Command Reference
Example
The following command will display the 1-second link metrics for the wireless modem card in slot 6,
port 0 of the Cisco uBR7200 series router. It will display the error metrics for the last three entries.

When 1tick-metrics are requested, a table of values for the last n hardware ticks are displayed. Values
are cumulative—every successive row is the sum of the corresponding values in the previous row plus
the values determined for the n-tick period represented by that row. The values displayed are identical
to those of 1second-metrics except that the period is 1 hardware tick.
Post ARQ Codeword Errors Represents the post-ARQ errored codewords detected in the last 1
second. This is the number of codewords not passed to the PCI
physical layer by the ARQ because they remained uncorrected even
after ARQ.
Post ARQ Good Codewords Represents the sum of the total number of codewords received by this
radio link in the last 1 second.
Consecutive Codeword
Errors
Represents the site of the largest grouping of pre-ARQ codeword
errors received over the last 1 second.
Repeat Request Count Represents the number of unique repeat requests that enter a “pending
repeat request” list.
Repeat Request Event Count Represents the number of Retransmit Requests (RR) that were serviced
during the last second. A serviced RR is one that is drawn from the
“pending RR list” and requested by the remote end.
Transmit ARQ Count Represents the number of unique ARQs that were received by the
transmit side of the local end during the last second. This provides an
indication of how error-free the transmissions of the local end are
being received by the remote end.
Transmit ARQ Event Count Represents the number of ARQs that were drawn from the pending
ARQs list and serviced during the last second. A serviced ARQ results
in a retransmitted codeword.
Corrected Sync Byte Errors Represents the number of sync byte errors that were seen by the Viterbi
decoder in the codec but were corrected by the Reed-Solomon decoder
over the last 1 second.
