Internet Group Multicast Protocol (IGMP)

The Internet Group Multicast Protocol (IGMP) is a communications protocol used by hosts and adjacent routers on IP networks. It is used to establish multicast group memberships. The host joins a multicast group by sending a join request message towards the network router, and responds to queries sent from the network router by dispatching a join report.

General notes:

  • In ArubaOS-CX IGMP snooping is disabled by default
  • IGMP v3 is used by default; supported configuration allows v2 and v3

Configuration commands

(switch(config)#)

interface vlan 1
igmp

Show commands to validate functionality

(switch(config)#)

show ip igmp-snooping vlan 1

Expected results

The show command should show IGMP enabled on the VLAN, but no IGMP querier set.
