Multicast in 115001 csm

hi
i installed a content switch which has to pass both multicast and unicast packets arriving from internet adn intranet. but there seems to be trouble in passing the multicast packets. do we have to enable multicast in the switch or is it enabled by default. plz help

hi
another thing i would like to add is that above the csm 11501 there is L3 switch on which a tunnel is terminating for intranet. the igmp group for multicast is 224.1.1.61 . is it bcoz of diff group that L3 is not showing any multicast . how shud i make my csm to join this group

  • MPLS, Multicast and CSM

    Hi Folks!
    I'd like to know if is it possible to forward MPLS and Multicast traffic through a CSM ?
    Gilles, Id like to see your comments about it.
    thanks in advance !
    Cristiano

    I did the test and it works but only in bridge mode.
    I could establish ospf through the CSM between 2 routers configured for mpls.
    OSPF comes up - so multicast can go through the csm.
    I could form TDP adjecency and learn all the tags.
    Then I sent some traffic in mpls and it went through the csm.
    The CSM does not understand the mpls traffic, it is just passing it through like a L2 switch.
    Again, this requires the use of bridge mode.
    This does not work in routing/secure mode.
    Regards.

  • Allowing Multicast to work between real servers behind the CSM??

    Hi,
    Just want to know if it is possible to use IP Multicast between real servers on a server subnet that is configured on the CSM. If so how could this be setup?
    I've attached a copy of the our CSM config. In particular, the server subnet in question is "vlan 386 server". The Real servers belong to "serverfarm FARM-VISTA-TEST".
    I suspect that maybe an interface vlan 386 needs to be created on the router, with pim sparse-mode enabled?
    Any ideas?
    thanks
    Sheldon

    the CSM does not know ip multicast, so your multicast needs to find another way to reach the servers.
    You will also need a static route on the servers to point 224.x.x.x to the MSFC and keep the rest of the traffic going to the CSM.
    Another solution is to use bridge mode.
    Create a duplicate vlan 386 on the CSM and the MSFC.
    ie:
    MSFC---vlan387-----CSM-----Vlan386
    On the CSM, you configure vlan387 with the same ip as vlan 386 - this will tell the CSM to bridge the 2 vlans.
    Configure an ip from the same subnet on the msfc int vlan 387.
    configure multicast on vlan 387.
    The CSM should normally bridge all unknown traffic including multicast.
    All you have to do on the servers is change the default gateway to be the MSFC instead of the CSM.

  • General query on CSM and CSS flow timeout values

    Hi all,
    i have a SLB Application Processor Complex module on my Cisco 6504 which basically does some load balancing work. I am pretty new to this device but the configurations and setup looks somewhat similar to the Cisco ACE but i only have some experience with the Cisco CSS.
    What i would like to know is what the equivalent command to the CSS "flow timeout" is on the CSM. Would that be the "idle timeout" command? I understand that the "pending timeout" is more to governing how long it takes to setup a 3 way handshake from client to server and the "idle timeout" is what i am looking for. Please correct me if i am wrong...
    On the CSS, a flow timeout is on 16secs for most standard ports and 8 secs for HTTP. I would like to know what the default setting is for the CSM idle timeout?? Thanks alot!!
    Daniel

    Hi Daniel,
    For Idle Timeout the the default is 1 hour/ 3600 sec.
    As you know for Cicso CSM thare are 2 timers per vserver.
    Idle timeout
    Pending timeout.
    If a connection is timed out it's because of one of these timers.
    Idle timeout per vserver - If there is no traffic neither from client nor server. Idle connection timer duration in seconds; the range is from 0 (connection remains open indefinitely) to 13500000. The default is 1 hour. If you do not specify a duration value, the default value is applied.
    Examples
    This example shows how to specify an idle timer duration of 4000:
    Cat6k-2(config-slb-vserver)# idle 4000
    Pending timeout per vserver - is the max time allowed to complete the 3-way handshake.The default is 30 sec.Range is from 1 to 65535. This is a SLB virtual server configuration submode command. The pending connection timeout sets the response time for terminating connections if a switch becomes flooded with traffic. If the 3-way handshake does not complete within this time, the connection is dropped.
    The CSM expect to see 2-way traffic within the pending timeout. If no traffic is received from the server, the session is removed.
    Examples
    This example shows how to set the number to wait for a connection to be made to the server:
    Cat6k-2(config-slb-vserver)# pending 300
    These are not counted as failures.
    A failure is when the server does not respond or respond with a reset.
    The CSM can hold 1 million connections in memory at the max.
    So, if you set the idle timeout to 10 hours, your max connection rate is 1 M / 10 * 3600 = ~250 conn/sec.
    Assuming they would all be open and then idle.
    When the number of pending connections exceeds a configurable threshold, the CSM begins using the SYN cookies feature, encrypting all of the connection state information in the sequence numbers that it generates. This action prevents the CSM from consuming any flow state for pending (not fully established) TCP connections. This behavior is fully implemented in hardware and provides a good protection against SYN attacks.
    Generic TCP termination
    Some connections may not require TCP termination for Layer 7 load balancing. You can configure any virtual server to terminate all incoming TCP connections before load balancing those connections to the real servers. This configuration allows you to take advantage of all the CSM DoS features located in Layer 4 load-balancing environments.
    To select the traffic type and appropriate timeout value, use the unidirectional command in the SLB virtual server submode.
    [no | default] unidirectional
    some protocol automatically set the 'unidirectional' function.
    For example : UDP.
    You can see if a vserver is unidirectional or bidirectional by doing a 'sho mod csm X vser name detail'
    When a virtual server is configured as unidirectional, it no longer uses the pending timer. Instead, the idle timer will determine when to close idle or errant flows. Because the idle timer has a much longer default duration than the pending timer, be sure to set the idle timer to an appropriate value.
    Use the command  "show module csm slot# stats" to get the details of connection.
    The statistics counters are 32-bit. Totals are accumulated since the last time the counters were cleared.
    Examples
    This example shows how to display SLB statistics:

    Table mentioned below describes the fields in the display.
    Table for "show module csm stats" Command Field Information
    Field
    Description
    Connections Created
    Number of connections that have been created on the CSM.
    Connections Destroyed
    Number of connections that have been destroyed on the CSM.
    Connections Current
    Number of current connections at the time the command was issued.
    Connections Timed-Out
    Number of connections that have timed out, which can occur for the following reasons:
    •connection has been idle (in one or both directions) for longer than the configured idle timeout.
    •TCP connection setup not completed successfully.
    Connections Failed
    Number of connections failed because the server did not respond within the timeout period, or the server replied with a reset.
    Server initiated Connections
    Number of connections created by real servers, the number of current connections, and the number of connections that failed (because the destination is unreachable).
    L4 Load-Balanced Decisions
    Number of Layer 4 load-balancing decisions attempted.
    L4 Rejected Connections
    Number of Layer 4 connections rejected because no real server was available
    L7 Load-Balanced Decisions
    Number of Layer 7 load-balancing decisions attempted.
    L7 Rejected Connections: Total
    Number of Layer 7 connections rejected.
    L7 Rejected Connections: Parser
    Number of Layer 7 connections rejected because the Layer 7 processor in the CSM ran out of session buffers to save the parsing state for multi-packet HTTP headers. The show module csm tech-support proc 3 command will show detailed buffer usage.
    L7 Rejected Connections: Reached max parse len
    Number of Layer 7 connections rejected because the HTTP header in the packet is longer than max-parse-len. When a virtual server is configured with HTTP persistent rebalancing or cookie matching/sticky, the CSM must parse to the end of HTTP header. The default max-parse-len value is 2000 bytes.
    L7 Rejected Connections: Cookie out of mem:
    Number of Layer 7 connections rejected because of no memory to store cookies. When a virtual server is configured with cookie matching, the CSM must save the cookie contents in memory.
    L7 Rejected Connections: Cfg version mismatch
    Number of Layer 7 connections rejected because part of the request was processed with an older version of the configuration. This counter should only increase after configuration changes.
    L7 Rejected Connections: Bad SSL2 format:
    Number of Layer 7 connections rejected because the request is using an unsupported SSL format or the format is not valid SSL.
    L4/L7 Rejected Connections
    Number of Layer 4 and Layer 7 connections rejected for policy related reasons:
    No policy: connection rejected because the request matched a virtual server, but this virtual server did not have a policy configured.
    No policy match: connection rejected because the request matched a virtual server, but the request did not match any policy configured on the virtual server.
    No real: connection rejected because no real server was available to service the request
    ACL denied: connection rejected because a request matched a policy with a client-access-list entry and the entry is configured to deny the request.
    Server Initiated: connection initiated by a real server is rejected.
    Checksum Failures
    Number of checksum failures detected (there are separate counters for IP and TCP failures).
    Redirect Connections
    Number of connections redirected, and the number of redirect connections dropped.
    FTP Connections
    Number of FTP connections opened.
    MAC Frames
    Number of MAC frames received and transmitted on the CSM backplane connection.
    For getting details on all of these commands kindy refer Catalyst 6500 Series Switch Content Switching Module Command Reference, 4.2 URL mentioned below:

  • CSM Fault Tolerance and IGMP Snooping

    For "connection redundancy" the redundancy guide says to turn off IGMP snooping.
    Is there any way around this?
    I need to have multicasting everywhere and I don't want to multicast all streams to every port on this switch.

    Most of the show statements are at the end of the attached file in an earlier post. The vservers details are at the end of this post.
    I have an ARP entry for the VIP - 0001.64f9.1a64, but it does not respond to pings. I tried both the alias and the server vlan IP as the default gateway of the servers.
    I took a trace and found that the VIP sends a TCP reset immediately after a request. I have tried versions 4.2.1 and 4.1.4 with the same result. I wonder if this could be a problem with the Sup720 with 12.2.17d IOS. I also tried the CSM in slots 2 and 3.

  • CSM Support for DHCP

    Is is possible for servers in server vlans to get their addresses via DHCP? I don't see an IP helper command for the CSM.

    actually the #1 factor is the type of traffic that you want to go through the CSM.
    The CSM does not support certain type of traffic but it is able to bridge it.
    DHCP, multicast, ospf,...
    If you have these requirements, you should go for bridging mode.
    Routing mode is more like the easy solution.
    Easy to implement, easy to troubleshoot.
    Bridging requires a little bit more attention.

  • Disabling Multicast in Solaris 10

    Hi,
    I have been searching the internet all morning trying to figure out how to disable solaris 10 multicast. I have no need for it. The best information I could find was to modify the script /lib/svc/method/net-svc and comment out the adding of a route point for multicast near the end of the script.
    I thought that hand modifying the methods of SMF was a big no no in solaris 10. Is there a better way to disable multicast?
    For instance, if I do an ifconfig -a I see that all of my intefaces have the MULTICAST flag set. Is there a way in ifconfig to disable that flag?
    I have seen people put ifconfig options into their /etc/hostname.interface file. I think if I can find the correct ficonfig option I can disable the multicast flag during system boot and that should disable multicast.
    Any comments/suggestions would be welcome.
    Eric

    Now that I have done more research I guess I do not have to turn off the multicasting.
    This problem appeared because during snoop sessions I see MANY of the following messages:
    ? -> (multicast) ETHER Type = 022C ... 53 bytes
    I assumed that one of my machines was doing the multicast. However, I shut down all but one machine and then I removed the multicast route from the route table and the messages still appear. I think that either my cisco switch or cisco router is doing the multicast.
    So I guess I will not turn off the multicast on the machines.
    Does it make sense that the router and/or switch is sending out the multicasts?

  • Unable to receive multicast on a multi network interface host

    Can anyone please help?
    I am not able to receive multicast on a multi network interface host.
    This is the code:
    public class LegacyMulticast {
    public static void main(String[] args) throws IOException {
    InetSocketAddress group = new InetSocketAddress("224.10.20.30", 12345);
    NetworkInterface iface = NetworkInterface.getByName("eth3");
    MulticastSocket socket = new MulticastSocket();
    socket.setSoTimeout(5000);
    socket.joinGroup(group , iface);
    byte[] b = new byte[4096];
    DatagramPacket datagram = new DatagramPacket(b, b.length);
    try {
    socket.receive(datagram);
    System.out.println("Success");
    catch (SocketTimeoutException ste) {
    System.out.println("Failure");
    socket.leaveGroup(group, iface);
    The funny thing is that when I start this code, Wireshark detects IGMP join on the correct network interface caused by joinGroup call, followed by constant UDP traffic on correct port which I aim to receive and finally I see correct IGMP leave caused by leaveGroup call and the UDP traffic stops.
    I just don't receive anything on socket.receive call.
    I am trying to figure this one out for days now. Pls help someone :)
    P.S. I suspected security, but System.getSecurityManager() call returns null.
    P.P.S. I also tried implementing this with NIO, but with same result.

    public class LegacyMulticast {
    public static void main(String[] args) throws IOException {
    InetSocketAddress group = new InetSocketAddress("224.10.20.30", 12345);
    NetworkInterface iface = NetworkInterface.getByName("eth3");
    MulticastSocket socket = new MulticastSocket(12345);
    socket.setSoTimeout(5000);
    socket.joinGroup(group , iface);
    byte[] b = new byte[4096];
    DatagramPacket datagram = new DatagramPacket(b, b.length);
    try {
    socket.receive(datagram);
    System.out.println("Success");
    catch (SocketTimeoutException ste) {
    System.out.println("Failure");
    socket.leaveGroup(group, iface);
    This is still not working.
    The multicast is coming from the network (not localhost), OS is Windows 7.
    When I start a multicast stream localy via VLC application on this same group and port, I receive the traffic in this Java application OK.
    Once again, Wireshark detects IGMP join and leave and multicast traffic flow on eth3 network interface initiated by the Java application, but it just doesn't see the UDP datagrams.

  • What is the diffrence between multicasting and broadcasting?

    hi friends
    What is the diffrence between multicasting and broadcasting?
    i'm bit confused in multicasting and broadcasting.

    Broadcasts go everywhere within a range determined by the sender.
    Broadcasting is deprecated and unliikely to go beyond the nearest router.
    Multicasts go everywhere where receivers have declared they are present.
    Multicast can be implemented beyond routers in a WAN which you control but ISP routers generally don't support it.

  • How to protect a PIM-SM network from unauthorized pim routers and multicast sources?

    Hi,
    we're using pim sparse mode in a customer network with catalyst 2/3/4/6K switches, all multicast routers are redundant with pim dr running for access subnets. RPs are configured with anycast rp.
    A) Is there any possiblity to prevent rogue pim routers/igmp queriers connected to host ports from getting connected to the legal pim routers and from getting involved in the local igmp traffic?
    Maybe like DHCP Snooping used with DHCP. I read that in the latest Sup2T ios (http://www.cisco.com/c/dam/en/us/td/docs/switches/lan/catalyst6500/ios/15-2SY/config_guide/sup2T/15_2_sy_swcg_2T.pdf) there is a feature called 'ipv4 router guard' which does exactly what we're looking for:
    'When configured, the Router Guard feature makes the specified port a host port only. The port is prevented from becoming a router port, even if a multicast router control packets are received. In addition, any control packets normally received from multicast routers, such as IGMP queries and PIM joins, will also be discarded by this filter.'
    Afaik, PIM authentication isn't supported in current catalyst ios versions.
    Using a normal port ACL is not an option in our case because of a management decision.
    B) Is there any possibility to prevent (on a per-subnet basis) rogue sources from sending multicast streams to legal multicast-groups?
    Maybe, can I configure a svi of a host subnet or a host port to drop any incoming multicast stream while still accepting IGMP and sending out legal multicast streams?
    Using 'ip pim accept-register' command on the rp is not an option because we've tons of legal sources which would end in an very huge error-prone acl
    Unfortunately, a normal ACL is not an option here, too.
    Best Regards
    Thorsten

    We use two pim routers in each host subnet for redundancy, they elect the PIM DR.
    Does pim passive mode work here?
    (Config Guide: If the ip pim passive command is configured on an interface enabled for IP multicast, the router will operate this interface in PIM passive mode, which means that the router will not send PIM messages on the interface nor will it accept PIM messages from other routers across this interface. The router will instead consider that it is the only PIM router on the network and thus act as the DR and also as the DF for all bidir-PIM group ranges. IGMP operations are unaffected by this command. ... The redundant PIM stub router topology is not supported. The redundant topology exists when there is more than one PIM router forwarding multicast traffic to a single access domain. PIM messages are blocked, and the PIM asset and designated router election mechanisms are not supported on the PIM passive interfaces.)
    ip pim neighbor-filter maybe would work to prevent rogue pim routers to connect to the legal pim routers but wouldn't rogue pim routers still be able to manipulate the layer2 switch to send all igmp traffic to them and not to the legal pim routers?

  • Application not working on CSM

    Hi ,
    Could some one explain whats the difference between the using the port and using the Any while configuring VIP on CSM?
    After configuring "Any" keyword under the context the application is not  working.
    (NOTE: If I change it to http it works eg:virtual 192.168.1.1 tcp http/port  number)
    Example:
    vserver usa
    virtual 192.168.1.1 tcp any  :-----If i change this "any" keyword with  tcp  port number it works
      replicate csrp sticky
      replicate csrp connection
      no persistent rebalance
      slb-policy fariha
      inservice
    policy fariha
    sticky-group 4
    serverfarm zain
    sticky 4 cookie zain insert
    The IOS running on the CSM is 2.2(3)
    Any help would be appriciated.
    Thanks
    Fariha

    The "tcp any" will allow connections to that Virtual IP on any TCP port.  If it is
    working using the specific port, it should be working using any.  Keep in mind that the CSM will accept and load balance using "tcp any," b
    ut your server may not be listening on that port and will reset the connection.
    As a best practice, you should define the specific port on the vserver for load balancing.  Using the "any" statement has it's purposes, but for general load blancing define the tcp/udp port number for your application.  This is also more secure.

  • How to set up set which NIC card to use for multicast?..

              I just downloaded Rolling Patch 1 for WLS6.0SP2.
              While reading the README file it says
              " ISSUE 42518: Provided a way to set which NIC card to use for multicast traffic
              Can anyone tell me how to set this?. on my WebApplication server it has two NIC
              cards and I want to use the NICcard which is being used to talk to internal network
              for multicast messages.
              One more thing,
              Can anyone one tell how to search for bugs (ISSUES) in weblogic. I am looking
              place where I enter ISSUE number and should get the detailed description of bug/issue

              Thanks for helping,

              Thanks Kumar, I'll try this.
              Does this -Dweblogic.interfaceAddress used only for multicast. Or this is also
              used to talk to AdminServer?.
              The other problem I am facing is when I restart the AdminServer in recovery mode
              it's not finding my WebApp servers, because my webapp servers are on public network
              and my admin (management) server is on private network.
              please look at http://newsgroups.bea.com/cgi-bin/dnewsweb?cmd=article&group=weblogic.developer.interest.management&item=1217&utag=
              , for more details about my problem.

  • Need help to deploy IP Multicast in private network

    Hi,
    I am currently working on a project where there is an urgent requirement to deliver an IP multicast solution.
    The network itself is fairly simple.
    IP Cameras as connected to pairs of Catalyst 2960 switches in 'access nodes'. There are 8 cameras per node, 4 on each switch. There are multiple nodes, 3 at the moment in our testing environment, all trunked together, so 24 cameras in total.
    The Catalyst 2960 switches are trunking to a Core node, which consists of a pair of Catalyst 3750 switches with MHSRP configured for each of 8 VLANs, with 2 DCs and 2 Video storage servers for storing camera footage attached to access ports on those switches. We also have workstations attached to the core node switches which have software installed to view live images and manage the cameras across the network.
    We have no routing - the access switches have default gateways pointing to the VLANs SVIs configured on the core switch, and each function has its on VLAN. InterVLAN routing is enabled on the 3750s and connectivity is working fine.
    I wish to send a TCP stream to the Video Storage servers for storage, and to multicast to the workstations so that the software can see multiple streams from multiple cameras.
    Could someone please suggest a suitable deployment strategy, including how to configure the cameras and switches appropriately to allow this to happen? I am struggling to understand what type of configuration is required.
    Much appreciated. I'm actively viewing this thread for assistance.

    I don't think IP Base supports any PIM mode other than PIM stub routing (unless you know otherwise) so your solution wouldn't work. Or perhaps i am not understanding ?
    Martin
    I think the only way forward is to test what we have already covered.
    I didn't realise this was a test environment so at least you can try all things out without worrying about the production network.
    The thread i linked to suggested that you can get the routing working even without a L3 device capable of running full multicast routing but at the moment the question concerns those extra commands you can't enter. Can you verify they are not available in config mode ?
    An additional problem is because PIM is passive on the SVIs no IGMP queries are being made so there is no way for the switches to work out which ports needs the multicast stream and so it will be flooded.
    There is a function, supported on the 3750s called the IGMP querier function which allows the switch to make IGMP queries per vlan without PIM enabled. We may be able to use this but i have absolutely no idea how it will work with the L3 multicast routing config.
    I recommend you try and get multicast routing working first. If you can get to the stgae where you can send a multicast stream from one vlan to another then you should be able to use wireshark to then see each port in the destination vlan receiving the stream (even when you don't want it to).
    If you can get to that stage we can then try the IGMP snooping querier to see if we can restrict the stream to only those ports that need to receive it. It may be we can't in which case -
    a) you could statically configure the multicast mac address to the relevant ports but this is no scalable and does not allow clients to dynamically join and leave the multicast group
    or
    b) simply allow the stream to be flooded to all ports within the destination vlan. Not ideal and kind of defeats the purpose of multicast but you may have no choice.
    I doubt whether any of this would be supported by Cisco though as i think their position would be to simply upgrade to an IP Services license although in understand this may not be possible for you because of cost.
