The Cisco Nexus 3550-F Fusion (formerly ExaLINK Fusion) collects data traffic statistics
when a FPGA module with
fastmux firmware is installed.
Sent and received packet counters can be viewed using the
show port command.
Please refer to the port page for
Note: This feature is for the
mux firmware only.
The Nexus 3550-F records aggregated statistics on the time it takes for
packets to traverse the device when using switch or mux objects.
The latency statistics can be viewed using the
show latency command:
admin@N3550-F> port B1 show latency Total packets : 5858442 Percentile Latency ---------- ------- maximum 107 ns 99.99 107 ns 99.90 107 ns 99.00 101 ns 95.00 101 ns 90.00 101 ns 75.00 101 ns 50.00 95 ns 25.00 95 ns minimum 95 ns
The latency number is the time it takes from the packet entering the ingress port at the front panel, to the time it leaves the egress port at the front panel.
By default, the
show latency command shows latency statistics for the
To show the latency statistics for a different length of time, the
last argument can be used to specify the number of minutes of
statistics to show.
For example, to show the latency statistics for the last 10 minutes:
admin@N3550-F> port B1 show latency last 10
Because of memory limitations, older latency data is aggregated, so the statistics shown using this command may include more than the requested length of time.
