5.6.2 Negotiating with a Non-AutoNegotiation Capable Device
When the controller has AutoNegotiation enabled and the remote device
to which it is connected has the AutoNegotiation disabled (or does not
have AutoNegotiation capability at all), the controller stays in the link fail
state and continually restarts AutoNegotiation because it cannot
complete a negotiation sequence successfully. Conversely, the remote
device goes to the link pass state because it sees the AutoNegotiation
words transmitted to it as valid idle symbols. For proper operation
between two devices, the controller and the remote device must both be
either set with AutoNegotiation enabled or set with AutoNegotiation
disabled.
5.7 Management Counters
The controller management counters provide the necessary statistics to
completely support the following IETF and IEEE specifications:
• IETF RFC 1757:
• IETF RFC 1213 and 1573
• IETF RFC 1643:
• IEEE 802.3/Cl. 30:
RMON Statistics Group
SNMP Interfaces Group
Ethernet-Like MIB
Ethernet MIB
A complete list of the counters along with their definitions was already
defined in Table 2.14. A map of the actual MIB objects from the IETF
and IEEE specifications to the specific controller counters is shown
below in Table 5.5–Table 5.8.
