Chapter 3 Initial Configuration of the ML-Series Card
Cisco IOS Command Modes
Note If there is a parsing error when the Cisco IOS startup configurat ion file is downloaded and
parsed at initialization, an ERROR-CONFIG alarm is reported and appears under the CTC
alarms tab or in TL1. No other Cisco IOS error messages regarding the parsing of text are
reported to the CTC or in TL1. An experienced Cisco IOS user can locate and troubleshoot the
line in the startup configuration file that produced the parsing error by opening the Cisco IOS
CLI and entering a copy start run command.
Note A standard ONS 15310 database restore reinstalls the Cisco IOS startup config file, but does not
implement the Cisco IOS startup config on the ML-Series. Complete Step 6 to load the
Cisco IOS startup config file from the 15310-CL-CTX to the ML-Series card.

Database Restore of the Startup Configuration File

The ONS 15310-CL includes a database restoration feature. Restoring the database will reconfigure a
node and the installed line cards to the saved provisioning, except for the ML-Series card. The
ML-Series card does not automatically restore the startup configuration file saved in the database.
A user can load the saved startup configuration file onto the ML-Series card in two ways. He can revert
completely to the saved startup configuration and lose any additional provisioning in the unsaved
running configuration, which is a restoration scheme similar to ot her ONS cards, or he can install the
saved startup configuration file on top of the current running configuration, which i s a merging
restoration scheme used by many Cisco Catalyst devices.
To revert completely to the startup configuration file saved in the restored database, the user needs to
soft reset the ML-Series card. Right-click the ML-Series card in CTC and choose Soft-reset or use the
Cisco IOS CLI reload command to reset the ML-Series card.
To merge the saved startup configuration file with the running configuration, use the Cisco IOS CLI copy
startup-config running-config command. This restoration scheme should only be used by experienced
users with an understanding of the current running configuration and the Cisco IOS copy command. The
copy startup-config running-config command will not reset the ML-Series card. The user also needs
to use the Cisco IOS CLI copy running-config startup-config command to save the new merged
running configuration to the startup configuration file.
Cisco IOS Command Modes
The Cisco IOS user interface has several different modes. The commands available to you dep end on
which mode you are in. To get a list of the commands available in a given mode, type a question mark
(?) at the system prompt.
Table 3-2 describes the most commonly used modes, how to enter the modes, and the resulting system
prompts. The system prompt helps you identify which mode you are in and, therefore, which commands
are available to you.
