Overview

Show ethernet statistics in a table format. This applies to SLAX version 1.0 and higher.

 

Description

 

Use this script to quickly get a report table that shows the statistics for all fast Ethernet (fe) interfaces. Displaying the statistics in a table format saves time and makes analysis quick and easy.

This script gathers statistics from each of the fe interfaces and reformats them into a table display, making it easier to read and analyze the information quickly.

 

Set Up


  1. Copy the op-ether-table.slax script to the /var/db/scripts/op directory on the router.
  2. Enable the script by adding the file statement and script filename to the [edit system scripts op] hierarchy level in the configuration. Only superusers can enable scripts in the configuration.

    1	[edit system scripts op]
    2	user@host# set file op-ether-table.slax
  3. Commit the configuration:

    1	[edit]
    2	user@host# commit and-quit

How to Run


  1. To run this script, issue the command op op-ether-table from the CLI operational mode:

    1	user@host> op op-ether-table
  2. The output will appear similar to this:

    01	user@cli> op op-ether-table
