Creating a static IGMP group

You can configure one or more physical ports to be a permanent (static) member of an IGMP group
based on the range or count.

To configure two static groups starting from 226.0.0.1, enter either this command:

Device(config)# interface ethernet 1/5

Device(config-if-e1000-1/5)# ip igmp static-group 226.0.0.1 count 2

Or this command:

Device(config)# interface ethernet 1/5

Device(config-if-e1000-1/5)# ip igmp static-group 226.0.0.1 to 226.0.0.2

Syntax: [no] ip igmp static-group ip-address [ count count-number | to ip-address ]

Enter the IP address of the static IGMP group for ip-address. The count-number range is 2-256.

To configure two static groups on virtual ports starting from 226.0.0.1, enter either this command:

Device(config)# interface ethernet 1/5

Device(config-if-e1000-1/5)# ip igmp static-group 226.0.0.1 count 2 ethernet 1/5

Or this command:

Device(config)# interface ve 10

Device(config-vif-10)# ip igmp static-group 226.0.0.1 to 226.0.0.2 ethernet 1/5

Syntax: [no] ip igmp static-group ip-address [ count count-number | to ip-address ] ethernet slot-
number

Enter the IP address of the static IGMP group for ip-address. The count-number range is 2-256.

Enter the ID of the physical port of the VLAN that will be a member of the group for ethernet slot-
number.

NOTE
IGMPv3 does not support static IGMP group members.

NOTE
Static IGMP groups are supported only in Layer 3 mode.

Setting the query interval

The IGMP query interval period defines how often a switch will query an interface for group
membership. Possible values are 2-3600 seconds and the default value is 125 seconds, but the value
you enter must be a little more than twice the group membership time.

To modify the default value for the IGMP query interval, enter the following.

device(config)# ip igmp query-interval 120

Syntax: [no] ip igmp query-interval 2-3600

The interval must be a little more than two times the group membership time.
