!--- Set the VLAN Trunk Protocol (VTP) mode. !--- In this example, the mode is set to transparent. !--- Dependent upon your network, set the VTP mode accordingly. !--- Refer to Understanding and Configuring VLAN Trunk Protocol (VTP) !--- for more information on VTP.

Catalyst6500> (enable) set vtp mode transparent
VTP domain modified


!--- Add VLAN 2. VLAN 1 already exists by default.
 
Catalyst6500> (enable) set vlan 2
VLAN 2 configuration successful


!--- Add port 4/2 to VLAN 2.

Catalyst6500> (enable) set vlan 2 4/2
VLAN 2 modified.
VLAN 1 modified.

!--- Enable trunking on port 4/1.

Catalyst6500> (enable) set trunk 4/1 1,2 dot1q on
Vlan(s) 1,2 already allowed on the trunk
Please use the 'clear trunk' command to remove vlans from allowed list.
Port(s)  4/1 trunk mode set to on.
Port(s)  4/1 trunk type set to dot1q.
Catalyst6500> (enable) 


!--- Enable spanning tree portfast on the ports. Refer to !--- Using Portfast and Other Commands to Fix Workstation Startup Connectivity Delays !--- for more information on how to enable portfast.

Catalyst6500> (enable) set spantree portfast 4/1 enable

Warning: Connecting Layer 2 devices to a fast start port can cause
temporary spanning tree loops. Use with caution.

Spantree port  4/1 fast start enabled.
Catalyst6500> (enable) set spantree portfast 4/2 enable

Warning: Connecting Layer 2 devices to a fast start port can cause
temporary spanning tree loops. Use with caution.

Spantree port  4/2 fast start enabled.

!--- If you want to ONLY allow VLAN 1 and VLAN 2 on trunk port 4/1, do this. !--- A trunk port allows all VLANs by default.
