Z9332F-ON platform: OS10 supports 25G auto negotiation with third-party 25G NIC devices that comply with the IEEE
802.3by and 25G Ethernet Consortium standards. When you use a third-party NIC device that does not support the 25G
Ethernet Consortium standard, to bring up the port:
If you have enabled SmartAN technology on the server, disable auto negotiation on the OS10 switch port.
Otherwise, disable auto negotiation on both the OS10 switch port and the third-party link partner.
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
no shutdown
switchport access vlan 1
flowcontrol receive on
OS10(conf-if-eth1/1/50)# do show interface ethernet 1/1/50
