Laser_mis_match Alarm Is Generated Due to Configuration Inconsistency Between the Logical and Physical Ports of the TDX Board

Publication Date:  2012-07-25 Views:  91 Downloads:  0
Issue Description
The TDX board reports the Laser_mis_match alarm.
Alarm Information
Handling Process

Delete the original ip3 logical port and add a new logical port. Set the parameters of the new logical port to the same as those of the corresponding physical port. Then, the Laser_mis_match alarm is cleared.


Root Cause

Suspect that this alarm is caused by configuration inconsistency between the logical and physical ports of the TDX board. The following ports are applicable to NG WDM equipment:

cbwport: client-side black-and-white optical port, with 6 as its ID.

ccport: client-side colored optical port, with 7 as its ID.

lcport: line-side colored optical port, with 8 as its ID.

cfeport: electrical port, with 9 as its ID.

Run the following commands to query logical and physical ports:



                       Bid   Pid   PortType       PortLevel                     


                       107   ip3   ccport         10.7g                         

                       107   ip4   cbwport        0xff                          

  Total records :2                                                                



                       Bid   Pid   PortType     PortLevel                     


                       107   ip3   cbwport        0xff


                       107   ip4   cbwport        0xff                          

  Total records :2                                                                

The query result indicates that configurations of logical and physical ports ip3 are different.
If the Laser_mis_match alarm is reported, check configuration consistency between the logical and physical ports.
