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:  36 Downloads:  0
Issue Description
The TDX board reports the Laser_mis_match alarm.
Alarm Information
Laser_mis_match.
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.

:cfg-del-port:1,ip3;

:cfg-add-port:1,ip3,cbwport,0xff;
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:

:cfg-get-phyport:107,all

                             PHY-PORT                                    

                       Bid   Pid   PortType       PortLevel                     

                      

                       107   ip3   ccport         10.7g                         

                       107   ip4   cbwport        0xff                          

  Total records :2                                                                

:cfg-get-port:107,all

                           INSTALLED-PORT                                 

                       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.
Suggestions
If the Laser_mis_match alarm is reported, check configuration consistency between the logical and physical ports.
