Statically Configuring an Interface to Join a Group
Ports normally join multicast groups through the IGMP report message, but you can also statically
configure a host on an interface.
Beginning in privileged EXEC mode, follow these steps to add a port as a member of a multicast group.
SUMMARY STEPS
1. configure terminal
2. ip igmp snooping vlan
vlan-id
static
mac-address
interface
interface-id
3. end
4. show mac-address-table multicast [vlan
vlan-id
] [user | igmp-snooping] [count]
5. copy running-config startup-config
DETAILED STEPS
Command Purpose
