Clear The Gfp-Ex-Mismatch Alarm; Gfp-Lfd; Clear The Gfp-Lfd Alarm; Gfp-Up-Mismatch - Cisco ONS 15310-CL Troubleshooting Manual

Chapter 1 Alarm Troubleshooting
The GFP Extension Header Mismatch alarm is raised on Fibre Channel/fiber connectivity (FICON) GFP
ports when it receives frames with an extension header that is not null. The alarm occurs when a
provisioning error causes all GFP frames to be dropped for 2.5 seconds. To clear this alarm, ensure that
both end ports are sending a null extension header for a GFP frame.

Clear the GFP-EX-MISMATCH Alarm

Ensure that the vendor equipment is provisioned to send a null extension header in order to interoperate
Step 1
with the Fibre Channel/FICON GFP ports.
Step 2 If the GFP-EX-MISMATCH alarm does not clear, log into the Technical Support Website at
http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447) to report a
Service-Affecting (SA) problem.

1.7.101 GFP-LFD

The GFP Loss of Frame Delineation alarm applies to Fibre Channel/FICON GFP ports and occurs if
there is a bad SONET connection, if SONET path errors cause GFP header errors in the check sum
calculated over payload length (PLI/cHEC) combination, or if the GFP source port sends an invalid
PLI/cHEC combination. The loss is service affecting.

Clear the GFP-LFD Alarm

Look for and clear any associated SONET path errors such as LOS or AIS-L originating at the transmit
Step 1
node.
If the GFP-LFD alarm does not clear, log into the Technical Support Website at
Step 2
