Chapter 2 Alarm Troubleshooting
Alarm Procedures
Clear the GFP-EX-MISMATCH Alarm
Step 1 Ensure that the vendor equipment is provisioned to send a null extension header in order to interoperate
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/cisco/web/support/index.html for more information or call Cisco TAC
(1-800-553-2447) to report a Service-Affecting (SA) problem.
2.7.89 GFP-LFD
Default Severity: Major (MJ), Service-Affecting (SA)
SDH Logical Objects: CE100T, CEMR, ML100T
The GFP Loss of Frame Delineation alarm applies to Fibre Channel/FICON GFP ports and occurs if
there is a bad SDH connection, if SDH 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.
Note For more information about Ethernet cards, refer to the Cisco ONS 15310-CL and Cisco ONS 15310-MA
Ethernet Card Software Feature and Configuration Guide.
Clear the GFP-LFD Alarm
Step 1 Look for and clear any associated SDH path errors such as LOS or MS-AIS originating at the transmit
node.
Step 2 If the GFP-LFD alarm does not clear, log into the Technical Support Website at
http://www.cisco.com/cisco/web/support/index.html for more information or call Cisco TAC
(1-800-553-2447) to report a Service-Affecting (SA) problem.
2.7.90 GFP-UP-MISMATCH
Default Severity: Major (MJ), Service-Affecting (SA)
SDH Logical Objects: CE100T, CEMR, ML100T
The GFP User Payload Mismatch is raised against Fibre Channel/FICON ports supporting GFP. It occurs
when the received frame user payload identifier (UPI) does not match the transmitted UPI and all frames
are dropped. The alarm is caused by a provisioning error, such as the port media type not matching the
remote port media type. For example, the local port media type could be set to Fibre Channel—1 Gbps
ISL or Fibre Channel—2 Gbps ISL and the remote port media type could be set to FICON—1 Gbps ISL
or FICON—2 Gbps ISL.
