lo0 address on your core switch) 4) add a staic mroute on the Server Access switch to route the multicast traffic over the tunnel and avoid RFP failure. Simple Multicast Testing Tool for Windows After multicast has been configured on the network, one of the biggest challenges tends to involve actually testing multicast functionality in between two Windows machines (physical or VMs) connected via the network. With IP multicasting the hardware multicasting MAC address is mapped to an IP Address. Anycasting is done with Unicast addresses in the routing tables of multiple addresses. SDN and NFV is the next phase of technology change which will help service provider to launch the services in single click. You may be able to find something that builds on socket and is easier to use. But linux kernel is not allowing. How should I choose an IPv4 multicast address for my application's use? I may need more than one (a whole range perhaps ultimately) but just want to avoid conflicts with other applications. The "classful" IP addressing scheme sets aside a full one-sixteenth of the address space for multicast addresses: Class D. Multicast addresses in IPV6 have the prefix ff00::/8. One of the important requirements of PIM Sparse Mode, and Bi-directional PIM, is the ability to discover the address of a RP for a multicast group using a shared tree. Typically, Class D networks with a range of IP addresses from 224. 28 bits remaining to choose unique address. You’ll find everything from specific commands to start-to-finish methodologies: all you need to deliver and optimize any IP multicast solution. If you are using the latest Raspbian Jessie, click here to read our updated guide. A datagram from a singular sender is routed to all endpoints associated with the broadbast address. Multicast address settings: This comes down to if you wish to allow the IPv4 IP address ranges to use any IP range in the environment or if you wish to restrict it limiting the field per say to only a specific range of IP Addresses. A special multicast:// URL can be used in the InitialContext properties to signify that multicast should be used to seed the connection process. The multicast MAC address is set to 03-BF-1-2-3-4 for a cluster's primary IP address of 1. As a Linux user we should know about some network properties like network card name, speed's, driver details etc. 94, you should probably replace that with the IP address which you have on eth0 or similar. Subject: RE: How to multicast audio to 50+ ip phones?.
