Local indications –
Cause The auto-negotation function has failed to find a common technology with the
remote Ethernet equipment. This common technology can be 10Base-T half
duplex, 10Base-T full duplex, or 100Base-T half duplex.
Actions Force manually either or both ends of the link into a specific common
technology.
Note(s) When the auto-negotiation function is disabled, then the common technology
used is 10Base-T half duplex.
The common technology also depends on the type of Ethernet interface. On
optical Ethernet interfaces for example, always Gigabit Ethernet in full duplex
mode (1000Base-X full duplex) is assumed.
