This document shows you how to create VLANs in the Cisco Unified Computing System (UCS).

In the Cisco UCS, a named VLAN creates a connection to a specific external LAN. The VLAN isolates traffic
to that external LAN, which includes any broadcast traffic.

The name that you assign to a VLAN ID adds a layer of abstraction that allows you to globally update all
servers associated with service profiles that use the named VLAN. You do not need to reconfigure the servers
individually to maintain communication with the external LAN.

You can create more than one named VLAN with the same VLAN ID. For example, if servers that host
business services for HR and Finance need to access the same external LAN, you can create VLANs named
HR and Finance with the same VLAN ID. Then, if the network is reconfigured and Finance is assigned to a
different LAN, you only have to change the VLAN ID for the named VLAN for Finance.

Cisco recommends that you have a working knowledge of these:
