## Summary

Lost uplink redundancy on DVPorts. Physical NIC is down.

## Causes

Failure of the network cable, disconnect of cable, failure of the physical network card, failure of network switch, port, and so on.

## Resolutions

Check the physical connection of the vmnic specified in the alert, and the configuration of the attached network switch.

Note that by browsing the Veeam view **\_vCenter Storage Network Topology** you can see which virtual switch is impacted, and which VMs are attached to the impacted switch.

Refer to this [VMware KB article](http://kb.vmware.com/kb/1009515) for more information on troubleshooting network connectivity issues.
