SMG unable to reach gateway defined as part of Static Route.

• Messaging Gateway Hardware

Issue/Introduction

Symantec Messaging Gateway (SMG) cannot communicate with the gateway IP address assigned to a static route. Executing a ping command to the target gateway returns the following error:

Destination host unreachable

Cause

The network interface designated for the static route path lacks physical or virtual network link connectivity (link state is down), preventing packet routing.

Resolution

 

• Verify Network Environment

  • Confirm that switch ports, physical cables, VLAN settings, or hypervisor virtual network adapters (vNICs) are active and functioning correctly.

• Check Interface Link Status

  • Log in to the SMG Command Line Interface (CLI) as admin.

  • Check the link state of the target interface by running: ethtool -s [interface_name] (e.g., ethtool -s eth0)

  • Inspect the command output of the command, ensure that following is seen "Link detected: yes"

  • In case it is not, ensure the ethernet cable is securely plugged into the hardware asset and then reboot the system. When it will become "Link detected: yes" ping the gateway or end MTA.
