Circuit Modify Errors
Table F-2 describes error messages and lists choice buttons for typical SNMP set
failures encountered during attempts to modify an existing circuit.
Note – For a standard Circuit Modify, 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 Modify, 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-2. Errors Encountered During Circuit Modify 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 modify
circuit (NMS database, switches, and
out-of-sync status unmodified).
Retry – Attempt to modify 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 modify
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
circuit modification.
Ignore – Discontinue attempt to modify
circuit, but modify the circuit in the NMS
database (circuit modify on 1st [or Primary
or Secondary] switch; 2nd [or Pivot]
endpoint card marked out-of-sync). PRAM
sync of endpoint cards will modify circuit
on both switches.
Retry – Attempt to modify the circuit again.
Dangling circuit modification on 1st [or
Primary or Secondary) switch will not
interfere with the retry.
