Setting the Ring Speed

3.4 SETTING THE RING SPEED

Before the Token Ring module can be connected to a network, the ring speed must be set. Token Ring signaling takes place at either 4 or 16 Mbps. The default setting is for 4 Mbps. All stations on the same ring must operate at the same speed.

!

CAUTION

A single station configured to the wrong speed may bring down the entire ring, therefore, the ATX should be configured to the appropriate speed before physically connecting it to the network.

Using LCM, at the ATX> prompt, type ringspeed followed by the port number and the desired speed. For example, to set port 9 to 16 Mbps type:

ATX> ringspeed 9 16

The LCM displays 16000000 bits/second.

If set to 4 Mbps, LCM displays 4000000 bits/second.

The Token Ring modules include an LED for each Token Ring port that indicates for which speed the port is configured. If the port is configured for 16 Mbps, the LED will be on; if configured for 4 Mbps, the LED will be off. For Token Ring Switch Modules, set each port’s ring speed, if necessary.

3.5 CONFIGURING THE BRIDGING TYPE

3.5.1Transparent

The ATX defaults to transparent bridging for all ports. If this is acceptable, no further configuration is necessary.
