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:
