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.
