|
IfIndex
|
The interface on which IGMP is enabled.
|
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.
|
Status
|
The IGMP row status. When an interface has been assigned an IP address and DVMRP is enabled, status is shown as active. Otherwise, it is shown as notInService.
|
Version
|
The version of IGMP that is configured on the interface. For IGMP to function correctly, you must configure all routers on a LAN to run the same version of IGMP on that LAN. The default is version 2 in -B hardware and version 1 in -A hardware.
|
OperVersion
|
The version of IGMP that is configured on the LAN.
|
Querier
|
The address of the IGMP querier on the IP subnet to which the interface is attached.
|
QueryMaxResponseTime
|
The maximum response time (in seconds) advertised in IGMPv2 queries on this interface. Smaller values allow a router to prune groups faster.
|
WrongVersionQueries
|
The number of queries received with an IGMP version that does not match the interface. IGMP requires that all routers on a LAN be configured to run the same version of IGMP. If any queries are received with the wrong version, it indicates a version mismatch.
|
Joins
|
The number of times a group membership has been added on this interface; that is, the number of times an entry for this interface has been added to the cache table. This number gives an indication of the amount of IGMP activity over time.
|
Robustness
Lossy?
|
This parameter allows tuning for the expected packet loss of a network. If a network is expected to be lossy, the robustness value should be increased. The range is from 2 to 255. The default value is 2.
|
LastMembQueryIntvl
|
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 1to 255. The default value is 10.
|
igmpInterfaceOtherQuerierPresentTimeout
|
A timeout interval.
