Multicast Filtering Commands 4

ip igmp max-resp-interval

This command configures the maximum response time advertised in IGMP queries. Use the no form of this command to restore the default.

Syntax

ip igmp max-resp-interval seconds no ip igmp max-resp-interval

seconds - The report delay advertised in IGMP queries. (Range: 1-255)

Default Setting

10 seconds

Command Mode

Interface Configuration (VLAN)

Command Usage

•The switch must be using IGMPv2 for this command to take effect.

•This command defines how long any responder (i.e., client or router) still in the group has to respond to a query message before the router deletes the group.

•By varying the Maximum Response Interval, you can tune the burstiness of IGMP messages passed on the subnet; where larger values make the traffic less bursty, as host responses are spread out over a larger interval.

•The number of seconds represented by the maximum response interval must be less than the Query Interval (page 4-236).

Example

The following shows how to configure the maximum response time to 20 seconds:

Console(config-if)#ip igmp max-resp-interval 20

Console(config-if)#

ip igmp version (4-238)

ip igmp query-interval(4-236)

ip igmp last-memb-query-interval

This command configures the last member query interval. Use the no form of this command to restore the default.

Syntax

ip igmp last-memb-query-interval seconds no ip igmp last-memb-query-interval

seconds - The report delay for the last member query. (Range: 1-255)

Default Setting

1 second
