Communications Settings for <group_name>

Use the Communications Settings dialog box to configure the communication between the management server and the client.
Management server and client communications settings
Enable communications between clients and the management server
Ensures that the management server and the client computers in this location stay connected, even if the connection for the group is disabled.
Use Group Communication Settings
is unchecked for a location, then this option appears for that specific location.
Management Server List
Specifies the management servers that the clients in the group can connect to.
Servers that you previously added from the management server list in the Policy Components pane appear in this drop-down list. You can apply one management server list at a time.
Downloads the policies from any server in the management server list by using one of the following methods:
  • Download policies and content from the management server
    Group-specific setting only.
  • Push mode
    The client establishes a constant connection to the server. Whenever a change occurs with the server status, it notifies the client immediately.
  • Pull mode
    The client connects to the server periodically, depending on the frequency of the heartbeat setting. The client checks the status of the server when it connects.
    Because of the constant connection, push mode requires a large network bandwidth. Most of the time you can set up clients in pull mode.
Learn applications that run on the client computers
The client collects information about the applications that run on the client and sends the data to the management server.
You can search for and view information about the applications by using the query tool on any one of the policy panes.
To enable this setting, you must also enable site-wide application learning. See:
Heartbeat Interval
Heartbeat interval
The frequency with which the client communicates with and retrieves settings from the server.
At each heartbeat, the server takes the following actions:
  • Updates the logs.
  • Updates the security policy.
  • Checks the communication status between the client and the server.
The default heartbeat interval is 5 minutes.
Let clients upload critical events immediately
(Windows only) When this option is enabled, the client uploads critical events to the management server immediately and does not wait for the heartbeat interval. Critical events include any risk found (except cookies) and any intrusion event. System change events are not considered critical events. This option is enabled by default.
Administrator notifications can alert you right away when the damper period for relevant notifications is set to
Only clients that run version 12.1.4 or later can send critical events immediately. Earlier clients send events at the heartbeat interval only
The download mode (push or pull) does not interact with this setting.
Download Randomization
Enable randomization
Configures whether or not the
Symantec Endpoint Protection Manager
randomizes content downloads from the default management server or a Group Update Provider. Typically, you do not need to change the default settings.
Reconnection Preferences
When you deploy a client installation package, you specify which group the client goes in. You can move the client to a different group. If the client later gets deleted or disconnected and then gets added again and reconnected, the client returns to the original group. Use these settings to keep the client with the group it was last moved to.
  • Use the client’s last-used Group setting
    (Windows and Mac) Use the settings for the group that the client was in before the client disconnected.
  • Use the client’s last-used User mode/Computer mode setting
    (Windows only) If a new user logs on to a client that is configured in user mode, the client stays in the group that the previous user was in. See:
This feature is group-based only, not location-based.
