In Cisco UCS Central you can publish,
or push, global VLANs, and VSANs down to the Cisco UCSdomains. You no longer have to configure and associate
a global service profile to deliver a globally defined VLAN or VSAN.
Cisco UCS Central makes all
applicable global VLANs and VSANs available for publishing to the registered Cisco UCSdomain.
This assumes that the global VLANs
or VSANs are available to the domain group. You can automate the publishing of the
global VLAN or VSAN with either direct API integration or the use of Cisco UCS Central CLI. This
functionality is not available through the UI.
When you delete VLANs, make sure that the VLAN does not reference any
vNIC template or LAN connectivity policy. Also make sure that no service
profile uses that global VLAN. If you choose to delete a global VLAN, make sure
that you delete its organization permissions first, prior to deleting the

VSANs Persisting Locally
Once you push global
VLANs and VSANs down to a UCS domain, they persist there, even if you

This is by design. If you are not going to use the global VLAN or VSAN again,
and you wish to delete the deployed VLAN or VSAN in the UCS domain, use the
Local function for the specific VLAN or VSAN. Once it is localized,
then you can delete the VLAN or VSAN.

FCoE VLAN ID
When you create new
global VSANs from the SAN cloud, the default FCoE VLAN ID value is 1. This is
in conflict with the global default VLAN ID value.

You can deploy global VLANs and VSANs to a UCS

available with the CLI. It can benefit those customers using local service profiles, who
want to utilize and access global objects from Cisco UCS Central.
