Cisco Switching/Routing :: 6509 / Multicast Heartbeat On Servers

Feb 25, 2013

The two servers (red hat) use multicast for their heartbeat. Unrouted vlan 99 (only layer 2) is configured on the VTP Servers (6509).I have read this document [URL]
 
Switches 1 and 2 have IOS: c2960s-universalk9-mz.122-55.SE3.bin
and the 6509: s72033-advipservicesk9_wan-mz.122-18.SXF17a.bin
 
IGMP snooping is enabled on the 2960 switches.In order for the heartbeat of the servers to work, I have tried these solutions:disable igmp snooping for vlan 99 on switch-1 & switch-2. (No additional action was taken on the 6509). This didn't work. I expected that the multicast traffic would be sent as broadcast throughout the network, but for some reason it didn't work.on switch-1 & switch-2 configured "ip igmp snooping vlan 99 querier" (no additional actions on 6509). Didn't work either.on switch-1 & switch-2 configured "ip igmp snooping vlan 99 mrouter interface gigabitEthernet 1/0/25" & "ip igmp snooping vlan 99 mrouter interface gigabitEthernet 1/0/26" for the two connections to the 6509. Again no actions taken on 6509. Didn't work. I want static mac entries on the switches to be my last resort, since the number of red hat servers on the network is going to increase and I want to give a more generic solution to the issue.

Cisco Switching/Routing :: 6509 - IP Multicast Rate Limit

Nov 26, 2012

How is it i can implement the command 'ip multicast rate-limit out group-list <access-list>' but i get the error "ip multicast rate-limit" command is not supported on 6509?

Is it an IOS limitation or a limitation of the switch series and subsequently can't be used at all?

Cisco Switching/Routing :: 6509 - Multicast Routing Preference

Nov 14, 2012

I have a problem on my catalyst 6509 on which I would like to do the following things :
 
I have some Vlans in which multicast is enabled.
In tose Vlan theres is a router which is default router for equipements.
 
I had enabled multicast routing because some Vlan needs to exchange multicast informations, but I wolud like to make difference between Multicast traffic. For example I have 5 vlans:
 
Vlan 1 and 2 need to exchange Multicast informations but the don't need multicast information from Vlan 3 and 4
Vlan 3 and 5 need to exchange Multicast informations but the don't need multicast information from Vlan 1 and 2
Vlan 5 is independant Vlan but doesn't need to have multicast information from all others vlan.
 
Last problem, equipement on differents vlan can use the same Mulkticast group address. In this case, Multicast routing is not working between Vlan 1 to Vlan 2 and Vlan 3 to Vlan 4.

Cisco Switching/Routing :: Test Multicast Between VRFs Configured On Nexus 7Ks?

Jan 11, 2012

We are trying to test multicast between VRFs configured on Nexus 7Ks. Two Nexus 7Ks are configured for VPC. Multicast Server is in one VRF where as Receiver is in another VRF. The two VRFs are connected to each other via Checkpoint Firewall (Active/Active cluster in unicast mode). All routes have been established and connectivity tested between multicast server and receiver using ICMP.Using, windows mcast.exe multicast stream is generated from server (in one VRF) intended to be received by receiver (in second VRF). Every time, only one multicast packet is received by the receiver and rest all packets are being dropped. Server and Receiver are VirtualMachines configured on VMWaresame chassis which is connected to two Nexus 5Ks (VPC configured).

Cisco Switching/Routing :: Nexus 7000 / How To Have Multicast Data Across OTV Extensions

Nov 5, 2012

have multicast data across OTV extensions?  We run OTV between two pairs of Nexus 7000 in different datacenters with mcast underlying encapsulation. We stretch 10 or so vlans between the sites. We have encountered multiple bugs over the last two years and had to upgrade code and have rarely been clear for any period of time.
 
We've had an ongoing Tac case where IGMP requests are not getting across the OTV VLAN extension to the PIM forwarder on another site. You can see OTV IGMP snooping on the AED VDC is picking up the request on the local site but it does not get to the remote site that is the PIM forwarder so no multicast gets onto the VLAN. For a while we had a hack where we would get a local server to the PIM forwarder router to request the same groups and then this would somehow get across to the other site. Since clearing the overlay interfaces to try and fix the original problem the hack no longer works and I can't get multicast to the receiver at all.

Cisco Switching/Routing :: Nexus 4000 Won't Connect To 6509?

Sep 12, 2011

we have a new IBM Bladechassie with two Cisco nexus 4001i switches.I have configured one external port on each nexus and connected them to a cisco 6509 with 1G cisco SFP-modules and MM fibre.Both the nexus and 6509 ports are configured as trunk ports, and set speed to 1000.I see light in the SFP-modules on both devices, and through the fibre. When I connect the devices, the link doesn't come up. No light on the ports, the nexus says "link not connected", and the 6509 says "notconnect". I have tried reconfiguring the ports in many ways, even as accessports, nothing seems to work. If I move the SFP and fibre from the 6509 over to a trunk port on a cisco c2960-24TC-L, the link comes up and everything is working fine. why this work on a 2960 and not my 6509 coreswitch? One of the configs I've tried on the 6509:interface GigabitEthernet2/20description *IBM Bladechassie 2 NW1*switchportswitchport trunk encapsulation dot1qswitchport trunk native vlan 34switchport trunk allowed vlan 34switchport mode trunkend

Cisco Switching/Routing :: Nexus 5548 And 6509 VPC Connectivity?

Nov 12, 2012

We have two 5548 switches connected to a pair of 6509 running in VSS mode. I am trying to understand the benefit of having bridge assurance on the uplink ports.
 
If we have the command spanning-tree port type network enabled we cannot do a non disruptive upgrade. If there is bridge assurance on the uplink it warns you of this. Yet if I do not run bridge assurance on the uplinks I can do a upgrade without any disruption.
 
Why in god would I enable bridge assurance on this VPC link if I cannot do a non disruptive upgrade?

Cisco Switching/Routing :: 6509 - Nexus And Span Sessions

Oct 24, 2011

I am in the early planning stages for a 6509 to Nexus 7K migration. Based on my experience with the 7K's at a previous company where we ran into a lot of issues, I am trying to be very careful.
 
I am more at home with the 6500 chassis and know what I can do with them.  I remember running into a limitation on the Nexus that involved their not supporting span sessions like the 6500's do.  Is that still the case ? 
 
If that isnt an option in the short term, I will need to look at a substantial investment in ethernet tap's to replace the lost span functionality because the security group's heavy use of span sessions.

Cisco Switching/Routing :: 6509 - Load Balancing Nexus Switches

Jan 24, 2013

I am trying to understand what load balancing method is used on a port channel on a Nexus switch . I have a server connected by a VPC to two Nexus switches. The nexus switches are only acting as layer 2 switches. I have a 6509 connected via a upstream link that does all of the routing for my VLANS. If  have a server connected to the Nexus switches and it talks to a server on my 6509 what load balancing happens on the Nexus going across VPC 27 which is a layer 2 trunk going up to my 6509. Is it done on layer 2 or layer 3 flows?
 
My Nexus shows the default load balancing configurations

Cisco Switching/Routing :: 6509 - Nexus Dual Homing With N2000

Oct 24, 2011

I am trying to work up a config based on equipment that was ordered before I joined my current employer.
 
I will be deploying N2Ks at the top of each rack.  Each N2K will be dual homed to two different N5K's. Being new to the Nexus, I understand that the N2K's have no brains and are dependent on the N5K's they connected to. Wasnt sure how to tell each 5K that the 2K that was dual connected to it needed to be able to move between N5K's based on failure/availability. I havent been able to find a sample config of what this will look like anywhere on the Nexus section of the Cisco site.
 
The next step after this will be to connect N5K_1 to blade on a 6509 and N5K_2 to a different blade on the same 6509.  I will be installing two of the 10Gig blades in the 6509. Havent been able to find any sample configs on what this would look like either.  We are upgrading the sup engines on the 6509 to the new 2T version.

Cisco Switching/Routing :: 6509 - Nexus 7009 Rack Concerns

Mar 5, 2013

I wanted to know if any has the Nexus 7009 chassis installed into a 600 wide rack with the sides fitted and if they are experiencing heat issues? 
 
My client will be replacing their aging 6509 chassis with 7009 devices, but the physicals dont tally with the install guidelines for the 7009 series chassis.  The current install of the 6509s does not tally with the recommended install guidelines for those either, but they have not expereienced any heat issues...
 
The 7009 will be fitted with 2xSUP2E, 3x48portSFP-F2E cards and 2x10GSFP-M2 cards with 2x6K PSUs.  I am genuinely concerned they may cook these devices, but space restrictions look like vetoing the upgrade to 800 wide racks.  Likewise moving to 7010 chassis may prove tricky due to existing other installs within the racks limiting vertical space.

Cisco WAN :: Multicast Routing Between Two Nexus 7Ks?

Dec 9, 2012

I have multicast routing setup between two Nexus 7K's.These Nexus 7K's act as the distribution layer and they connect to 48 different 4507 access layer switches (VPC) and 3 6509 core layer switches.The 4507 swiches have two supervisor modules.  One acting as active and the other as hot standby.  Let's assume that multicast is working on the active module.  If I pull out the active module the hot standby takes it's place. This is where multicast stops working on the switch.How can I get both Nexus 7K's to work with multicast at the same time. Here is an example of show ip mroute from both Nexus 7K's:note that DR02 has a lot more entries in the routing table.  Is this working as designed?

Cisco WAN :: 4948 / 6509 / 2960 - How To Implement Multicast On Network

Aug 4, 2011

We want to implement multicast on our network. We are going to use for  online teaching purpose. I am very new at Multicast and not have much  idea about it. We are not running any routing protocol in our network,  only static route. The multicast server is located at One of our office  and it is connected with L2 (Cisco 2960) switch, L2 switch is connected  to L3 switch(Cisco 4948). L3(Cisco 4948) and Core Switch(Cisco 6509)  with FWSM are connected with E-3 link with tunnel. Router 1 and Router 2  are connected with P2P ILL links which are terminated at serial  interface. The Multicast Server IP is 192.168.2.131/25. The scenario of  our network are mentioned below:
 
Multicast  Server--->(L2 Switch)--->(L3 Switch)--->(Core  Switch)--->(FWSM)--->(Router 1)---->(Router 2)--->(L2  Switch)--->(Multicast Client)
 
 We  have created a seprate vlan (i.e. vlan 102,   interface IP is 192.168.2.129/25) for multicast at L3 switch, enable  multicast routing, defined rp-address(i.e. 192.168.2.129/25), enable  sparse-dense mode at multicast vlan as well as at some other vlan also  for testing purpose and joined multicast group (i.e. Multicast IP is  224.3.3.5). At core switch we have also enabled multicast routing,  defined rp-address (i.e. 19.268.2.129/25), enable sparse-dense mode at  user vlan and inside vlan of FWSM and joined multicast group at user  vlan and inside vlan. At FWSM we have enabled multicast routing, defined  rp-address(192.168.2.129), doesn’t find any option to enable  sparse-dense mode and joined Multicast group at inside vlan and router 1  vlan. At Router 1, we have configured the same thing. We have  configured mroute at all the devices. We are able to ping from end to  end. We are testing multicast by Multicast IP checker tool (provided by  vendor). Multicast is working fine at L2 switch, L3 switch and Core  Switch, but not from Router 1. Ping is reachable from Router 1. After  doing mtrace at Router 1, the following output has come:
 
Router 1 (Mtrace with destination address 192.168.2.131)
mtrace 172.21.15.2 192.168.2.131 224.3.3.5
 
Type escape sequence to abort.
Mtrace from 172.21.254.50 to 192.168.2.131 via group 224.3.3.5
From source (?) to destination (?)
[Code] .....
 
If , we do mtrace from gateway IP address(i.e. 192.168.2.129) as  destination address then mtrace is getting completed, but if mtrace is  done from Mutlicast server IP address(192.168.2.131) as destination  address, then mtrace is not getting completed.
 
  We  have connected one laptop at Router 1 vlan to test Multicast. The host,  which is connected to Router 1 vlan is able to send multicast packet to  other host and other host at different vlan are receiving it , but it’s  unable to receive multicast packet send by other host of different vlan.
 
Do I need to enable igmp snooping at L2 switch, L3 switch and Core Switch ? I am not able to understand or can't figure out where i have configured wrong.

Cisco Switching/Routing :: 2821 Multicast Routing Relay Basic

Mar 12, 2013

I  start configuring Cisco 2821 router for multicast . First short  description and attached sheme explanation. Let we say  I have small  network with 100 users. One router and Cisco switch 3560. Two VLAN’s,  one for data another for multicast. Data from internet works fine but  now I want to connect multicast servers (or source of more multicast  streams) from another subnet. Router have three interfaces.I expect there should be no problems with multicast configuration, but unfortunately it is not like I expect. What I did ?

First step:  enable multicast routing

Second step: on both interfaces (Fe 0/1 and Fe 0/2)  - ip pim sparse-mode

Third step: configure switch that users are connected to access port in VLAN 222 (temporary to see if multicast work)
 
When  I start VLC on computer nothing happend. If I try to connect computer  on same subnet where is source of multicast streams it works fine.What  I am doing wrong ? Is there anything about routing ? All subnets are  directly connected. RP is not needed if I have one router or ?

Cisco Switching/Routing :: 4506 / 6506 - Multicast Routing

Mar 8, 2013

I am configuring multicast in a environment where I have a 4506 at each site (4 total) and a 6506 as the core. Each 4506 is connected via layer 3 to the 6506. I have a mix of 3560s, 3548s, and 2960s connected to the 4506s and the 6506 via layer 2 trunk
 
I have multiple multicast sources and hosts communicating at a time (multiple cameras sending video / multiple computers receiving video).  So this is not a scenario where there is 1 sender and many receivers.  This would be many senders (~50) and some receivers (~10)
 
Sample Diagram:
 
->3560
|
6506 --> 4506 --> 3548
|   |
|    --> 2960
|
4506 --> 2960
|
-->3548
 
I configured ip multicast-routing on each of the 4506s and on the 6506. IGMP snooping is on by default on the 3560 and 2960 switches. CGMP is on by default on the 3548 switches.
 
I set up PIM sparse-dense mode and IGMP version 3 on each of the layer 3 interfaces for the 4506s and 6506 where they connect and on each VLAN that is sending or receiving multicast. Multicast is working throughout the network, however I am looking to verify the configuration as I scale this out to more clients on the network. 
 
#1 - Is it correct to us sparse-dense mode in this configuration?
 
#2 - Do I need to configure a rendezvous points using AUTO-RP? (ip pim send-rp-announce INTERFACE scope TTL). Not sure here if I need to designate this and what to choose.  Right now I do not have this and it is working, but documentation seems to infer that I need to designate this.
 
#3 - Is there any other configuration settings I should be considering?  I hard to find real world configurations of multicast as examples or people that know multicast routing well.
