IfIndex
|
Indicates the interface on which IGMP is enabled.
|
QueryInterval
|
Indicates the frequency (in seconds) at which IGMP host query packets
are transmitted on the interface. Ensure that the robustness value
is the same as the configured value on the multicast router (IGMP
querier). The range is from 1–65535, and the default is 125.
|
Status
|
Indicates whether the interface is active. The interface becomes
active if IGMP forwarding ports exist on the interface. If the VLAN
has no port members or if all of the port members are disabled, the
status is notInService.
|
Version
|
Indicates the version of IGMP (1, 2, or 3) configured on this interface.
For IGMP to function correctly, all routers on a LAN must use the
same version. The default is version 2.
|
OperVersion
|
Indicates the version of IGMP currently running on this interface.
|
Querier
|
Indicates the address of the IGMP querier on the IP subnet to which
this interface attaches.
|
QueryMaxResponseTime
|
Indicates the maximum response time (in 1/10 seconds) advertised
in IGMPv2 general queries on this interface. This field is a read-only
field on the Ethernet Routing Switch 5000 Series .
|
WrongVersionQueries
|
Indicates the number of queries received with an IGMP version that
does not match the interface. All routers on a LAN must run the same
version of IGMP. If queries are received with the wrong version, it
indicates a version mismatch.
|
Joins
|
Indicates the number of times a group membership is added on this
interface; that is, the number of times an entry for this interface
is added to the cache table. This number gives an indication of the
amount of IGMP activity over time.
|
Robustness
|
Specifies tuning for the expected packet loss of a network. This
value is equal to the number of expected query packet losses for each
serial query interval, plus 1. If you expect a network to lose query
packets, you must increase the robustness value. Ensure that the robustness
value is the same as the configured value on the multicast router
(IGMP querier). The range is from 2 to 255, and the default is 2.
The default value of 2 means that one query for each query interval
can be dropped without the querier aging out.
|
LastMembQueryIntvl
|
Configures the maximum response time (in tenths of a second) that
is inserted into group-specific queries sent in response to leave
group messages. This parameter is also the time between group-specific
query messages. You cannot configure this value for IGMPv1. Decreasing
the value reduces the time to detect the loss of the last member of
a group. The range is from 0–255, and the default is 10 tenths of
seconds. Avaya recommends that you configure this parameter to values
higher than 3. If a fast leave process is not required, Avaya recommends
values above 10. (The value 3 is equal to 0.3 of a second, and 10
is equal to 1.0 second.)
|
RouterAlertEnable
|
When enabled, this parameter instructs the router to ignore IGMP
packets that do not contain the router alert IP option. When disabled
(default setting), the router processes IGMP packets regardless of
whether the router alert IP option is set or not. To maximize your
network performance, Avaya recommends that you configure this parameter
according to the version of IGMP currently in use:
IGMPv1—Disable
IGMPv2—Enable
IGMPv3—Enable
|
SendQuery
|
Indicates whether to send query.
|
FlushAction
|
Flushes the specified table type:
