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.
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-

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-

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.
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.
