4 Command Line Interface

Command Usage

The robustness value is used in calculating the appropriate range for other IGMP variables, such as the Group Membership Interval (ip igmp last-memb-query-interval, page 4-237),as well as the Other Querier Present Interval, and the Startup Query Count (RFC 2236).

Example

Console(config-if)#ip igmp robustval 3

Console(config-if)#

ip igmp query-interval

This command configures the frequency at which host query messages are sent. Use the no form to restore the default.

Syntax

ip igmp query-interval seconds no ip igmp query-interval

seconds - The frequency at which the switch sends IGMP host-query messages. (Range: 1-255)

Default Setting

125 seconds

Command Mode

Interface Configuration (VLAN)

Command Usage

•Multicast routers send host query messages to determine the interfaces that are connected to downstream hosts requesting a specific multicast service. Only the designated multicast router for a subnet sends host query messages, which are addressed to the multicast address 224.0.0.1.

•For IGMP Version 1, the designated router is elected according to the multicast routing protocol that runs on the LAN. But for IGMP Version 2, the designated querier is the lowest IP-addressed multicast router on the subnet.

Example

The following shows how to configure the query interval to 100 seconds:

Console(config-if)#ip igmp query-interval 100

Console(config-if)#

4-236
