If a “Reply from…” or “...is alive...” message appears, the devices can
communicate.
If a “Request timed out” message appears (or the command times out), the
devices cannot communicate. Trace the cabling. If needed, reconnect the
devices.

Operational Condition
Recovery
Rx_los is asserted by an

The port stays bypassed until rx_los is de-asserted. At that time, the port
insertion will be automatically retried. The port continues to stay bypassed until
the port can pass the port insertion criteria.

The switch automatically tries to re-insert the device, by sending F7 Initialization
notifications to the device connected to the bypassed port. The port continues to
stay bypassed until the device returns F7 Initialization notifications to the port
and passes the port insertion criteria.
