vSphere Network Health Check Video

vSphere Network Health Check – New feature in vSphere 5.1

In this video you’ll see a new feature introduced in the vDS 5.1, the Network Health Check (NHC).

As I already wrote in my article about New features and enhancements in Networking in vSphere 5.1, the network health check can detect misconfiguration in the vDS. The NHC can check whether the problem resides in one of those parameters:  VLAN, MTU or Teaming and Failover.

The vSphere Network Health Check can detect a miss-configuration at the VLAN level, MTU level or at the Teaming level.

In this video from VMware TV, you’ll be able to see how this feature works.

vSphere Distributed Switch“This unique tool helps detect misconfigurations across the Physical switch and VDS parameters. You don’t have to now spend countless hours in troubleshooting network issues caused due to misconfiguration.”

The lab config:

There are 2 hosts connected each to the distributed switch. The vDS has multiple distributed dport groups, which are configured with different VLANs.

There are multiple uplinks, which are mapped to VMnics. The VMnics are connected to the external physical switch ports, which are configured with VLAN trunks , MTU and Teaming. Those parameters must match those configured on the distributed port group.

That’s where the VMware vSphere Network Health Check can verify the MTU, VLAN or Teaming and Failover.

You’ll be able to see that when a VLAN ID is modified (to 1800) on VM network port group, and after checking the status, there is a warning.

On the image below you can see that when the host gets selected, the VLAN 1800 isn’t supported on the physical switch.
