Chapter 8 Configuring VLANs
VLANs in the VTP Database
VLANs in the VTP Database
You can set the following parameters when you add a new VLAN to or modify an
existing VLAN in the VTP database:
• VLAN ID
• VLAN name
• VLAN type (Ethernet, Fiber Distributed Data Interface [FDDI], FDDI
network entity title [NET], TrBRF or TrCRF, Token Ring, Token Ring-Net)
• VLAN state (active or suspended)
• Maximum transmission unit (MTU) for the VLAN
• Security Association Identifier (SAID)
• Bridge identification number for TrBRF VLANs
• Ring number for FDDI and TrCRF VLANs
• Parent VLAN number for TrCRF VLANs
• STP type for TrCRF VLANs
• VLAN number to use when translating from one VLAN type to another
The “Default VLAN Configuration” section on page 8-28 lists the default values
and possible ranges for each VLAN media type.
Token Ring VLANs
Although the Catalyst 2900 XL and Catalyst 3500 XL switches do not support
Token Ring connections, a remote device such as a Catalyst 5000 series switch
with Token Ring connections could be managed from one of the supported
switches. Switches running this IOS release advertise information about the
following Token Ring VLANs when running VTP version 2:
• Token Ring TrBRF VLANs
• Token Ring TrCRF VLANs
For more information on configuring Token Ring VLANs, refer to the
Catalyst 5000 Series Software Configuration Guide.
