VLAN Configuration
Configuring VLANs in a network of Cisco switches requires just a few simple steps:
Step 1 Create the VLAN itself.
Step 2 Associate the correct ports with that VLAN.
The challenge relates to how some background tasks differ depending on how the Cisco VLAN
Trunking Protocol (VTP) is configured, and whether normal-range or extended-range VLANs are
being used.
