show performance port

show performance port


The show performance port command is used to query the performance statistics on ports. If you want to analyze the real-time performance statistics on ports, run this command.


show performance port port_id=?

show performance port port_id_list=?





port_id=? ID of the port whose performance statistics you need to collect.

To obtain the value, run "show port general".

port_id_list=? ID list of ports whose performance statistics you need to collect.
  • To obtain the value, run "show port general".
  • Separate the port IDs with commas (,).



Usage Guidelines

  • After this command is executed, performance data categories are displayed. You can enter the serial number before a category and press "Enter" to view the category of data. You can enter multiple serial numbers and use commas (,) to separate them.
  • By default, performance statistics will be refreshed every three seconds. To refresh performance statistics instantly, press "Enter".
  • Typing "q" on the command line interface (CLI) exits the active performance statistics display.


Query the read I/Os of port P1 on interface module "1". The module resides on controller 1 of engine "0". The command output varies depending on a specific product.
