Adding an interface to a multicast group

Modifying IGMP (V1 and V2) maximum response time

Maximum response time defines how long the device will wait for an IGMP (V1 and V2) response
from an interface before concluding that the group member on that interface is down and removing
the interface from the group. Possible values are 1 – 10. The default is 10.
To change the IGMP (V1 and V2) maximum response time, enter a command such as the following
at the global CONFIG level of the CLI.
BigIron RX(config)# ip igmp max-response-time 8
Syntax: [no] ip igmp max-response-time <num>
The <num> parameter specifies the number of seconds and can be a value from 1 – 10. The
default is 10.
Adding an interface to a multicast group
You can manually add an interface to a multicast group. This is useful in the following cases:
•
•
When you manually add an interface to a multicast group, the Brocade device forwards multicast
packets for the group but does not itself accept packets for the group.
You can manually add a multicast group to individual ports only. If the port is a member of a virtual
routing interface, you must add the ports to the group individually.
To manually add a port to a multicast group, enter a command such as the following at the
configuration level for the port.
BigIron RX(config-if-e10000-1/1)# ip igmp static-group 224.2.2.2
This command adds port 1/1 to multicast group 224.2.2.2.
To add a port that is a member of a virtual routing interface to a multicast group, enter a command
such as the following at the configuration level for the virtual routing interface.
BigIron RX(config-vif-1)# ip igmp static-group 224.2.2.2 ethernet 5/2
This command adds port 5/2 in virtual routing interface 1 to multicast group 224.2.2.2.
Syntax: [no] ip igmp static-group <ip-addr> [ethernet <slot>/<portnum>]
The <ip-addr> parameter specifies the group number.
The ethernet <slot>/<portnum> parameter specifies the port number. Use this parameter if the
port is a member of a virtual routing interface, and you are entering this command at the
configuration level for the virtual routing interface.
Manually added groups are included in the group information displayed by the following
commands:
•
•
586
Hosts attached to the interface are unable to add themselves as members of the group using
IGMP.
There are no members for the group attached to the interface.
show ip igmp group
show ip pim group
