Description

 

 

 

VLAN Index

 

The VLAN id for this VLAN. In devices supporting "Shared Vlan for

 

 

multicast" capability, the information for a multicast MAC address is

 

 

shared across VLANS. Hence, vlanid is not required and is passed

 

 

as zero. In devices supporting "Independent Vlan for multicast"

 

 

capability. Each vlan can have its own information for a multicast

 

 

MAC address. Hence, VLAN id is a mandatory parameter and a

 

 

valid value of vlanid must be passed. For No Vlan case VLAN id is

 

 

not required. When Vlan transparency feature is supported, the

 

 

valid range for vlanid also includes 4097. In case of "Shared Vlan

 

 

Multicast also there shall always be a seperate entry for 4097 if the

 

 

VLAN with that VLAN Id is created. VLAN here means the 802.1q

 

 

Vlan in case of Native Vlan mode and Virtual Vlan in case of

 

 

Stacked Vlan Mode.

 

 

 

Mac Address

 

The destination Group MAC address in a frame, to which this

 

 

entry's filtering information applies

 

 

 

Egress ports

 

The complete set of bridge ports, in this VLAN, to which frames

 

 

destined for this Group MAC address are currently being explicitly

 

 

forwarded. This does not include ports for which this address is

 

 

only implicitly forwarded, in the dot1qForwardAllPorts list.

 

 

 

Group Learnt

 

The subset of bridge ports in EgressPorts, which were learned by

 

 

GMRP or some other dynamic mechanism, in this Filtering

 

 

database.
