Hi,
I need to create a multicast network. I have 2360 and 6865
This is my network :
Stream Server ----> 2360 <---------> 6865 (Core) <----------> 2360 <--------Users
We have 6 vlans to declare on the core, each with an IP address for inter-vlan routing, but multicast must only be active on the Video vlan (vlan 30).
Here's the configuration on the core:
! IPMS:
ip multicast admin-state enable
ip multicast querying enable
ip multicast querier-forwarding enable
ip multicast vlan 10 admin-state disable
ip multicast vlan 20 admin-state disable
ip multicast vlan 30 admin-state enable
ip multicast vlan 40 admin-state disable
ip multicast vlan 50 admin-state disable
ip multicast vlan 55 admin-state disable
On the switch where the server is connected:
! IPMS:
ip multicast admin-state enable
ip multicast querying enable
ip multicast querier-forwarding enable
ip multicast vlan 10 admin-state disable
ip multicast vlan 20 admin-state disable
ip multicast vlan 30 admin-state enable
ip multicast vlan 40 admin-state disable
ip multicast vlan 50 admin-state disable
ip multicast vlan 55 admin-state disable
On the switch where users are connected:
! IPMS:
ip multicast admin-state enable
ip multicast querier-forwarding enable
ip multicast vlan 10 admin-state disable
ip multicast vlan 20 admin-state disable
ip multicast vlan 30 admin-state enable
ip multicast vlan 40 admin-state disable
ip multicast vlan 50 admin-state disable
ip multicast vlan 55 admin-state disable
Despite this configuration, if I test with Iperf, the packets sent by the client are not received by the server.
I must have a problem somewhere...
Can you help me?
Thanks you

Re: Multicast Configuration
Hi,
I have not much experience with multicast nor with 2360 switches, so I am no expert on this topic.
Nevertheless I would guess that your multicast should be sent from the server and be received by the clients, the way you are checking is the other way round. For this to be also possible I would say you need
ip multicast querying enable
on the Client-Switch as well.
Best Regards

Re: Multicast Configuration
The querier needs an IP interface. Does your core have an ip interface within the vlan 30 with the mc traffic.
You only need the querier to activate at the core.
The other config is okay.
check at the other switches the querier (show ip multicast querier). Restart the mc clients....

Re: Multicast Configuration
Thank you for your comments.
I made a modification to my configuration and it seems to work!
When I run the following command on the PC emulating the client ( iperf -c 224.0.0.5 -u -T 32 -t 3 -i 1 -p 7600 ), the server on its side responds well to the requests
I've attached an image of my configuration for those who might find it helpful .
Here is the configuration :
Core Switch :
SURETE|COEUR [U1-U2] -> sh configuration snapshot ipms
! IPMS:
ip multicast admin-state enable
ip multicast querying enable
ip multicast querier-forwarding enable
ip multicast vlan 10 admin-state disable
ip multicast vlan 20 admin-state disable
ip multicast vlan 30 admin-state enable
ip multicast vlan 40 admin-state disable
ip multicast vlan 50 admin-state disable
ip multicast vlan 55 admin-state disable
Server Switch :
SURETE|RG [U1&U2] -> sh configuration snapshot ipms
! IPMS:
ip multicast admin-state enable
ip multicast querier-forwarding enable
ip multicast vlan 10 admin-state disable
ip multicast vlan 20 admin-state disable
ip multicast vlan 30 admin-state enable
ip multicast vlan 40 admin-state disable
ip multicast vlan 50 admin-state disable
ip multicast vlan 55 admin-state disable
User Switch :
SURETE|SR12 [U1-U2] -> sh configuration snapshot ipms
! IPMS:
ip multicast admin-state enable
ip multicast querier-forwarding enable
ip multicast vlan 10 admin-state disable
ip multicast vlan 20 admin-state disable
ip multicast vlan 30 admin-state enable
ip multicast vlan 40 admin-state disable
