Status

This field is for informational purposes only, and shows if the port is currently inserted into the ring.

Media Type

This field is for informational purposes only, and shows the media type of the port. Possible values are RJ-45, ST Fiber, and VF-45.

Media Speed

The Token-Ring media speed. Possibilities are 4 or 16 Mbps or Auto. When a switch port configured with Auto discovers a connection to shared media, it will open and insert into the ring. If the open returns with an indication, that the port is the first station to enter the ring, it will close.

This algorithm is analogue to that of auto-sensing adapters, which dictates that an adapter, which is capable of speed adjustment, must have some other station on the ring (typically a server), from which it can sense the network speed.

If you want to have switch ports, which are attached to shared media, it is recommended that you change the default media speed configuration from Auto to either 16 or 4 Mbps.

Max Explorer Rate on Input

The maximum Explorer frame forwarding rate per second. Possible values are Disabled (default) or 0 -5000.

MTU

The Maximum Transfer Unit is the size of the information field of packets to be sent or received. Possible values are 1,500 and 4,472 (default), 8,144, and 17,800. The actual value used depends also on the value configured for the TrBRF (the smaller value is used).

These values correspond to maximum frame size values of 1,548, 4,546 (default), 9,236, and 18,192 respectively.

➽Note: See the description on frame length limit on page 55.

Force AC Bits on SR Frames

This field specifies if AC bits will be set unconditionally when a port forwards certain LLC frames. Possible values are Yes and No (default).

Early Token Release

Whether the port is enabled for Early Token Release (ETR). Possible values are Yes and No. The default is Yes. If Early Token Release is set to Yes and the media speed is 4 Mbps, the switch will force Early Token Release to No.
