Circuit Add Errors
Table F-1 describes error messages and lists choice buttons for typical SNMP set 
failures encountered during attempts to add a circuit. 
Note  – For a standard Circuit Add, the SNMP set command is first sent to the 
lower-numbered node (switch circuit endpoint), not the higher-numbered node as is 
done with a Circuit Delete operation.
For a redirect Circuit Add, the SNMP set commands are sent in the order of 
Primary, Secondary, and Pivot endpoints, not in the order of Pivot, Primary, and 
Secondary, as is done with a Circuit Delete operation.
Table F-1. Errors Encountered During Circuit Add Procedure
Type of Failure SNMP Set Failure Reason Available Choices
Standard PVC – 1st switch 
unreachable (lower-numbered 
node)
Redirect PVC – Primary or 
Secondary switch unreachable
The SNMP request timed out
(1st [or Primary or Secondary] 
endpoint identified).
Abort – Discontinue attempt to add circuit 
(NMS database, switches, and out-of-sync 
status unmodified).
Retry – Attempt to add circuit again.
Standard PVC – 2nd switch 
unreachable (higher-numbered 
node)
Redirect PVC – Pivot switch 
unreachable
The SNMP request timed out
(2nd [or Pivot] endpoint 
identified).
Abort – Discontinue attempt to add circuit 
(NMS database unmodified, circuit 
dangling on 1st [or Primary or Secondary] 
switch; nothing marked out-of-sync). 
PRAM sync of endpoint cards will remove 
traces of circuit from switches.
Ignore – Discontinue attempt to add 
circuit, but add the circuit to the NMS 
database (circuit dangling on 1st [or 
Primary or Secondary] switch; 2nd [or 
Pivot] endpoint card marked out-of-sync). 
PRAM sync of endpoint cards will put 
circuit into switches.
Retry – Attempt to add the circuit again. 
Dangling circuit on 1st (or Primary or 
Secondary) switch will not interfere with 
the retry.
