IGMP debug commands

The Internet Group Management Protocol (IGMP) allows an IPv4 system to communicate IP
multicast group membership information to its neighboring routers. The routers in turn limit the
multicast of IP packets with multicast destination addresses to only those interfaces on the router
that are identified as IP multicast group members.

The following commands display the information related to IGMP debugging.

debug ip igmp add-del-oif

Syntax: [no] debug ip igmp add-del-oif

This command displays information about the addition or deletion of the outgoing interfaces (OIFs).

Brocade# debug ip igmp add-del-oif

add-del-oif enabled

Brocade# debug ip igmp show

igmp debug-enable-any = 1

debug ip igmp add-del-oif is enabled

Brocade# debug ip igmp
