To force negotiation, use the following command:

negotiation on

To disable negotiation, use the following command:

negotiation off

To reset the negotiation mode to the default setting of the media you use, use one of the following commands:

negotiation auto

no negotiation

The following examples show that the nondefault configuration is added to the running configuration:

OS10(conf-if-eth1/1/50)# negotiation off
OS10(conf-if-eth1/1/50)# show configuration
!
interface ethernet1/1/50
 no shutdown
 switchport access vlan 1
 negotiation off
 flowcontrol receive on
OS10(conf-if-eth1/1/50)# negotiation on
OS10(conf-if-eth1/1/50)# show configuration
!
interface ethernet1/1/50
 no shutdown
 switchport access vlan 1
 negotiation on
 flowcontrol receive on

The following examples show that the default configuration is not added to the running configuration:

OS10(conf-if-eth1/1/50)# negotiation auto
OS10(conf-if-eth1/1/50)# show configuration
!
interface ethernet1/1/50
 no shutdown
 switchport access vlan 1
 flowcontrol receive on

The following example shows that the no negotiation command resets the interface to the default setting of the media used.

OS10(conf-if-eth1/1/50)# no negotiation 
OS10(conf-if-eth1/1/50)# show configuration
!
interface ethernet1/1/50
