If you have a network with multiple VLANS then it is important to have a descriptive name given to these VLans to identify and for ease of management.
In Cisco IOS this can be done from the vlan database configuration mode
Core_Switch# vlan database
Core_Switch(vlan)# vlan 2 name LEGAL
Now, the following command should show the descriptive name assigned earlier:
Core_Switch# show vlan brief
