Parameters:
Name Description
portid <portid-val> This parameter specifies a bridge port for which IGMP Snooping
needs to be enabled or disabled.
Type: Modify -- Mandatory
Get -- Optional
Valid values: 1 - 194
status Enable | Disable This parameter specifies whether IGMP Snooping is to be
enabled on the port.
Type: Modify -- Optional
leavemode Normal | Fast
| FastNormal
This parameter specifies the Igmp Snooping Leave message
processing mode for the port. If the mode is set to 'Normal', the
Leave message is forwarded to the Querier. Then, based on the
Query received from Querier, the Leave processing is triggered.
If the mode is set to 'Fast', the port is immediately deleted from
that multicast group on Leave message reception and then the
Leave message is forwarded. The mode should be set to 'Fast'
for a port only if there is one host behind the port. This is
because if there are multiple hosts behind the port then it will
lead to traffic disruption for other hosts who might still be
listening to that multicast group. If the mode is set to
'FastNormal', the Leave message is forwarded and the Leave
processing is triggered immediately without waiting for any
trigger from the Querier. The 'FastNormal' mode, thus, saves the
delay (equal to the time taken for Leave message to reach router
and Querier processing time for it and the time taken for Query
to reach IGMP Snoop module) in Leave processing.
Type: Modify -- Optional
Valid values: op module) in Leave processing.
pktpriority
<pktpriority-val> | none
This parameter specifies the Egress Priority to be set in case the
Ethernet frames carrying IGMP packets sent over this port need
to be tagged by the control plane. In case the frame came
tagged, priority that came in the tagged frame will not be
changed. The configured priority will also be used for choice of
traffic class/Queue on outgoing interface whether the frame is
tagged . In case the bridge port is over an Aggregated ATM VC,
this will also be used to identify the VC, on which the packet is to
be sent. There is an additional support of invalid value for egress
priority in IGMP port info to indicate that the priority is not to be
forced on egress frame for this port.
