Cause

This issue happens if there is a connection problem between an IX appliance and a WAN-OPT appliance.

Resolution

• Make sure the Network adaptor on a WAN-OPT appliance is connected to a correct network.
• Make sure packets between two appliances aren't dropped by firewall.
• Move two appliances on the same ESXi host and check the connectivity to see if there is any problem inside the ESXi host.
• Review the overall network configurations if this problem only happens when two appliances are on the different ESXi hosts.
