Configuring IGMP Filtering
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 thi s mo de , 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:
•deny: Specifies that matching addresses are denied; this is the default condition.
•exit: Exits from igmp-profile configuration mode.
•no: Negates a command or sets its defaults.
•permit: Specifies that matching addresses are permitted.
•range: Specifies a range of IP addresses for the profile. Y o u can en ter a sing le IP addre ss or a rang e
with a start and an end address.
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:
To delete a profile, use the no ip igmp profile profile number global configuration command.
To delete an IP multicast address or range of IP multicast addresses, use the no range ip multicast
address IGMP profile configuration command.
IGMP profiles None defined
IGMP profile action Deny the range addresses
