Follow these guidelines when creating and modifying VLANs in your network:
A maximum of 250 VLANs can be active on supported switches, but some
•
models only support 64 VLANs. If VTP reports that there are 254 active
VLANs, 4 of the active VLANs (1002 to 1005) are reserved for Token Ring
and FDDI.
Before you can create a VLAN, the switch must be in VTP server mode or
•
VTP transparent mode. For information on configuring VTP, see the
"Configuring VTP" section on page
• Switches running this IOS release do not support Token Ring or FDDI media.
The switch does not forward FDDI, FDDI-Net, TrCRF, or TrBRF traffic, but
it does propagate the VLAN configuration through VTP.
Table 8-6 through Table 8-10
VLAN media types.
Catalyst 2900 XL and Catalyst 3500 XL switches support Ethernet interfaces
exclusively. Because FDDI and Token Ring VLANs are not locally supported,
you configure FDDI and Token Ring media-specific characteristics only for
VTP global advertisements to other switches.
