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.
Disable the port; then enable it again.
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
Troubleshooting the TokenSpeed Module
