1. Super Agent can be installed on the machine which is reachable to ePO?
Answer: Yes, Super agent is nothing but as normal agent were it enabled option through McAfee Agent policy
2. After updating the settings of Super Agent on Client machine, how other machines will come to know that they should talk to Super Agent instead of ePO?
Answer: For the clients to contact Super agent repository instead of EPO, is possible through McAfee Agent, Create new policy
Repository policy = Edit & select from the list & move SADR to TOP and save.
This new policy can be applied to group or system level or my organization level as it need.
Additionally: Some information with purpose of super agent & attached document
The SuperAgent is an agent with the ability to contact all agents in the same subnet as the SuperAgent, using the SuperAgent wakeup call. Its use is triggered by Global Updating being enabled on the ePolicy Orchestrator (ePO) server, and it provides a bandwidth efficient method of sending agent wakeup calls.
If you operate in a Windows environment and plan to use agent wake-up calls to initiate Agent-server communication, consider converting an agent on each network broadcast segment into a SuperAgent.
SuperAgents distribute the bandwidth load of concurrent wake-up calls. Instead of sending agent wake-up calls from the server to every agent, the server sends the SuperAgent wake-up call to SuperAgents in the selected System Tree segment. When SuperAgents receive this Wake-up call, they send broadcast wake-up calls to all agents in their network broadcast segments.
The process is:
Server sends a wake-up call to all SuperAgents.
SuperAgents broadcast a wake-up call to all agents in the same broadcast segment.
All agents (regular agents and SuperAgents) exchange data with the server.
An agent without an operating SuperAgent on its broadcast segment is not prompted to communicate with the server.
To deploy enough SuperAgents to the appropriate locations, first determine the broadcast segments in your environment and select a system (preferably a server) in each segment to host a SuperAgent. Be aware that agents in broadcast segments without SuperAgents do not receive the broadcast wake-up call, so they do not call in to the server in response to a wake-up call.
