Advanced Autonegotiation
19
As with Port Monitoring, Advanced Autonegotiation also monitors port
error levels and provides notification, but goes further by changing a
port’s mode into full duplex mode. However, if errors continue to exceed
the system threshold, Advanced Autonegotiation partitions the port.
Configuration
Options
To provide flexibility, the Advanced Autonegotiation and Port Monitoring
features are enabled and disabled separately from standard
autonegotiation. The benefits of this arrangement include:
„
The Advanced Autonegotiation and Port Monitoring features can also
work for 100FX ports, which do not have an autonegotiation process.
„
Port Monitoring can be enabled for ports that have been set to
operate a fixed speed and duplex mode (autonegotiation is disabled).
Configuring Standard Autonegotiation
To enable or disable standard autonegotiation, at the CLI prompt, enter:
ethernet autoNegotiation
Then select a port or range of ports and enter either
enable
or
disable
.
Configuring a Fixed Port State
To set a fixed port state (standard autonegotiation is disabled), at the CLI
prompt, enter:

Then select a port or range of ports and enter the appropriate speed and
duplex mode.
Configuring Advanced Autonegotiation or Port Monitoring
To enable or disable either Advanced Autonegotiation or Port Monitoring,
