Description

The following KB for Juniper EX/QFX Series Switches addresses how to configure all VLANs under 'protocols igmp-snooping'.

Symptoms

You want to configure IGMP snooping on all VLANs on devices with ELS support but the keyword "all" is not working.

Solution

Previously, IGMP snooping could be configured on all VLANs on legacy switches (EX2200, EX3300, EX4200, EX4500, etc.), with the command 'set protocols igmp-snooping vlan all'. Now, you must explicitly configure IGMP snooping on a VLAN for newer devices that support ELS with 'set protocols igmp-snooping vlan <name>'.
