Maintaining the MX2020 Ethernet Switch
date_range
09-Mar-21
Purpose
For optimum router performance, verify the status of the Gigabit Ethernet ports connected to MPC devices.
Action
On a regular basis:
Check the LEDs on MPC faceplates. The meaning of the LED states differs for various MICs. For more information, see the MX Series Interface Module Reference.
Issue the CLI
