Token Ring VLANs
Although the switch does 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 VTP Version 2 advertise information about these Token Ring VLANs:

Configuration Guide.

Token Ring TrBRF VLANs
Token Ring TrCRF VLANs
The switch supports 64 VLANs in VTP client, server, and transparent modes.
Normal-range VLANs are identified with a number between 1 and 1001. VLAN numbers 1002
through 1005 are reserved for Token Ring and FDDI VLANs.
VLAN configuration for VLANs 1 to 1005 are always saved in the VLAN database. If the VTP mode
is transparent, VTP and VLAN configuration are also saved in the switch running configuration file.
The switch also supports VLAN IDs 1006 through 4094 in VTP transparent mode (VTP disabled).
These are extended-range VLANs and configuration options are limited. Extended-range VLANs
are not saved in the VLAN database. See the
page
13-10.
Before you can create a VLAN, the switch must be in VTP server mode or VTP transparent mode.
If the switch is a VTP server, you must define a VTP domain or VTP will not function.
The switch does 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.
