Data rate (Token-Ring)

Some Token-Ring drivers are able to automatically detect the data transmission rate on the ring and configure the adapter accordingly. However, if the adapter is the first active station on the ring, auto-detection will not work and the data rate must be set manually, usually to 4Mbps or 16Mbps. We recommend that you configure servers for a specific ring speed.

NOTE: Although it is desirable to set the ring to the highest rate possible, all adapters on the ring should operate at the same rate. Some older Token-Ring adapters can only be set to 4Mbps.
