Default
IGMP snooping and the with-proxy option are enabled by default, but forward-mcrouter-only option is
disabled by default.
Usage Guidelines
If a VLAN is specified, IGMP snooping is disabled only on that VLAN, otherwise IGMP snooping is
disabled on all VLANs.
If the switch is in the
forward-mcrouter-only
forward-mcrouter-only
not in the forward-mcrouter-mode, the command
has no effect.
To change the snooping mode you must disable IP multicast forwarding. Use the command:
disable ipmcforwarding
The with-proxy option can be used for troubleshooting purpose. It should be enabled for normal
network operation.
Enabling the proxy allows the switch to suppress the duplicate join requests on a group to forward to
the connected layer 3 switch. The proxy also suppresses unnecessary IGMP leave messages so that they
are forwarded only when the last member leaves the group.
Example
The following command disables IGMP snooping on the VLAN accounting:
disable igmp snooping accounting
