DRAFT: BROCADE CONFIDENTIAL

Configuring IGMP snooping querier

If your multicast traffic is not routed because Protocol-Independent Multicast (PIM) and IGMP are

not configured, use the IGMP snooping querier in a VLAN.

IGMP snooping querier sends out IGMP queries to trigger IGMP responses from switches that wish

to receive IP multicast traffic. IGMP snooping listens for these responses to map the appropriate

forwarding addresses.

Refer to the CEE Command Reference for complete information about the commands in this

section.

Use the following procedure to configure the IGMP snooping querier.

1. Enter the configure terminal command to access global configuration mode.

2. Activate the default IGMP querier functionality for the VLAN.

Example

switch(conf-if-vl-25)#ip igmp snooping querier enable vlan 25

3. Activate IGMP querier functionality for the VLAN.

The valid range is 1 to 18000 seconds. The default is 125 seconds.

Example

switch(config)#ip igmp query-interval 125

4. Set the last member query interval.

The valid range is 1000 to 25500 milliseconds. The default is 1000 milliseconds.

Example

switch(config)#ip igmp last-member-query-interval 1000

5. Set the Max Response Time (MRT).

The valid range is 1 to 25 seconds. The default is 10 seconds.

Example

switch(config)#ip igmp query-max-response-time 10

Monitoring IGMP

Monitoring the performance of your IGMP traffic allows you to diagnose any potential issues on

your switch. This helps you utilize bandwidth more efficiently by setting the switch to forward IP

multicast traffic only to connected hosts that request multicast traffic.

Refer to the CEE Command Reference for complete information about the commands in this

section.

Use the following procedure to monitor IGMP snooping on a CEE/FCoE switch.

1. Enter the enable command to access Privileged EXEC mode.

2. Enter the show ip igmp groups command to display all information on IGMP multicast groups

for the switch.
