    • Optical interface specifications—see the Hardware Compatibility Tool at

  • DWDM Tunable XFP transceivers:


Port LED, one for each port:

  • Off—Port is not enabled.

  • Green—Port is online with no alarms or failures.

  • Yellow—Port is online with alarms for remote failures.

  • Red—The router has detected a failure with alarms for local failures.


Alarms are vendor-specific. Some transceiver vendors might not support every alarm.
