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.
