Cuda 12000 IP Access Switch CLI Reference Guide
ip igmp 187
ip igmp
Configures the interface for IGMP communications.
Mode
interface
Syntax
ip igmp {join-group <group-address> | query-interval <seconds> |
query-max-response-time <seconds> | version {2 | 1 | v2_only} |
robustness <value> | router | last-query-interval <seconds>}
Arguments
join-group <group-address> Specifies the Class D IP address of the multicast group (for
example, 225.3.2.2) that the Cuda 12000 joins on the interface.
query-interval <seconds> Specifies the frequency, in seconds, that the Cuda 12000
transmits IGMP host query packets on this particular interface.
The default is 125 seconds with a range of 10 to 65535 seconds.
query-max-response-time
<seconds>
Specifies the maximum number of seconds that the Cuda 12000
waits for a response to an IGMP Query message before deleting
the group. The default is 10 seconds with a range of 1 to 25
seconds.
version {2 | 1 | v2_only} Version of IGMP running on this particular interface. For IGMP to
function properly, all routers on a network must be configured
to run the same version of IGMP. The default is 2 and the
possible values are:
■ 2 – Version 2. If the Cuda 12000 encounters another host or
router on the network using Version 1, the Cuda 12000
reverts back to using Version 1.
■ 1 – Version 1.
■ v2_only – Version 2 only. If the Cuda 12000 encounters
another host or router on the network using Version 1, the
Cuda 12000 continues to run Version 2.
robustness <number> Allows you to compensate for the expected packet loss on a
subnet. Increase the value if you expect the loss to be high. The
default is 2 and the range is 1 to 255.
