request chassis port-led

Syntax

Description

Enable remote port identification of the Modular Interface Card (MIC) or PIC by making the LED of the appropriate active port blink for a duration of time. You can also make the LEDs of all active ports, specific active ports, and specific port types blink. For instance, on MX480 routers with MPC7E-MRATE, you can make the LED of all active ports that support port speeds of 100 Gbps blink. Enabling remote port identification provides cabling assistance and reduces cabling mistakes.

Note:

You can stop a LED from blinking before the end of duration. After the LED stops blinking, it resumes its normal operation of indicating current link status of the port.

Options

start

Start blinking of the LEDs of the specified ports.

stop

Stop the LEDs of the specified ports from blinking.

fpc-slot fpc-slot-number

(MX Series routers) Modular Port Concentrator (MPC) slot number. Replace fpc-slot-number with a value appropriate for your router:

  • MX240 routers—0 through 2.

  • MX480 routers—0 through 5.

  • MX960 routers—0 through 11.

  • MX2010 routers—0 through 9.

  • MX2020 routers—0 through 19.

  • MX10003 routers—0 through 1.

  • MX10008 routers—0 through 6.

pic-slot pic-slot-number

(MX Series routers) MIC slot number. Replace pic-slot-number with a value from 0 through 3. For MX10008 routers with JNP10K-LC2101 MPC only, replace pic-slot-number with a value from 0 through 5.

port port-number

Port number. Replace port-number with a value appropriate for your MPC or line card:

  • MIC-MRATE—0 through 11.

  • MX10003 MPC—0 through 5 for PIC 0 and 0 through 11 for PIC1

  • JNP10K-LC2101 MPC—0 through 3 per PIC. JNP110K-LC2101 supports 6 built-in PICs and each PIC supports 4 ports.

all-10g

Active ports that support port speed of 10 Gbps.

all-40g

Active ports that support port speed of 40 Gbps.

all-100g

Active ports that support port speed of 100 Gbps.

all-ports

All active ports.

duration duration

Duration, in seconds, to perform LED blinking. Replace duration with a value from 0 through 65,535. The default duration is 5 minutes (300 seconds).
