Alarm Procedures
The Automatic Path Protection Switch Caused by Payload Defect Indication (PDI) condition indicates
that automatic UPSR switching occurred because of a “PDI-P” alarm on page 2-121. If the UPSR is
configured for revertive switching, it reverts to the working path after the fault clears.
Note This condition is only reported if the path protection is set up for revertive switching.
Clear the AUTOSW-PDI Condition
Step 1 Complete the “Clear the PDI-P Condition” procedure on page 2-122.
Step 2 If the condition 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).

path when the SD-P is resolved.
