QueryInterval
|
The frequency (in seconds) at which IGMP host query packets are transmitted on the interface. The range is from 1 to 65535, and the default is 125.
|
QueryMaxResponseTime
|
The maximum response time (in 1/10 seconds) advertised in IGMPv2 general queries on this interface. This value is can not be configured for IGMPv1.
Smaller values allow a router to prune groups faster. The range is from 0 to 255, and the default is 100 tenth seconds (equal to 10 seconds).
Note: This value must be less than the QueryInterval.
|
Robustness
|
This parameter allows tuning for the expected packet loss of a network. This value is equal to the number of expected query packet losses per serial query interval, plus 1. If a network is expected to lose query packets, the robustness value should be increased.
The range is from 2 to 255, and the default is 2. The default value of 2 means that one query per query interval may be dropped without the querier aging out.
|
LastMembQueryIntvl
|
The maximum response time (in 1/10 seconds) that is inserted into group-specific queries sent in response to leave group messages. It is also the time between group-specific query messages. This value can not be configured for IGMPv1.
Decreasing the value reduces the time to detect the loss of the last member of a group. The range is from 0 to 255, and the default is 10 tenth seconds. Nortel Networks recommends configuring this parameter to values higher than 3. If a fast leave process is not required, Nortel recommends values above 10. (The value 3 is equal to 0.3 of a second and 10 is equal to 1.0 second).
|
Version
|
The version of IGMP (1, 2 or 3) that you want to configure on this interface. For IGMP to function correctly, all routers on a LAN must use the same version. The default is version 2.
|
FastLeaveEnable
|
Enables fast leave on the interface.
|
StreamLimitEnable
|
Enables stream limitation on this interface.
|
Maximum Number of Stream
|
Sets the maximum number of streams allowed on this interface. The range is from 0 to 65535, and the default is 4.
|
Current Number of Stream
|
Displays the current number of streams. This is a read-only value.
