Changing global IP multicast parameters
Modifying IGMP (V1 and V2) 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 1 – 7200 seconds and the default value is 140
seconds.
To define an IGMP (V1 and V2) membership time of 240 seconds, enter the following.
TurboIron(config)#ip igmp group-membership-time 240
Syntax: ip igmp group-membership-time <1-7200>
Modifying IGMP (V1 and V2) maximum response time
Maximum response time defines how long the Layer 3 Switch 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.
TurboIron(config)#ip igmp max-response-time 8
Syntax: [no] ip igmp max-response-time
The parameter specifies the number of seconds and can be a value from 1 – 10. The
default is 10.
NOTE
Adding an interface to a multicast group
You can manually add an interface to a multicast group. This is useful in the following cases:
• 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.
When you manually add an interface to a multicast group, the 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.
TurboIron(config-if-1)#ip igmp static-group 224.2.2.2
This command adds port 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.
TurboIron(config-vif-1)#ip igmp static-group 224.2.2.2 ethernet 2
This command adds port 2 in virtual routing interface 1 to multicast group 224.2.2.2.
Syntax: [no] ip igmp static-group [ethernet ]
The parameter specifies the group number.
