Configuring IGMP Snooping Chapter 18 Configuring IGMP Snooping and MVR • When administratively enabled, the IGMP snooping querier moves to the nonquerier state if it detects the presence of a multicast router in the network. • When it is administratively enabled, the IGMP snooping querier moves to the operationally disabled state under these conditions: - IGMP snooping is disabled in the VLAN. - PIM is enabled on the SVI of the corresponding VLAN. Beginning in privileged EXEC mode, follow these steps to enable the IGMP snooping querier feature in a VLAN: Command Purpose Step 1 configure terminal Enter global configuration mode. Step 2 ip igmp snooping querier Enable the IGMP snooping querier. Step 3 ip igmp snooping querier address ip_address (Optional) Specify an IP address for the IGMP snooping querier. If you do not specify an IP address, the querier tries to use the global IP address configured for the IGMP querier. Note The IGMP snooping querier does not generate an IGMP general query if it cannot find an IP address on the switch. Step 4 ip igmp snooping querier query-interval (Optional) Set the interval between IGMP queriers. The range is 1 to interval-count 18000 seconds. Step 5 ip igmp snooping querier tcn query [count (Optional) Set the time between Topology Change Notification count | interval interval] (TCN) queries. The count range is 1 to 10. The interval range is 1 to 255 seconds. Step 6 ip igmp snooping querier timer expiry timeout (Optional) Set the length of time until the IGMP querier expires.The range is 60 to 300 seconds. Step 7 ip igmp snooping querier version version (Optional) Select the IGMP version number that the querier feature uses. Select 1 or 2. Step 8 end Return to privileged EXEC mode. Step 9 show ip igmp snooping vlan vlan-id (Optional) Verify that the IGMP snooping querier is enabled on the VLAN interface. The VLAN ID range is 1 to 1001 and 1006 to 4094. Step 10 copy running-config startup-config (Optional) Save your entries in the configuration file. This example shows how to set the IGMP snooping querier source address to 10.0.0.64: Switch# configure terminal Switch(config)# ip igmp snooping querier 10.0.0.64 Switch(config)# end This example shows how to set the IGMP snooping querier maximum response time to 25 seconds: Switch# configure terminal Switch(config)# ip igmp snooping querier query-interval 25 Switch(config)# end This example shows how to set the IGMP snooping querier timeout to 60 seconds: Switch# configure terminal Switch(config)# ip igmp snooping querier timeout expiry 60 Switch(config)# end 18-14 Cisco Catalyst Blade Switch 3020 for HP Software Configuration Guide OL-8915-01
