4.3.3.10 Maintenance and Management Subsystem
During the running of the routing switch, users must be able to monitor its running status
and that of the whole network in real time. Users also need to configure and manage the
router and the whole network, so an interface must be provided to allow the routing
switch and the user to interact. This interface must provide all the necessary functions
and is easy to operate. An industry-standard command line interface is used. The
command line interface supports user mode, privileged mode and configuration mode,
and enables users to configure the router and manage its faults.
The maintenance management subsystem receives user commands from Telnet,
compiles them and checks their validity, and then creates the execution ID based on the
compilation result, before sending them to the command execution sub-module for
execution. During the execution process, it will invoke services provided by the database
module to save the command configuration.
This maintenance and management subsystem is usually composed of the command
compilation module, command execution module and database.
