CANC Commands and Messages

This chapter provides cancel (CANC) commands and autonomous messages for the Cisco ONS 15454 SDH, Cisco ONS 15454 M2, and Cisco ONS 15454 M6.


NoteAll commands supported on the Cisco ONS 15454 SDH platform are also supported on Cisco ONS 15454 M2 and Cisco ONS 15454 M6 platforms.


4.1 CANC

(Cisco ONS 15454 SDH) The Cancel (CANC) message reports the occurrence of a session timeout event.

 
Usage Guidelines

CANC is an autonomous message transmitted by the network element (NE) to a user when a session established by that user is terminated because no messages were exchanged for a long period of time and the session times out. There is a default timeout period based on the user’s privilege/security level. Timeouts can be provisioned through Cisco Transport Controller (CTC). Timeouts can be provisioned with the SET-ATTR-SECUDFLT command. The default timeouts based on privilege/security level are:

  • The Superuser (SUPER) has a timeout period of 15 minutes.
  • The Provisioning user (PROV) has a timeout period of 30 minutes.
  • The Maintenance (MAINT) user has the timeout period of 60 minutes.
  • The Retrieve user (RTRV) has no timeout.

When a timeout occurs, the corresponding port drops the session and the next session initiation at that port requires the regular login procedure.

The CANC message is only used to indicate that a session has been terminated because of a timeout. If a session is terminated for a different reason (for example, forced logout or loss of communication), the REPT EVT SESSION message is used.
