revdistrib Enable |
Disable
It denotes whether reverse distribution filtering is
to be enforced for traffic in the receiving direction,
when both the links are active, for this aggregator
interface. If duplicate packets are expected on the
redundant links (if uplink aggregating device is
layer2 switch), Reverse distribution filtering may
be enabled. But if there is no chance of such
duplicate packets, or the duplicate packets need
not have a special handling, reverse distribution
filtering may be disabled.

Default value: enable
fallback Enable |
Disable
This specifies whether fallback is to happen for
aggregator interface, when a link goes down. As
fallback trigger leads to re-propagation of protocol
PDUs to the links based on the state of the links,
this may be enabled if re-propagation of protocol
PDUs is required for immediate restoration of peer
protocol state on uplink devices. If such a
treatment is not required and Protocol time out
may only be triggered for re-propagation, Fallback
trigger should be disabled.

Interface Index
This specifies the interface index used for the
Redundancy Aggregator type of interfaces. Valid
Value is aggr-0
Reverse Distribution
It denotes whether reverse distribution filtering is
to be enforced for traffic in the receiving direction,
when both the links are active, for this aggregator
interface. If duplicate packets are expected on the
redundant links (if uplink aggregating device is
layer2 switch) Reverse distribution filtering may be
enabled. But if there is no chance of such
duplicate packets or the duplicate packets need
not have a special handling reverse distribution
filtering may be disabled.
