Table 112 igmpsnoop Command Summary
COMMAND DESCRIPTION P
switch igmpsnoop show Displays the IGMP mode (proxy, snooping or disabled). M/L
switch igmpsnoop enable
<proxy|snooping> [v2|v3]
Turns on IGMP proxy or snooping and, optionally, specifies the
IGMP version.
Use proxy to have the device use IGMP proxy. Use snooping to
have the device passively learn multicast groups.
If you select IGMPv2 (v2), the device discards IGMPv3 packets.
This provides better security if none of the devices in the
network use IGMPv3. If you select IGMPv3 (v3), the device
recognizes both IGMPv2 and IGMPv3.

switch igmpsnoop disable Turns off IGMP proxy or snooping. H/H
