Description

Attention LED

Cisco IOS XR Release 7.7.1

The attention LED is available on all ports of the NCS 1004 line cards. This LED can be selectively turned on for a specific QSFP port or simultaneously on all of the QSFP ports using the hw-module location  command. When turned on, the LED flashes yellow. This LED flashing functionality helps field engineers quickly identify a specific port on the line card for troubleshooting, especially in a cluttered environment.

LEDs of 1.2T, 1.2TL, and 2-QDD-C Line Cards

The front view of the 1.2T line card is as below.

Yellow Flashing

Used by the field engineers to identify a specific port in the line card. This is used for troubleshooting purposes.

  • Use the hw-module location location attention-led all-ports command to turn on this LED on all the ports of the line card.

  • Use the hw-module location location attention-led port-number command to turn on this LED on a specific port of the line card.

  • Use the show controllers optics rack/slot/instance/port | in LED command to display the LED status of ports.

ACT LED

Amber (solid)

The line card is booting. This colour appears as soon as the line card is inserted in to the chassis.

Flashing Red

The line card is in the booting phase.

Green

The line card is up and operational (not associated to the traffic status).

QSFP and Trunk port LEDs

Off

The port has not been provisioned.

Red

Major alarm that could lead to a traffic-impacting situation.

Green

Indicates that the module is operational and has no alarm.

Amber (solid)

Indicates a minor alarm (such as low Rx or Tx power), which could lead to a traffic impacting situation.

Amber (flashing)

This is used for troubleshooting, to identify the faulty port of a line card.

Use the controller optics command in the configuration mode to point to a faulty port in the line card.

The port is configured in maintenance mode or the attention LED is enabled for this port.

Note

 

Attention LED is not supported on ACT LED.
