Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
◆ 1000BASE-T does not support forced mode. Auto-negotiation should always be
used to establish a connection over any 1000BASE-T port or trunk.
◆ 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.
Example
The following example configures port 10 to use auto-negotiation.
Console(config)#interface ethernet 1/10
Console(config-if)#negotiation
Console(config-if)#
