hwVlanFlowAccountEntry
1.3.6.1.4.1.2011.5.6.1.14.1
Describes the VLAN-based traffic statistics, including the numbers of the upstream bytes,
downstream bytes, upstream packets, downstream packets, upstream and downstream packets
in the ACL-based traffic statistics collection, discarded upstream packets, and discarded
downstream packets.
The indexes of this entry are hwVlanIndex (outer VLAN ID) and hwInnerVlanID (inner VLAN ID).
hwVlanIndex references the leaf in hwVlanMIBTable.
If hwInnerVlanID is -1, that means the InnerVLAN-based traffic statistics is not supported.
If hwVlanTrafficOccupiedTable is being used to query the traffic and bandwidth occupancy of
a VLAN, querying hwVlanFlowAccountTable fails.
