QueryInterval
|
The frequency (in seconds) at which IGMP host query packets are transmitted on the interface. The range is from 1 to 65535. The default is 125.
|
Version
|
The version of IGMP that is configured on the interface. For IGMP to function correctly, all routers on a LAN must be configured to run the same version of IGMP on that LAN. Select IGMP version1 or version2 for ALL routers on the LAN.
|
QueryMaxResponseTime
|
The maximum response time (in seconds) advertised in IGMPv2 general queries on this interface. Smaller values allow a router to prune groups faster. This value for IGMPv1 is not configurable and has a default value of 10 seconds.
|
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 with a default value of 2. The default value of 2 means that one query per query interval may be dropped without the querier aging out.
|
LastMemQueryInt
|
The maximum response time inserted into group-specific queries sent in response to leave group messages; also the time between group-specific query messages. Increasing this parameter increases the time before aging hosts on the network. It also increases the number of retransmits of group-specific queries. The range is from 1 to 255. The default value is 1.
