Maintaining the MX104 MICs and Network Ports
Purpose For optimum performance, verify the condition of the network ports.
Action On a regular basis:
• Check the port LEDs. The meaning of the LED states differs for various uplink ports.
For more information, see “MX104 LEDs Overview” on page 11. If the router detects a
port failure, the router generates an alarm message to be sent to the Routing Engine.
A green status LED indicates that the port is functioning normally.
• From the CLI, issue the show chassis fpc pic-status command.
