Label Description
Interface Specifies the interfaces that participates in the IGMP protocol.
Adm
Admin Status
Displays the administrative state for the IGMP protocol on this
interface.
Oper
Oper Status
Displays the current operational state of IGMP protocol on the
interface.
Querier Displays the address of the IGMP querier on the IP subnet to which
the interface is attached.
Querier Up Time Displays the time since the querier was last elected as querier.
Querier Expiry
Timer
Displays the time remaining before the querier ages out. If the que-
rier is the local interface address, the value will be zero.
Cfg/Opr Version
Admin/Oper ver-
sion
Cfg — The configured version of IGMP running on this interface.
For IGMP to function correctly, all routers on a LAN must be con-
figured to run the same version of IGMP on that LAN.
Opr. The operational version of IGMP running on this interface.
If the cfg value is 3 but all of the routers in the local subnet of this
interface use IGMP version v1 or v2, the operational version will
be v1 or v2.
Num Groups The number of multicast groups which have been learned by the
router on the interface.
Policy Specifies the policy that is to be applied on the interface.
Group Address Specifies the IP multicast group address for which this entry con-
tains information.
Up Time Specifies the time since this source group entry got created.
Last Reporter Specifies the IP address of the source of the last membership report
received for this IP Multicast group address on this interface. If no
membership report has been received, this object has the value
0.0.0.0.
Mode The mode is based on the type of membership report(s) received on
the interface for the group. In the 'include' mode, reception of pack-
ets sent to the specified multicast address is requested only from
those IP source addresses listed in the source-list parameter of the
IGMP 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.
V1 Host Timer The time remaining until the local router will assume that there are
no longer any IGMP version 1 members on the IP subnet attached
to this interface. Upon hearing any IGMPv1 Membership Report,
this value is reset to the group membership timer. While this time
remaining is non-zero, the local router ignores any IGMPv2 Leave
messages for this group that it receives on this interface.
