Nortel Networks NTRN10AN Application of TL1 commands from a TL1 script file, Security levels

2-130Operation, administration, and maintenance (OAM) features

The existence of any blocking conditions on the shelf processor and/or the network processor can block the Save and Restore application from executing any further actions. Users are able to check for the existence of Save and Restore blocking conditions.

A Save and Restore activity can be terminated at any point before the action is complete. Users can also recommence the Save and Restore application after the application has been arrested.

Application of TL1 commands from a TL1 script file

A TL1 script file is a collection of TL1 commands which by their nature impact the configuration of a network element. These TL1 commands are captured by logging the Data Base Changes commands for all individual network elements and storing them on a remote database. During a TL1 Script Load, a script file is created from the logged database TL1 commands, downloaded from the remote location, and temporarily stored on the network processor’s file system. Once the file is successfully stored, each TL1 command contained in the script file is issued on the target network element following a ‘commit’.

The user is able to apply TL1 scripts to a single network element after the Restore process by issuing a TL1 Script-specific set of commands to Load and Commit TL1SCRPT to that specific network element. This process is similar to the Restore and Commit Provisioning data applications. TL1 commands issued to the targeted network element from the TL1 script that did not complete successfully are logged onto that targeted network element.

Security levels

OPTera Metro 3500 network elements and network processors support multiple security access levels. This feature reduces accidental or intrusive interruption of service.

There are five UPC security levels that allow a range of task execution capabilities:

Level 5

•Surveillance allows surveillance of all network elements in the network processor span of control. A user account with a level 5 UPC can only be used to log into a network processor using a local connection. A user account with a level 5 UPC is valid only under the following circumstances:

—a login to the network processor from Preside or a managed object agent (MOA)

—a login to the network processor, if the network processor is the gateway to the network
