Parameters:
Name Description
queryinterval
<queryinterval-val>
This parameter is used to calculate the entry age out timer, when
no reports or queries are received on the entry. When the value of
this parameter multiplied by 10, it should be greater than the
Query Interval configured at the router. The time for which an
entry created at Igmpsnoop module exists, if no messages are
received for it is approximately (((QueryInterval*10)*Robustness)
+ Query Response Time received in Last Query)
Type: Modify -- Optional
Valid values: 1 - 0xff
anxioustimer
<anxioustimer-val>
This parameter specifies the maximum time (in seconds) before
which the IgmpSnoop module will forward all IGMP membership
reports received. It is started once, whenever the first
membership report is received for a group, to ensure that reports
are forwarded for a sufficiently long time, to take care of any lost
reports. The unit is seconds.
Type: Modify -- Optional
Valid values: 1 - 65535
v1hosttimer
<v1hosttimer-val>
This parameter specifies the maximum time (in seconds), for
which the IgmpSnooping module can assume that there are
Version 1 group members present, for the group for which this
timer is running. The unit of this parameter is seconds.
Type: Modify -- Optional
Valid values: 1 - 260
lastmembqryinterval
<lastmembqryinterval-v
al>
This parameter specifies the Last Member Query Interval that is
the Max Response Time inserted into Group-Specific Queries
sent in response to Leave Group messages, and is also the
amount of time between Group-Specific Query messages. The
value of this parameter may be tuned to modify the leave latency
of the network. A reduced value results in reduced time to detect
the loss of the last member of a group. The unit of this parameter
is one-tenth of second.
Type: Modify -- Optional
Valid values: 1 – 255
robustness
<robustness-val>
This parameter allows tuning for the expected packet loss on a
subnet. The IgmpSnooping module is robust to [RobustnessVar]
packet losses.
Type: Modify -- Optional
Valid values: 2 - 255
