Associated Address (AssocAddress) agent

This mandatory agent is triggered by the output of the Details agent. The SNMP helper configuration for associated devices is a prerequisite for running this agent.

When an interface on a device has been discovered, and basic device information has been retrieved by the Details agent, a stitcher passes the discovered device information to the Associated Address agent. This agent downloads all the other IP addresses associated with the device and adds them to a central registry, held in the translations.ipToBaseName table, provided the device details are not already in the registry. Downloading all the associated IP addresses ensures that any given device is only interrogated once by the main discovery agents, thus reducing the load on the agents. Any attempt to discover a device more than once (using multiple interfaces) is blocked by the Associated Address agent as the device details are already in the translations database.

Provided the device being checked has not already been discovered, a stitcher sends the device details to the appropriate discovery agent for the retrieval of device connectivity and protocol-specific information.
