Understanding Token Ring VLANs

The following section describes the two Token Ring VLAN types supported on network devices running
VTP version 2:
•
•
Catalyst 6500 series switches do not support Inter-Switch Link (ISL)-encapsulated Token Ring frames.
Note
When a Catalyst 6500 series switch is configured as a VTP server, you can configure Token Ring
VLANs from the switch.
Token Ring TrBRF VLANs
Token Ring Bridge Relay Function (TrBRF) VLANs interconnect multiple Token Ring Concentrator
Relay Function (TrCRF) VLANs in a switched Token Ring network (see
be extended across a network devices interconnected via trunk links. The connection between the TrCRF
and the TrBRF is referred to as a logical port.
OL-11439-03
Ethernet VLAN 1 uses only default values.
Except for the VLAN name, Ethernet VLANs 1006 through 4094 use only default values.
You can configure the VLAN name for Ethernet VLANs 1006 through 4094.
VLAN name
VLAN type (Ethernet, FDDI, FDDI network entity title [NET], TrBRF, or TrCRF)
VLAN state (active or suspended)
Security Association Identifier (SAID)
Bridge identification number for TrBRF VLANs
Ring number for FDDI and TrCRF VLANs
Parent VLAN number for TrCRF VLANs
Spanning Tree Protocol (STP) type for TrCRF VLANs
