Configuring Heartbeat using Email Security CLI Configuring a heartbeat with GMS is exclusively available on the Email Security Command Line Interface (CLI). To configure a Heartbeat with GMS using the Email Security CLI, complete the following steps: 1 Login to the SNWLCLI as admin. 2 Enter the command gms. This displays the EMS current settings for the GMS heartbeat displayed. 3 Next, set the EMS appliance heartbeat. In this example, the heartbeat interval is 60 seconds. 4 Enter the destination IP address of your GMS server. In this example, the destination IP address is 10.195.11.38. NOTE: It is mandatory to send heartbeat messages to a GMS management server to reliably report the Unit Status (UP or DOWN) for an Email Security appliance in GMS.
