SMC Networks 100BASE-TX, 16 10BASE-T 4-106, negotiation

Command Line Interface

4-106

4

Default Setting

• Auto-negotiation is enabled by default.

• When auto-negot iation is disabled, the default speed-duple x setting is 100half

for 100BASE-TX ports and 1000full for Gigabit Ethernet ports.

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-negotiat ion on

the selected interface.

• When using th e 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 mu st be

specified in the capabilities list for an interface.

Example

The following example configures port 5 to 10 0 Mbps, half-duplex operation.

Related Commands

This command enables autonegotiation for a given interface. Use the no form to

disable autonegotiation.

Syntax

[no] negotiation

Default Setting

Enabled

Command Mode

Interface Configuration (Ethernet, Port Channel)

Command Usage

• When auto-negotiation is enabled the switch will negotiate the best settings

for a link based on the capabilities command. When auto-negotiation is

disabled, you must manually specify the link attributes with the speed-duplex

and flowcontrol commands.

Console(config)#interface ethernet 1/5

Console(config-if)#speed-duplex 100half

Console(config-if)#no negotiation
