Master Agent and Sub Agent

The M770 ATM Switch is a fully distributed ATM switch. Each module has its own switching and CPU power. In order to present the switch as a single and united entity, one module is automatically elected as a Master Agent while the other modules are Sub Agents. The Master Agent status is shown by the Network Management Agent (NMA) LED.

The Master Agent is the module hosting the Management LEC with all its functionality: IP address and switch-wide information. The Master Agent is also a regular module with all the functionality of a Sub-Agent such as controlling the physical ports, virtual ports and download.

The Master and Sub Agents have slightly different CLI options. For example, the Master Agent has the “ip” command and the “access” command which will enable you to access a Sub Agent from the Master Agent. A simple way to find out whether you are currently communicating with a Master Agent is to type help at the command line and check whether there is an “access” command option.

All the information configured to the Master Agent (IP, ATM Prefix) is backed up by all the Sub Agents, so if the Master Agent is removed, another module will be elected and all previous configuration settings will be kept.
