Security and Timing
This chapter provides information about Cisco ONS 15454 SDH users and SDH timing. To provision
security and timing, refer to the Cisco ONS 15454 SDH Procedure Guide.
Chapter topics include:
• 9.1 Users and Security, page 9-1
• 9.2 Node Timing, page 9-7
9.1 Users and Security
The CISCO15 user ID is provided with the ONS 15454 SDH system, but this user ID is not prompted
when you sign into Cisco Transport Controller (CTC). This ID can be used to set up other
ONS 15454 SDH users. (To do this, complete the “Create Users and Assign Security” procedure in the
Cisco ONS 15454 SDH Procedure Guide.)
You can have up to 500 user IDs on one ONS 15454 SDH. Each CTC or Transaction Language One
(TL1) user can be assigned one of the following security levels:
• Retrieve—Users can retrieve and view CTC information but cannot set or modify parameters.
• Maintenance—Users can access only the ONS 15454 SDH maintenance options.
• Provisioning—Users can access provisioning and maintenance options.
• Superusers—Users can perform all of the functions of the other security levels as well as set names,
passwords, and security levels for other users.
By default, multiple concurrent user ID sessions are permitted on the node, that is, multiple users can
log into a node using the same user ID. However, you can provision the node to allow only a single login
per user and prevent concurrent logins for all users.
Note You must add the same user name and password to each node the user accesses.
9.1.1 Security Requirements
Table 9-1 shows the actions that each user privilege level can perform in node view.
