Usage Guidelines

This command runs the integrated Python script watch.py to run the specified show command periodically and display the output accordingly. In the script, CLI paging is disabled so that user input is not needed, and CLI refreshing is disabled so that the keyword no-refresh is not needed in auto-refreshing commands.

Example

The following example runs the show ports command for port 11 runs 15 times with an interval of 30 seconds:

# watch "show ports 11 statistics port-number no-refresh" count 15 interval 30
