groupCompatMode Is used in order for routers to be compatible with older version routers. MLDv2 hosts MUST operate in version 1 and version 2 compatibility modes. MLDv2 hosts MUST keep state per local interface regarding the compatibility mode of each attached network. A host's compatibility mode is determined from the Host Compatibility Mode variable which can be in one of two states: MLDv1 or MLDv2. This variable is kept per interface and is dependent on the version of General Queries heard on that interface as well as the Older Version Querier Present timers for the interface

groupExpiryTime Indicates the minimum amount of time remaining before this entry will be aged out

Displayed(tab/group)=Group Expiry Time

groupMode Indicates the type of membership report(s) received on the interface for the group. In the 'include' mode, reception of packets sent to the specified multicast address is requested only from those IP source addresses listed in the source-list parameter of the MLD membership report. In 'exclude' mode, reception of packets sent to the given multicast address is requested from all IP source addresses except those listed in the source-list parameter.

Displayed(tab/group)=Group Mode

groupType Indicates how this group entry was learned. If this group entry was learned by the MLD, it will be set to 'dynamic'. For statically configured groups, the value will be set to 'static'.

groupUpTime Indicates the time elapsed since this entry was created

type=long
access=read-only
minimum=0
maximum=2147483647
Displayed(tab/group)=Group Up Time

groupVer1HostTimer Indicates the time remaining until the local router will assume that there are no longer any MLD version 1 members on the IP subnet attached to this interface. Upon hearing any MLDv1 Membership Report, this value is reset to the group membership timer. While this time remaining is non-zero, the local router ignores any MLDv2 Leave messages for this group that it receives on this interface.

type=long
access=read-only
minimum=0
maximum=2147483647
Displayed(tab/group)=Version One Host Timer

groupVer2HostTimer Indicates the time remaining until the local router will assume that there are no longer any MLD version 2 members on the IP subnet attached to this interface

type=long
access=read-only

maximum=2147483647
Displayed(tab/group)=Version Two Host Timer
