Physical Location

This text field can help identify where the station is situated. The information entered here is not displayed anywhere else in the Hub View.

Priority

The priority assigned to a station controls how often it will receive the token and how long it can hold it. In this field, you can assign a station priority number between 0 and 3, with 0 being the lowest and 3 the highest priority. Use caution when assigning a high priority, as this can significantly slow network traffic.

Port Mapping

Port Mapping enables the TRMMIM to determine if station address information can be matched to a specific board and port index. This ability is important during the Automatic Beacon Recovery Process, when the TRMMIM needs to match address information contained in beacon frames with physical port locations so it can determine the “fault region” and locate failing ports. (See the Ring Map chapter for more information about Automatic Beacon Recovery, or ABRP.)

When Port Mapping is enabled, the TRMMIM can determine if a port is physically linked to the MMAC without being mapped as part of the ring network — that is, the device does not participate in neighbor notification. If a port in this condition is detected, the TRMMIM will physically shut down the port to prevent ring problems. Port Mapping is enabled by default.

However, you may want to attach a device to the MMAC — such as a ring analyzer — that does not participate in the normal operation of token ring protocol. In this case, you will want to disable Port Mapping for the port to which that device will be attached, to ensure that the TRMMIM does not shut the port down.

If you wish to insert an analyzer on a ring, be sure you disable Port Mapping on the port you use for insertion; if you don’t, the TRMMIM will detect that a station which is not participating in neighbor notification has been inserted, and will shut down the port. Also, be sure you do not insert anything other than an analyzer into a port whose mapping function has been disabled, since the TRMMIM will not recognize the link status of that port, and will therefore not be able to map ports correctly (since it detects more stations than linked ports).

Click on Enable to enable port mapping for the selected port, or on Disable to disable it.

Reverse MACs

Selecting the Reverse MACs button will toggle the station’s MAC address between Token Ring and Ethernet formats (Token Ring MAC addresses are the reverse bit order of Ethernet MAC addresses). The Upstream and Downstream neighbor addresses will also be affected.
