(Virtual LAN Trunking). 3Com Network Director does not support VLANs based on VLT – only 802.1Q VLANs are supported.

	■ 3Com Network Director does not support VLANs on non-3Com
		switches. VLANs that have been created on non-3Com switches
		cannot be viewed in 3Com Network Director and VLANs cannot be
		created or modified on non-3Com switches from 3Com Network
		Director.

Components	This section covers the main components of the VLAN support in 3Com
	Network Director, namely:
	■	VLAN display:
		■ The Show VLANs toolbar
		■ The Find dialog box
		■ The Options dialog box
		■ The Properties dialog box
		■ The VLAN Configuration report
		■	The Misconfigurations report
		■	The Changes report
	■	VLAN configuration:
		■ The Create VLAN wizard
		■ The Edit Port VLAN Membership wizard

Show VLANs

The Show VLANs functionality in 3Com Network Director allows you to highlight the members of a particular VLAN on the network map. Selecting the Tools > Show VLANs menu option launches the Show VLANs toolbar:
