Group Query Interval - Supermicro SSE-G24-TG4 Configuration Manual

IGMP Snooping Configuration Guide
Immediate Leave – This configures the switch to consider the host leave immediately instead of sending
group specific query messages to look for other IGMP hosts on the port that received an IGMP leave
message.
These parameters can be configured as explained below.

1.7.1 Group Query Interval

Switches send a group specific query messages on the port that received an IGMP leave message.
Switches wait for the group query interval time to get a response from the hosts for its group specific
query messages. If they receive any host member report as a response, they will drop the leave message
received earlier on that port. If they do not receive any response from hosts for a group query interval
time, the switches will resend a query specific message based on the retry count. When the number of
times specified in the retry count is met without a response from any of the hosts, the switches will
remove the port from the group entry in the multicast forwarding table.
Users can configure this group query interval. The default group query interval is 2 seconds.
Follow the steps below to configure the group query interval.
Step Command
configure terminal
Step 1
Step 2 ip igmp snooping group-query-interval <timeout>
Step 3 end
Step 4 show ip igmp snooping globals
Step 5 write startup-config
The "no ip igmp snooping group-query-interval" command resets the group query interval
value to its default value of 2 seconds.
The example below shows the commands used to configure the group query interval time.
Configure the group query interval time as 5 seconds.
SMIS# configure terminal
SMIS(config)# ip igmp snooping group-query-interval 5
