Configuring IGMP Profiles

To configure an IGMP profile, use the ip igmp profile global configuration command with a profile
number to create an IGMP profile and to enter IGMP profile configuration mode. From this mode, you
can specify the parameters of the IGMP profile to be used for filtering IGMP join requests from a port.
When you are in IGMP profile configuration mode, you can create the profile by using these commands:
•

The default is for the switch to have no IGMP profiles configured. When a profile is configured, if
neither the permit nor deny keyword is included, the default is to deny access to the range of IP
addresses.
Beginning in privileged EXEC mode, follow these steps to create an IGMP profile:
Command
Step 1 configure terminal
Step 2
ip igmp profile profile number
Step 3
permit | deny
Step 4

(Optional) Set the action to permit or deny access to the IP multicast
address. If no action is configured, the default for the profile is to deny
access.
Enter the IP multicast address or range of IP multicast addresses to
which access is being controlled. If entering a range, enter the low IP
multicast address, a space, and the high IP multicast address.
You can use the range command multiple times to enter multiple
addresses or ranges of addresses.
Return to privileged EXEC mode.
