everyone
Having trouble with multicast on cisco WS-C4948-10GE (MPC8540).
I have two switches running:
System image file is "bootflash:cat4000-i5k91s-mz.122-25.EWA9.bin" and System image file is "bootflash:cat4500-entservicesk9-mz.122-46.SG.bin"
Both suffers from the same problem. I've configure several ports with vlan 100 which has multicast. Then it floods multicast to all ports which has vlan 100 what consumes 50Mb/s of link bandwith.
Swtich-2#show ip igmp snooping
Vlan 100:
--------
IGMP snooping : Enabled
IGMPv2 immediate leave : Disabled
Explicit host tracking : Enabled
Multicast router learning mode : pim-dvmrp
