coIfXcvrLaserOperStatus

Module: CISCO-OPTICAL-IF-EXTN-MIB

OID (symbolic): CISCO-OPTICAL-IF-EXTN-MIB::coIfXcvrLaserOperStatus

OID (numeric): 1.3.6.1.4.1.9.10.66.1.4.1.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: This object indicates the current operational status of the laser on this interface.

'transmitting': The laser is on.

'degraded': The laser is on, but there is a fault that causes it to transmit in a degraded manner.

'down': The laser is shut down, either because of error conditions or because it has been administratively disabled. This state indicates that the laser is shut down due to conditions other than Laser Safety Control or Forward Laser Control.

'lscDown': The laser is shut down due to Laser Safety Control (LSC) mechanisms such as Automatic Laser Shutdown (ALS), i.e., due to a fault in the receive direction at this interface.

'flcDown': The laser is shut down due to Forward Laser Control, i.e., due to a fault on the cross-connected interface.

'unknown': The operational status of the laser cannot be determined.

If the value of coIfXcvrLaserAdminStatus is 'down', then this object also indicates 'down'. If coIfXcvrLaserAdminStatus is set to 'up', then the value of this object should change to 'transmitting' if the laser is functioning properly.

What is coIfXcvrLaserOperStatus?

Reports the current operational state of the interface's laser, such as transmitting normally, transmitting in a degraded mode due to a fault, or shut down.
