• Auto-negotiation cannot be disabled for Gigabit Ethernet ports, which
only operate at 1000full (1 Gbps full-duplex).
• When auto-negotiation is enabled, the ECN330-switch negotiates the
best settings for a link based on the available capabilities advertised by
the interface. An interface’s advertised capabilities can be configured
using the capabilities command. When auto-negotiation is
disabled for Fast Ethernet ports, link attributes must be manually
specified using the speed-duplex and flowcontrol commands.
• If auto-negotiation is disabled for Fast Ethernet ports, auto-MDI/MDI-X
pin signal configuration will also be disabled for the RJ45 ports.
Example
The following example configures port 11 to use auto-negotiation.
