CANC Commands and Messages

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


Note All commands supported on the Cisco ONS 15454 platform are also supported on Cisco ONS 15454 M2 and Cisco ONS 15454 M6 platforms.


4.1 CANC

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

 
Usage Guidelines

CANC is an autonomous message transmitted by the NE to a user when a session established by that user is terminated because no messages were exchanged for a long period of time (a timeout). There is a default timeout period based on the user’s privilege/security level. Starting with Release 4.0, timeouts can be provisioned through CTC. Starting with Software Release 4.6, timeouts can be provisioned through TL1 with the SET-ATTR-SECUDFLT command. The default timeouts based on privilege/security level are:

  • A Superuser [SUPER] has a timeout period of 15 minutes.
  • A Provisioning [PROV] user has a timeout period of 30 minutes.
  • A Maintenance [MAINT] user has a timeout period of 60 minutes.
  • A Retrieve [RTRV] user has no timeout period.

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, loss of communication), the REPT EVT SESSION message is used.
