Description
Total ATM cells received on this port minus
idle cells.
Total ATM cells received on this port for
which no Virtual Channel Identifier (VCI)
was set-up.
Total ATM cells with a payload type
supporting CRC10 (Cyclic Redundancy
Check) that failed CRC10 validation.
Total AAL5 frames that failed CRC32 trailer
validation.
Total AAL5 frames received on this port
that had a source LEC ID that matched the
receiving LEC ID.
Total AAL5 frames that could not be re-
assembled due to resource exhaustion.
Total AAL5 frames received on this port
with an error in the AAL5 trailer.
Total AAL5 frames dropped because the
sending station set the trailer size to zero.
Total AAL5 frames dropped because the
frame length exceeded 11532 octets.
Total AAL5 frames dropped due to errors in
the frame tag header (LLC (Logical Link
Control) encapsulation header).
Total AAL5 frames dropped for timeout.
Total Ethernet frames received over ATM
and forwarded to the switch.
Total Ethernet frames received over ATM
but dropped for Queue overflow.
Total Ethernet frames received over ATM,
but dropped for resource exhaustion.
AAL5 frames received over ATM and
directed to the uplink CPU.
AAL5 frames received over ATM intended
for the uplink CPU but dropped for Queue
overflow.
