Displaying Port Statistics


The port statistics information is useful for understanding the data traffic on switch ports. Port statistics information includes the number of incoming and outgoing packets (classified as unicast, multicast, and broadcast), bytes dropped, bytes discarded, Head-End-Replicated (HER) packets, and errors. Use the port-stats-show command to display the port statistics for all active ports on a switch:


CLI (network-admin@switch) > port-stats-show

port-stats-show

Displays port statistics.

time date/time: yyyy-mm-ddThh:mm:ss

Specify a time for the packet count statistics using the timestamp format yyyy-mm-ddThh:mm:ss.


start-time start-time

Specify a start time for the packet count statistics using the timestamp format yyyy-mm-ddThh:mm:ss.

end-time end-time

Specify an end time for the packet count statistics using the timestamp format YYYY-MM-DDTHH:MM:SS

duration duration

Specify the duration in seconds.

interval duration: #d#h#m#s

Specify the interval between statistics collection.

since-start|no-since-start

Specify if the statistics are collected from the start of collecting statistics.

older-than duration: #d#h#m#s

Specify if the statistics are older than the duration in days, hours, minutes, and seconds.

within-last duration: #d#h#m#s

Specify if the statistics are within the duration in days, hours, minutes, and seconds.

port port-list

Specify one or more switch network data port numbers. Multiple ports can be specified as a comma-separated list of numbers or a range (-).
