Post-Imaging Tasks

After you image your servers with ESXi and VIBs, you must perform some post-imaging tasks, depending on whether you use an untagged or a tagged management VLAN.

For imaging servers, the VMware Imaging Appliance requires an untagged VLAN. You can continue to use an untagged VLAN for management, or you can use a tagged VLAN.

Untagged Management VLAN

In this scenario, you use the same network for provisioning and management.

• Ensure that the Management Network and VM Network port groups on each host use the untagged VLAN (VLAN ID 0)
• Verify that your DNS and NTP server are routable to the management network and ESXi hosts can reach them. To configure a default gateway or static routes on your ESXi hosts, see https://kb.vmware.com/kb/2001426.

Tagged Management VLAN

In this scenario, you use an untagged VLAN for provisioning and a tagged VLAN for management.

• Modify the Management Network and VM Network port groups on each host to use the tagged VLAN
• Migrate the hosts from the provisioning network to the management network on the TOR switches
• Verify that your DNS and NTP server are routable to the management network and ESXi hosts can reach them. To configure a default gateway or static routes on your ESXi hosts, see https://kb.vmware.com/kb/2001426.
