SAR Counters
|
Counters that provide information about the Segmentation and Reassembly
(SAR) chip.
|
tx_packets
|
Number of AAL5 packets transmitted.
|
tx_bytes
|
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.
|
tx_total_resource_errs
|
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.
|
tx_total_other_errs
|
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.
|
tx_wred_thresh_drops
|
Total number of WRED maximum threshold drops on this interface. This
counter is included in the tx_total_resource_errs counter.
|
tx_wred_random_drops
|
Total number of WRED random drops on this interface. This counter is
included in the tx_total_resource_errs counter.
|
rx_packets
|
Total number of packets reassembled on this interface by the SAR,
including OAM cells.
|
rx_bytes
|
Number of AAL5 packets received on this interface.
|
rx_total_resource_errs
|
Total number of packet reassemblies that failed due to resource
exhaustion. This error should not occur if the queue thresholds are not
oversubscribed. This error includes rx_buffer_exhaust_errs.
|
rx_total_other_errs
|
Total number of packet reassemblIes that failed due to errors besides
resource exhaustion (not including “no-vc” cells), including
rx_crc32_errors, rx_packet_abort_errs, rx_trailer_len_errs,
rx_mps_errors, and rx_reassembly_timeout.
|
rx_buffer_exhaust_errs
|
Total number of packet reassemblies that failed due to complete buffer
exhaustion on the SAR. This error should not occur if the queue
thresholds are not oversubscribed. This is included in
rx_total_resource_errs.
|
sys_tx_unopen_vc_cls
|
Total number of packets transmitted by this endpoint that failed due to
an error other than those listed in the show controllers atm command
output.
|
Reassembly SAR
|
Counters that provide information specific to the reassembly chip.
|
sys_ecc_and_addr
|
Total number of single bit end and addressing errors detected on the
reassembly SAR.
|
sys_ecc_errors
|
Total number of single bit errors detected on the reassembly SAR.
|
sys_ecc_or_addr
|
Total number of single bit end or addressing errors detected on the
reassembly SAR.
|
Segmentation SAR
|
Counters that provide information specific to the segmentation chip.
|
sys_tx_unopen_vc_cls
|
Total number of packet reassemblies transmitted by this endpoint that
failed due to errors other than those listed in the show controllers atm
command output.
|
sys_rx_unopen_vc_cls
|
Total number of packet reassemblies received by this endpoint that failed
due to errors other than those listed in the show controllers atm command
output.
|
rx_CRC32_errors
|
Total number of packet reassemblies that failed due to an invalid AAL5
CRC32 trailer. This is included in rx_total_other_errs.
|
rx_packet_abort_errs
|
Total number of packet reassemblies that failed due to receiving a
trailer length of 0. This is included in rx_total_other_errs.
|
rx_trailer_len_errs
|
Total number of packet reassemblies that failed due to a packet whose
AAL5 trailer had an invalid trailer length. This is included in
rx_total_other_errs.
|
rx_mps_errors
|
Total number of packet reassemblies that failed due to a packet size
greater than the maximum allowed packet size. This is included in
rx_total_other_errs.
|
rx_reassembly_timeout
|
Total number of packet reassemblies that failed due to timing out before
receiving the last cell of a packet. This is included in
rx_total_other_errs.
|
sys_rx_unopen_vc_cls
|
Packets received on nonexistent VC.
|
RSAR 0
|
RSAR ID.
|
RSAR Build ID
|
Unique number that identifies the RSAR build.
|
SSAR 0
|
SSAR ID.
|
SSAR Build ID
|
Unique number that identifies the SAR build.
