Chapter 15 Configuring IGMP Snooping
Configuring IGMP Filtering and Throttling
This example shows how to create IGMP profile 4 allowing access to the single IP multicast address and
how to verify the configuration. If the action was to deny (the default), it would not appear in the
show
ip igmp profile
output display.
Switch(config)#
ip igmp profile 4
Switch(config-igmp-profile)#
permit
Switch(config-igmp-profile)#
range 229.9.9.0
Switch(config-igmp-profile)#
end
Switch#
show ip igmp profile 4
IGMP Profile 4
permit
range 229.9.9.0 229.9.9.0
Applying IGMP Profiles
To control access as defined in an IGMP profile, use the
ip igmp filter
interface configuration command
to apply the profile to the appropriate interfaces. You can apply IGMP profiles only to Layer 2 access
ports; you cannot apply IGMP profiles to routed ports or SVIs. You cannot apply profiles to ports that
belong to an EtherChannel port group. You can apply a profile to multiple interfaces, but each interface
can have only one profile applied to it.
Beginning in privileged EXEC mode, follow these steps to apply an IGMP profile to a switch port:
To remove a profile from an interface, use the
no ip igmp filter
profile number
interface configuration
command.
This example shows how to apply IGMP profile 4 to a port:
Switch(config)#
interface gigabitethernet0/2
Switch(config-if)#
ip igmp filter 4
Switch(config-if)#
end
Setting the Maximum Number of IGMP Groups
You can set the maximum number of IGMP groups that a Layer 2 interface can join by using the
ip igmp
max-groups
interface configuration command. Use the
no
form of this command to set the maximum
back to the default, which is no limit.
Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
interface
interface-id
Specify the physical interface, and enter interface configuration mode.
The interface must be a Layer 2 port that does not belong to an
EtherChannel port group.
Step 3
ip igmp filter
profile number
Apply the specified IGMP profile to the interface. The range is 1 to
4294967295.
Step 4
end
Return to privileged EXEC mode.
Step 5
show running-config interface
interface-id
Verify the configuration.
Step 6
copy running-config startup-config
(Optional) Save your entries in the configuration file.
