If the Aand Cbits are not set to B′1′, the port which just inserted into the ring is assumed to be operating at the wrong speed. The Recovery ASIC will prevent that port from entering the ring and will also unwrap all the wrapped ports allowing the existing stations to resume their access to the ring.

When an incorrect speed is detected on the inserting station, the port is wrapped and the status of the port is set to speed mismatch″. The port will only be unwrapped when a transition of phantom is detected on that port or when the user disables and then enables the port.

A threshold for speed detection can be set for each passive module using the following DMM command:

SET MODULE {slot.subslot} SPEED_THRESHOLD {0 to 255}

This threshold is the number of times that the port will be unwrapped as a result of the phantom signal transitions. When the threshold is exceeded, the port will remain wrapped with a status of SPD THRES EXCEEDEDuntil the user disables and re-enables the port. The counter for this threshold is reset every time a port successfully inserts into the ring.

Note that the process of speed detection on the passive modules prevents the existing stations from accessing the ring for the duration of the speed detection process. Therefore, the use of this process is provided as a configuration option on the passive modules. Users can enable or disable the speed detection on each port of a passive module, using the following DMM command:

SET PORT {slot.port} SPEED_DETECT {enable/disable}

Note

The passive modules are shipped from factory with speed detection turned off for all the ports.

The current settings of the SPEED_DETECT function for each port can be displayed using the following command:

SHOW PORT {slot.port} VERBOSE

An example of the output from this command is shown in Figure 91.
