Catalyst 4500 series switches do not support Token Ring or FDDI media. The switch does not forward
Note
FDDI, FDDI-NET, TrCRF, or TrBRF traffic, but it does propagate the VLAN configuration by using
VTP. The software reserves parameters for these media types, but they are not supported.

Configuring VLANs

Before you configure VLANs, you must use VLAN Trunking Protocol (VTP) to maintain global VLAN
Note
configuration information for your network. For complete information on VTP, see the
Protocol" section on page
VLANs support a number of parameters that are not discussed in detail in this section. For complete
Note
information, refer to the command reference guide.
The VLAN configuration is stored in the vlan.dat file, which is stored in nonvolatile memory. You can

cause inconsistency in the VLAN database if you manually delete the vlan.dat file. If you want to
modify the VLAN configuration or VTP, use the commands described in the following sections and in
the command reference guide.
The following sections describe how to configure VLANs:

Configuring VLANs in Global Configuration Mode
If the switch is in VTP server or transparent mode (see the
page
VLANs in global and config-vlan configuration modes, the VLAN configuration is saved in the vlan.dat
files, not the running-config or startup-config files. To display the VLAN configuration, enter the show
vlan command.
If the switch is in VLAN transparent mode, use the copy running-config startup-config command to
save the VLAN configuration to the startup-config file. After you save the running configuration as the
startup configuration, the show running-config and show startup-config commands display the VLAN
configuration.
