4 Apply the configuration of the distributed port group and VMkernel adapter from vCenter Server to
the host.
n
Push the correct configuration of the distributed port group and VMkernel adapter from
vCenter Server to the host.
a In the vSphere Web Client, navigate to the host.
b Under the Manage tab, click Networking
c From the Virtual switches list, select the distributed switch and click Rectify.
n
Wait until vCenter Server applies the settings within the next 24 hours.
Hosts on vSphere Distributed Switch 5.0 and Earlier Lose
Connectivity to vCenter Server
Hosts on a vSphere Distributed Switch 5.0 and earlier cannot connect to vCenter Server after a port group
configuration.
Problem
After you change the networking configuration of a port group on a vSphere Distributed Switch 5.0 or
earlier that contains the VMkernel adapters for the management network, the hosts on the switch lose
connectivity to vCenter Server. In the vSphere Web Client the status of the hosts is nonresponsive.
Cause
On a vSphere Distributed Switch 5.0 and earlier in vCenter Server, the port group containing the VMkernel
adapters for the management network is misconfigured in vCenter Server and the invalid configuration is
propagated to the hosts on the switch.
Solution
1 Connect to an affected host by using the vSphere Client.
2 Under Configuration, select Networking.
3 In the vSphere Standard Switch view, create a new standard switch if the host does not have a standard
switch suitable for the management network.
a Click Add Networking.
b In the Add Network wizard, under Connection Types select Virtual Machine, and click Next.
c Select Create a vSphere standard switch.
d Under the Create a vSphere standard switch section, select one or more unoccupied physical
adapters on the host to carry the management traffic and click Next.
If all physical adapters are already busy with traffic from other switches, create the switch without
a physical network adapter connected. Later, remove the physical adapter for the management
network from the proxy switch of the distributed switch and add it to this standard switch.
e In the Port Group Properties section, type a network label that identifies the port group that you
are creating and optionally a VLAN ID.
f Click Finish.
