Configuring IGMP Filtering
Configuring IGMP Profiles
To configure an IGMP profile and to enter IGMP profile configuration mode, use the ip igmp profile
global configuration command. From the IGMP profile configuration 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 apply these keywords:
• deny—Specifies that matching addresses are denied (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. You can enter a single IP address or a range
with starting and ending addresses.
By default, no IGMP profiles are configured. When a profile is configured with neither the permit nor
the deny keyword, the default is to deny access to the range of IP addresses.
To create an IGMP profile for a port, perform this task:

Command Purpose
Step 1
Switch# configure terminal

the profile is to deny access.
Step 4
Switch(config-igmp-profile)# range ip
multicast address
Enters 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.
Use the range command multiple times to enter multiple
addresses or ranges of addresses.
Step 5
Switch(config-igmp-profile)# end
Returns to privileged EXEC mode.
Step 6
Switch# show ip igmp profile profile-number
Verifies the profile configuration.
