Dedicated Token Ring Port Adapter

The Dedicated Token Ring port adapter (PA-4R-DTR) is available on Cisco 7500 series routers, Cisco 7200 series routers, and Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI).

The PA-4R-DTR provides up to four IBM Token Ring or IEEE 802.5 Token Ring interfaces. Each Token Ring interface can be set for 4 Mbps or 16 Mbps half-duplex or full-duplex operation and can operate as a standard Token Ring station or as a concentrator port. The default for all interfaces is Token Ring station mode with half-duplex 16-Mbps operation. The PA-4R-DTR connects over Type 1 lobe or Type 3 lobe cables, with each interface providing an RJ-45 receptacle.

Token Ring Interface Configuration Task List

Perform the tasks in the following sections to configure a Token Ring interface:

Specifying a Token Ring Interface (Required)

Enabling Early Token Release (Optional)

Configuring PCbus Token Ring Interface Management (Optional)

Enabling Token Ring Concentrator Port (Optional)

Monitoring and Maintaining the Port (Optional)

Specifying a Token Ring Interface

To specify a Token Ring interface and enter interface configuration mode, use one of the following commands in global configuration mode:

Command

Purpose

 

 

interface tokenring number

Begins interface configuration.

 

 

interface tokenring slot/port

Begins interface configuration for the Cisco 7200 or Cisco 7500 series routers.

 

 

interface tokenring

Begins interface configuration for the Cisco 7500 series routers.

Enabling Early Token Release

Cisco Token Ring interfaces support early token release, a method whereby the interface releases the token back onto the ring immediately after transmitting rather than waiting for the frame to return. This feature can help to increase the total bandwidth of the Token Ring. To configure the interface for early token release, use the following command in interface configuration mode:

Command

Purpose

 

 

early-token-release

Enables early token release.
