Chapter 22 Configuring IGMP Snooping and MVR
Configuring IGMP Filtering and Throttling
Default IGMP Filtering and Throttling Configuration
shows the default IGMP filtering configuration.
When the maximum number of groups is in forwarding table, the default IGMP throttling action is to
deny the IGMP report. For configuration guidelines, see the
“Configuring the IGMP Throttling Action”
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:
•
deny
: Specifies that matching addresses are denied; this is the default.
•
exit
: Exits from igmp-profile configuration mode.
•
no
: Negates a command or returns to 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 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.
