• 10full - Forces 10 Mbps full-duplex operation
• 10half - Forces 10 Mbps half-duplex operation
Default Setting
• Auto-negotiation is enabled by default.
• When auto-negotiation is disabled, the default speed-duplex setting is:
- Gigabit Ethernet ports – 1000full (1 Gbps full-duplex)
- 10 Gigabit Ethernet ports – 10000full (10 Gbps full-duplex)
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
• To force operation to the speed and duplex mode specified in a
speed-duplex command, use the no negotiation command to
disable auto-negotiation on the selected interface.
• When using the negotiation command to enable auto-negotiation,
the optimal settings will be determined by the capabilities command.
To set the speed/duplex mode under auto-negotiation, the required
mode must be specified in the capabilities list for an interface.
• The 1000BASE-T standard does not support forced mode.
Auto-negotiation must always be used to establish a connection over
any 1000BASE-T port or trunk.
Example
The following example configures port 5 to 100 Mbps, half-duplex
operation.
