show performance link

show performance link


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


show performance link link_id=?

show performance link link_id_list=?





link_id=? ID of the link whose performance statistics you need to collect.

To obtain the value, run "show remote_device link".

link_id_list=? ID list of links whose performance statistics you need to collect.
  • To obtain the value, run "show remote_device link".
  • Separate the link IDs with commas (,) or hyphens (-).
  • A maximum of 2048 IDs are allowed.



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.
  • Performance statistics will be updated in real time.
  • Typing "q" on the command line interface (CLI) exits the active performance statistics display.
