Viewing port utilization on Brocade switches

The Brocade Silkworm family of switches maintain a number of important performance and reliability counters for each switch port. Performance and reliability counters for specific switch ports can be viewed with the porterrshow, portshow and portStatsShow commands. To view system wide throughput statistics, the portPerfShow command can be run with an optional interval:

switch1:admin> portPerfShow 5

The individual switch ports are listed above the dashes, and the numbers below the dashes contain the number of bytes transmitted and received per second. This is a super useful tool for getting a high level overview of what your switch is doing.

  1. Sorry , Matty
    I know the command “portperfshow” can be run with an optional interval for real-time monitor.
    but it seems only can print on screen.
    I want to know is there any way to save the statistics data as a text file ?
    thanks again.

  2. Another, more simple, option is use PuTTY (allow ssh and telnet protocol) for the connection to the switch.
    Whith PuTTY you can save the full session output to a file.

    Anyway I agree that “expect” is a more professional option.
