Layer 2 Switching Commands 393
Default Configuration
Auto-negotiation is enabled by default on copper ports.
Command Mode
Interface Configuration (Ethernet) mode
User Guidelines
When both speed and duplex are configured to auto, auto negotiation is
enabled for the port. To disable auto-negotiation on a port, it is necessary to
enter either the speed or duplex commands without using the auto
parameter. 10G/40G fiber ports do not support auto-negotiation and
therefore require the operator to enter the duplex full command and the
speed command with the desired operating bandwidth. Auto-negotiation is
required on 1G/10G/40G copper ports and 1G fiber ports.
The duplex command is only available on the Dell EMC Networking N1500
Series switches. Other switch models support full duplex operation only.
Example
The following example configures the duplex operation of TenGigabit
Ethernet port Te 1/0/5 to force full duplex operation, disable auto-
negotiation, and set the speed to 1000M.
console(config)# interface te1/0/5
console(config-if-Te1/0/5)# duplex full
console(config-if-Te1/0/5)# speed 1000
flowcontrol
Use the flowcontrol command in Global Configuration mode to configure
the flow control. To disable flow control, use the no form of this command.
Syntax

Default Configuration
