Traffic Passed
Left/Right Line Port
Number of frames sent to the Left/Right Line port from each of the
associated priority queues (described above). Note that each of these
counters has 24 bits, so it will roll over to 0 after reaching 16,777,215.
Note
: Only the packets transporting Ethernet frames are counted (i.e.
the "maintenance" packets are not included in these counts).
FPGA Drop Port
Number of frames sent to the FPGA's Drop port from each of the
associated priority queues (described above).
64
Note that these do not
necessarily get sent to the paddleboard since this is counted before
the “filtering” for D-PVLANs and QVLANs. Also note that each of these
counters has 24 bits, so it will roll over to 0 after reaching 16,777,215.
Clear Queue Counts
Clears traffic counters for all priority queues displayed in both
Passed
and
Lost
tabs.
Table 7 identifies the cases when a frame received on a local drop port should
increment a local "n-
" Line counter, depending on the frame‟s type, destination
address (DA) and status of the given DA entry in the local "WAN" and "LAN"
MAC Address tables.
64
The FPGA's Drop port is an internal port between FPGA and CPU. Therefore, in addition to
the traffic actually dropped through the unit's GMII port (interface to the paddleboard), these
counters also include traffic that may be discarded after the D-PVLAN and any QVLAN egress
filtering. Note that the D-PVLAN and QVLAN filtering does not affect the DA-known unicast
traffic.
