indicates that Proxy Arp request can be received through this port.
This field can be enabled only on bridge port created over ethernet or
aggregator interface. Before enabling this field user should create a
filter rule with rule action as Copy to Control and rule description as
IPOE_CONTROL and map it to all those interfaces through which user
wants to receive proxy arp requests.
Sensed IfIndex This specifies the sensed interface index corresponding to the bridge
port. This field is used to determine the stack sensed for this bridge
port in the auto sensing scenario. This field cannot be modified. If the
oper status of the bridge port is 'enable' or 'disable' then the value of
this field gives the interface index on which the bridge port is currently
stacked. If the oper status is 'dormant' and the value of this field is
other than '-', then it represents the last interface index on which the
bridge port had been stacked.
ArpTStatus This specifies whether ARP translation will be done on the ARP
packets received/transmitted on this port. When enabled, ARP
source MAC address of the incoming ARP packets (both
request/reply) will be changed to virtual MAC address (if applicable)
and the ARP target MAC address of the outgoing ARP reply packets
will be changed to the original host MAC address (if applicable).
Directed ARP status This specifies whether the ARP packets received on this bridge port
are to be directed to a single port using (VLANId, IP address) to
bridge port mapping learnt using DRA. This field can be enabled only
on the NET side bridge port. This attribute is effective in conjunction
with the attribute 'gsv dot1qVlanStaticDirectedARP' of
'Dot1qVlanStatic' 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.
Port Type This field specifies whether the port is trusted or not. This information
is used by some of the control plane applications to send packet on
trusted ports, in case the application fails to uniquely determine a port.
