15600-R1.1.1SWCD= - R1.1.1

Problem Description

If a customer deletes the CISCO15 user id from the 15600 CTC Management interface, database synchronization will be interrupted. Without database synchronization, a 15600 TSC switch can result in traffic loss. A protection switch such as Bidirectional Line Switched Ring (BLSR) or 1+1 is not affected by a database out of sync condition.

This may result in interruptions for that traffic routed through the network element (NE).


In software release 1.1.1, the FTP mechanism used to copy the database file between the active and standby TSC requires the use of a default user, namely CISCO15, to work correctly.

Problem Symptoms

Database synchronization between the active and standby TSC will stop if the default user, CISCO15, is removed from the system.


Downgrade the account to RTRV permission, and change its password from the default.

This bug is resolved in ONS 15600 release R1.1.2.
