Alert Definition Symptom Recommendations
The host has lost redundant
connectivity to a dvPort.
Lost network redundancy to DVPorts
(fault symptom).
Replace the physical adapter or reset
the physical switch. The alert will be
canceled when connectivity is restored
to the DVPort.
The host has lost redundant uplinks to
the network.
Lost network redundancy (fault
symptom).
To determine the actual failure or to
eliminate possible problems, rst
connect to ESX through SSH or the
console:
1 Identify the available uplinks by
running esxcfg-nics -l.
2 Remove the reported vmnic from
the port groups by running
esxcfg-vswitch -U
<affected vmnic#>
aected vSwitch.
3 Link available uplinks to the
aected port groups by running
esxcfg-vswitch -L
<available vmnic#>
aected vSwitch.
Next, check the status of the vmnic in
vSphere Client or the ESX service
console:
1 In vSphere Client, select the ESX
host, click , and then
click Networking.
The vmnics currently assigned to
virtual switches appear in the
diagrams. If a vmnic displays a red
X, that link is currently
unavailable.
2 From the service console, run
esxcfg-nics -l. The output that
appears is similar to the following
example: Name PCI Driver Link
Speed Duplex Description.

Up 1000Mbps Full Broadcom
BCM5780 Gigabit Ethernet. The Link
column shows the status of the link
between the network adapter and the
physical switch. The status can be
either Up or Down. If some network
adapters are up and others are down,
you might need to verify that the
adapters are connected to the intended
physical switch ports. To verify the
connections, shut down each ESX host
port on the physical switch, run the
"esxcfg-nics -l" command, and observe
the aected vmnics. Verify that the
vmnic identied in the alert is still
connected to the switch and
congured properly:
1 Make sure that the network cable
is still connected to the switch and
to the host.
