Troubleshooting the TokenSpeed Module

•Port speed and speed sensing are conﬁgured appropriately.

–If the port speed is not set to Auto, and Speed Sense is disabled, the port is forced to operate at a particular speed. Verify that the conﬁgured speed matches the actual speed of the ring.

–If Speed Sense is enabled, be sure that at least one device on the connected ring is not set to Speed Sense.

–If the switch is connected to an intelligent hub that has automatic speed sensing, such as a Bay Networks hub, conﬁgure a speciﬁc speed for the port on the TokenSpeed module and disable the Speed Sense option.

•The ring number assigned to this port does not conﬂict with other ring numbers in the network.

If the ring parameter server tells the port a different ring number from the number that is conﬁgured, the port will deinsert.

4.Disable the port; then enable it again.

5.If the port still fails to insert, try inserting the port into another ring segment.

If the second port inserts successfully, check the status of the ﬁrst ring.

If the second port fails to insert into the other ring, contact Bay Networks customer support. Please be ready to provide the service representative with the information listed on page 4-1.
