Creating a static IGMP group
To configure a physical port to be a permanent (static) member of an IGMP group, enter the
following commands.
Brocade(config)# interface ethernet 1/5
Brocade(config-if-e1000-1/5)# ip igmp static-group 224.10.1.1
Syntax: [no] ip igmp static-group ip-address
Enter the IP address of the static IGMP group for ip-address.
To configure a virtual port to be a permanent (static) member of an IGMP group, enter the following
commands.
Brocade(config)# interface ve 10
Brocade(config-vif-10)# ip igmp static-group 224.10.1.1 ethernet 1/5
Syntax: [no] ip igmp static-group ip-address ethernet slot-number/port-number
Enter the IP address of the static IGMP group for ip-address.
Enter the ID of the physical port of the VLAN that will be a member of the group for ethernet
slot-number/port-number.
NOTE
IGMPv3 does not support static IGMP group members.
NOTE
IGMPv3 is not supported for groups with L2 Multicast CPU protection enabled.
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.
Brocade(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.
Setting the group membership time
Group membership time defines how long a group will remain active on an interface in the absence
of a group report. Possible values are from 5 – 26000 seconds and the default value is 260
seconds.
To define an IGMP membership time of 240 seconds, enter the following.
Brocade(config)# ip igmp group-membership-time 240
Syntax: [no] ip igmp group-membership-time 5-26000
