• No package to receive (status code from McAfee ePO server)

• Agent needs to regenerate GUID (status code from McAfee ePO server)

Other results such as connection refused, failed to connect, connection timeout, or other errors causes

the agent to retry immediately using connection method in the list until the next ASCI nears.

Wake-up calls and tasks

A McAfee Agent wake‑up call triggers an immediate Agent‑Server Communication rather than waiting

for the current Agent‑Server Communication Interval (ASCI) to elapse.

The agent wake‑up client task is supported only on Windows platforms. Use System Tree actions to

wake‑up agents on Unix‑based and Macintosh OS.

There are two ways to issue a wake‑up call:

• Manually from the server — This is the most common approach and requires the agent wake‑up

communication port be open.

• On a schedule set by the administrator — This approach is useful when manual agent‑to‑server

communication is disabled by policy. The administrator can create and deploy a wake‑up task,

which wakes up the agent and initiates Agent‑Server Communication.

Some reasons for issuing an agent wake‑up call are:

• You make a policy change that you want to enforce immediately, without waiting for the scheduled

ASCI to expire.

• You created a new task that you want to run immediately. The Run Task Now creates a task, then

assigns it to specified client systems and sends wake‑up calls.

• A query generated a report indicating that a client is out of compliance, and you want to test its

status as part of a troubleshooting procedure.

If you have converted a particular agent on a Windows system to a SuperAgent, it can issue wake‑up

calls to designated network broadcast segments. SuperAgents distribute the bandwidth impact of the

agent wake‑up call.

Send manual wake-up calls to individual systems

Manually sending an agent or SuperAgent wake‑up call to systems in the System Tree is useful when you

make policy changes and you want agents to call in to send or receive updated information before the

next agent to server communication.

Task

For option definitions, click ? in the interface.

Click Menu | Systems | System Tree, then select the group that contains the target systems.

Select the systems from the list, then click Actions | Agent | Wake Up Agents.

Make sure the systems you selected appear in the Target Systems section.

Next to Wake‑up call type, select whether to send an Agent Wake‑Up Call or SuperAgent Wake‑Up Call as

appropriate.

Accept the default Randomization (0 minutes) or type a different value (0 ‑ 60 minutes). Consider the

number of systems that are receiving the wake‑up call when it is sent immediately, and how much

bandwidth is available. If you type 0, agents respond immediately.
