/cfg/l3/igmp/snoop
IGMP Snooping Configuration
IGMP Snooping allows the switch to forward multicast traffic only to those ports that
request it. IGMP snooping prevents multicast traffic from being flooded to all ports. The
switch learns which server hosts are interested in receiving multicast traffic, and forwards it
only to ports connected to those servers.
Table 6-80 describes the commands used to configure IGMP Snooping.

Command Syntax and Usage
igmpv3
Displays the IGMP version 3 Menu. To view menu options, see page 284.
mrto <1-600 seconds>

is reached, the switch removes the multicast router from its IGMP table, if the proper conditions
are met. The range is from 1 to 600 seconds. The default is 255 seconds.
aggr enable|disable
Enables or disables IGMP Membership Report aggregation.
srcip <IP address (such as, 192.4.17.101)>
Configures the source IP address used as a proxy for IGMP Group Specific Queries.
add <VLAN number (1-4094)>
Adds the selected VLAN(s) to IGMP Snooping.
rem <VLAN number (1-4094)>
Removes the selected VLAN(s) from IGMP Snooping.
