Command Usage
When auto-negotiation is enabled with the negotiation command, the
switch will negotiate the best settings for a link based on the capabilites
command. When auto-negotiation is disabled, you must manually
specify the link attributes with the speed-duplex and flowcontrol
commands.
Example
The following example configures Ethernet port 5 capabilities to 100half,
100full and flow control.

IEEE 802.3x for full-duplex operation.
• When using the negotiation command to enable auto-negotiation, the
