188 Chapter 4: Bridges/Switches and LAN Design
Table 4-18 represents the commands covered in this section and gives a brief description of each
command's function.
Sample Configuration for a Single Switch
When VTP is not in use (in other words, when VTP transparent mode is in use), VLAN
configuration consists of three primary tasks:
1
Enabling VTP transparent mode
2
Creating the VLAN numbers and names
3
Configuring each port's assigned VLAN
First, use the vtp global configuration command to configure VTP transparent mode. Use the
vlan global command to define each VLAN number (required) and associated name (optional).
Then assign each port to its associated VLAN using the vlan-membership interface
subcommand. Example 4-8 shows an example, based on Figure 4-28.
