Description
A 64-bit counter of the number of packets
transmitted on this interface, including OAM
cells. This should be approximately the total
number of packets on all the VCs on this interface.
(If traffic stops for a few seconds, these numbers
should be exactly equal.)
A 64-bit counter of the bytes transmitted on this
interface, including OAM cells and AAL5 header
encapsulations (such as AAL5SNAP). This should
be approximately the total number of bytes
transmitted on each of the VCs.
The total number of packets that were not
transmitted because of any resource exhaustion
error. This does not necessarily imply an error,
because this counter includes
tx_wred_thresh_drops and
tx_wred_random_drops, as well as packet drops
due to complete buffer exhaustion on the SAR.
This should be equal to the sum of the number of
resource errors that occur on all the VCs.
The total number of packets that were not
transmitted because of any error other than
resource exhaustion, but not including no-vc
drops. This includes malformed packets, CRC
errors, and so on. This should be approximately
the total number of tx_other_errors that occur on
all the VCs on this interface.
The total number of WRED maximum threshold
drops on this interface. This counter is included in
the tx_total_resource_errs counter.
interface. This counter is included in the
tx_total_resource_errs counter.
The total number of packets reassembled on this
interface by the SAR, including OAM cells.
The total number of bytes reassembled on this
interface by the SAR, including AAL5
encapsulation bytes.

Comments
Packets output in the
show interface
command should have
the same value,
excluding OAM cells.
Output bytes in the
show interface
command should have
the same value,
excluding OAM cells.
Buffer exhaustion
should not occur if you
have not
oversubscribed the
queue thresholds on the
interface. See the
"Debugging
Unexpected TX Drops
on a VC" section on
