set protocols igmp-snooping max-response-time


The set protocols igmp-snooping max-response-time command configures the maximum response time for an IGMP general query message or a group-specific query message.


Command Syntax

set protocols igmp-snooping max-response-time <max-response-time>


Parameter

Parameter

Description

max-response-time <max-response-time>

Specifies the maximum response time for an IGMP general query message or a group-specific query message. The value is an integer, in seconds, that ranges from 1 to 25.

The default value is 10.


Usage Guidelines

The maximum response time can be used to adjust the aging time of member ports. When the switch receives the report message from the downstream host, it starts the aging timer for the member port. The aging time is calculated using the following formula: Aging time = General query count × General query interval + Maximum response time. The set protocols igmp-snooping max-response-time command is used to configure the maximum response time in the above formula. The General query count can be configured using the set protocols igmp-snooping robustness-variable command. The General query interval can be configured using the set protocols igmp-snooping query-interval command.

When the aging time of the member port expires, this member port will be deleted from the Layer 2 forwarding table.

When the switch receives an IGMP report message on the dynamic member port, the aging time of the member port will be reset.

The maximum response time can be used to adjust the aging time of member ports when the switch receives an IGMP leave message from a host, for detail please refer to set protocols igmp-snooping last-member-query-count command.

NOTE:

  •   We recommend setting the value of Maximum response time smaller than the value of General query interval.
  •   The aging time takes effect only on dynamic member ports, however, the static member ports do not age.


Example

  •   Configure the maximum response time for IGMP general query message.
