Command

Description

 

 

timeout <1-255>

Sets the Maximum Response Time (MRT) for IGMP hosts. MRT is one of the

 

parameters used to determine the age out period of the IGMP hosts.

 

Increasing the timeout increases the age out period.

 

The range is from 1 to 255 seconds. The default is 10 seconds

 

 

mrto <1-600>

Configures the age-out period for the IGMP Mrouters in the Mrouter table. If

 

the switch does not receive a General Query from the Mrouter for mrto

 

seconds, the switch removes the multicast router from its Mrouter table.

 

The range is from 1 to 600 seconds. The default is 255 seconds.

 

 

qintrval <1-600>

Sets the IGMP router query interval. The range is 1-600 seconds. The default

 

value is 125.

 

 

robust <2-10>

Configures the IGMP Robustness variable, which allows you to tune the

 

switch for expected packet loss on the subnet. If the subnet is expected to be

 

lossy (high rate of packet loss), then increase the value. The default value is

 

2.

 

 

aggr disableenable

Enables or disables IGMP Membership Report aggregation.

 

 

srcip <IP address>

Configures the source IP address used as a proxy for IGMP Group Specific

 

Queries.

 

 

add <1-4095>

Adds the VLAN to IGMP Snooping.

 

 

rem <1-4095>

Removes the VLAN from IGMP Snooping.

 

 

clear

Removes all VLANs from IGMP Snooping.

 

 

fastlv <1-4095> disableenable

Enables or disables FastLeave processing. FastLeave allows the switch to

 

immediately remove a port from the IGMP port list, if the host sends a Leave

 

message, and the proper conditions are met. This command is disabled by

 

default.

 

 

ena

Enables IGMP Snooping.

 

 

dis

Disables IGMP Snooping.

 

 

cur

Displays the current IGMP Snooping parameters.
