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.

 

 

IGMP PacketsPrio'

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.

 

 

MaxGroupAllowed

This parameter controls the no. of simultaneous channels that can

 

be received by this port

 

 

Querier Status

This parameter controls whether a port can become querier

 

 

McastVlan Status

This parameter controls the status of Multicast Vlan option on a

 

port

 

 

No McastVlan Match

This parameter specifies the action to be taken when multicast

Action

vlan can not be determined for a port where multicast vlan option

 

is enabled Possible action values will be :Drop, Transparently

 

forward, and Learn based on ingress vlan

 

 

Caution:

zAn entry in this table shall not be applicable for a bridge port created over the PPPoE interface.
