# Configuration file changes

agmon used a single configuration file, ag.cfg, that contained configuration information for each board. Each board was referenced using a board number. oamsys uses a system configuration file that assigns each board:

- A board name, used to refer to the board in software.

- A board number, used to refer to the board in legacy software.

- A board keyword file, containing the configuration information for the board.

The internal structure of the system configuration file and the board keyword file is very different from agmon configuration files. For details on creating a file for your system, refer to Configuring and starting the system with oamsys. For more general information on NMS OAM configuration files, refer to the NMS OAM System User's Manual.
