Tunnel status is down between HCX-WAN-IX appliances in a new HCX deployment

Products

• VMware HCX

Issue/Introduction

• From the HCX UI, on the Interconnect > Service Mesh > Appliances page, the Tunnel Status is Down.
• One or more IX appliances at the source and/or destination site is not accessible on the network.

Environment

• VMware HCX 4.11.x
• The HCX service mesh is recently created and has shown the Tunnel Status as Down since inception.

 

Cause

One or more network profiles at the source and/or destination site are misconfigured. 

Example:

• The management network is in the 192.168.10.0/24 network and should be on portgroup VLAN240, which is configured for VLAN 240.
• The management network profile at the source site is configured with an address range in the 192.168.10.0/24 network but is set to use portgroup that VLAN340, which is configured for VLAN 340.
• When the IX appliance is created at the source site, it will have a management interface on the wrong portgroup and will be inaccessible on the network.

Resolution

Reconfigure the network profile(s) such that the IP address ranges and portgroups align.
