Maintaining MX2020 Adapter Cards

 

Purpose

Action

On a regular basis:

  • Issue the CLI show chassis adc command to check the status of installed ADCs. As shown in the sample output, the value Online in the column labeled State indicates that the ADC is functioning normally:

user@host> show chassis adc
