snooping or proxy reporting for the IGMP messages,

 

 

 

 

 

received on a Vlan. Here the Vlan which is being

 

 

 

 

 

referred is the one on which learning will happen. It will

 

 

 

 

 

be multicast vlan, if "Multicast Vlan option" is enabled.

 

 

 

 

 

 

 

 

 

 

Igmpsnoop ingress Priority

This parameter specifies the ingress priority to be forced

 

 

 

 

 

on the incoming frame. If the ingress priority field has

 

 

 

 

 

valid value, then that value will be used for traffic class

 

 

 

 

 

determination and packet priority. If valid egress priority

 

 

 

 

 

is configured for a port, then egress priority shall override

 

 

 

 

 

the ingress priority. In addition, there is support of invalid

 

 

 

 

 

value for ingress priority to indicate that the priority is not

 

 

 

 

 

to be forced on ingress frame for this port.Here the Vlan

 

 

 

 

 

which is being referred is the one on which learning shall

 

 

 

 

 

happen. It will be multicast vlan, if "Multicast Vlan option"

 

 

 

 

 

is enabled.

 

 

 

 

 

 

 

 

 

 

Directed ARP status

This specifies whether ARP packets received on this

 

 

 

 

 

VLAN are to be directed to a single port using (VLANId,

 

 

 

 

 

IP address) to bridge port mapping learnt using DRA.

 

 

 

 

 

This attribute is effective in conjunction with the attribute

 

 

 

 

 

'gsvDot1dPortDirectedARP' of 'Dot1dBasePortExtTable'

 

 

 

 

 

MO. ARP packets are to be directed as mentioned

 

 

 

 

 

above, only if both the flags are enabled. If any of the

 

 

 

 

 

two is disabled, the ARP packets will be forwarded as

 

 

 

 

 

per the normal bridging flow.

 

 

 

 

 

 

 

 

 

 

DARPFailedHandling

This specifies the action to be taken on an ARP packet

 

 

 

 

 

received on this VLAN for which it is not possible to

 

 

 

 

 

determine a single port using (VLANId, IP address) to

 

 

 

 

 

bridge port mapping learnt using DRA. If the value is

 

 

 

 

 

drop, the ARP packet will be dropped. If the value is

 

 

 

 

 

Transparent Forwarding, the ARP packet will be

 

 

 

 

 

forwarded as per the normal bridging. If the value is

 

 

 

 

 

FloodTrustedPorts, the ARP packet will be forwarded as

 

 

 

 

 

per the normal bridging, but only on ports that are

 

 

 

 

 

trusted.

 

 

 

 

 

 

 

 

 

 

DRA Bcast To Ucast

This Parameter is used to configure whether DHCP

 

 

 

 

 

broadcast packet received for this vlan will be converted

 

 

 

 

 

to unicast packet or not.

 

 

 

 

 

 

 

 

 

 

BNG MAC address

This is used to configure BNG Mac address of this

 

 

 

 

 

VLAN. If VLAN is configured to convert DHCP broadcast

 

 

 

 

 

packets to Unicast packets,then this MAC address is

 

 

 

 

 

used as destination MAC address.
