To test connectivity between the on-premises Endpoint Security (HX) appliances and cloud Endpoint Security (HX) servers using the CLI:
Log in to the on-premises Endpoint Security (HX) appliance using the SSH protocol and the IP address or hostname of the appliance's management interface.
Enable CLI configuration mode.
hostname > enable
hostname # configure terminal
Telnet to the cloud Endpoint Security (HX) server on port 80:
hostname # telnet <hostname-or-IPaddress> 80
where <hostname-or-IPaddress> is the host name or public IP address of the cloud Endpoint Security (HX) appliance.
In the output from this command, verify that telnet succeeds in making a connection.
Trying <IPaddress-or-host-name>...
Connected to <IPaddress-or-host-name>.
Escape character is '^]'.
Repeat these steps with the on-premises HXD (DMZ) appliance, if there is one.
