Cabletron Systems STS16-20R Media Speed, Max Explorer Rate on Input, Duplex Mode, Operation Mode

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.

Duplex Mode

The port operation mode. Possible values are, as follows:

•

•

•

Auto (A-HDX, A-FDX), the port determines the full-duplex or half-duplex mode automatically.

HDX, half-duplex mode

FDX, full-duplex mode

Operation Mode

The port operation mode. Possible values are as follows:

•Auto

The port is automatically detected, station mode.

•Port

The port will simulate a MAU/LAM and allow NICs to connect directly.

•Station

The port will simulate a NIC and connect to an existing MAU/LAM.

•RI/RO

For SmartStack STS16-20R only, ports 19 and 20. Allows the switch to connect to the RI/RO connector of a MAU or CAU.

➽Note: If you change any configuration parameters of a connected port, the port will close and reopen and you will lose all address information and statistics for that port.
