Hello,
I have a switch where I have to activate IGMP snooping and querier. Without it, my video streams are degraded. Despite activating the :
bridge multicast filtering
interface vlan 20
name PROD
ip address 10.11.0.252 255.255.0.0
ip igmp snooping
ip igmp snooping vlan 20 querier
The flows remain degraded. I ran the test on a catalyst switch and the simple command ip igmp snooping querier solved the problem.
The following commands return the following results:
sh ip igmp interface
vlan 20 is Up
Administrative IGMP status is Down
Operational IGMP status is Down
IGMP Querier IP address is 0.0.0.0
Current IGMP version is 2
Administrative IGMP robustness variable 2
Operational IGMP robustness variable 0
Administrative IGMP query interval is 125 seconds
Operational IGMP query interval is 0 seconds
Administrative IGMP max query response time is 10.0 seconds
Operational IGMP max query response time is 0.0 seconds
Administrative Last member query response interval is 1000 ms
Operational Last member query response interval is 0 ms
sh ip igmp snooping interface 20

Thx for your help.
