Command Line Interface
perf
The perf branch of the CLI command tree contains commands that
relate to performance services.
The commands in the perf branch can by used by either the
administrator or the operator.
The counters in perf command output are 32-bit values that wrap at
4,294,967,296. To calculate the full value of a counter, multiply
4,294,967,296 by the value in the wrap field, and add the resulting
product to the value in the count field. For example, if a TxFrames
statistic has a count value of 1842953 and a wrap value of 12, the full
value of the counter is:
(4,294,967,296 x 12) + 1842953 = 51,541,450,505.
