show performance port

show performance port


The show performance port command is used to query the performance statistics on a port. Run this command to analyze the performance statistics on a port in real time.


show performance port port_id=?

show performance port port_id_list=?






ID of a port on which you want to query performance statistics.

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


ID list of ports on which you want to query performance statistics.

  • To obtain the value, run "show port general".
  • Separate the port IDs with commas (,).
  • A maximum of 50 IDs can be queried.



Usage Guidelines

  • You will be prompted with optional performance statistics categories upon running this command. In this condition, typing a number or multiple numbers (separated by commas) for the selected categories and pressing "Enter" display the performance statistics for those categories.
  • 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 performance statistics on the read I/Os flowing through port P1 on interface module "1", where the module resides on controller 1 of engine "0". The command output varies depending on a specific product.
