Setting the media type
All interfaces on the BIG-IP system default to auto-negotiate speed and
duplex settings. We recommend that you configure any network equipment
that you plan to use with the BIG-IP system to auto-negotiate speed and
duplex settings. If you connect the BIG-IP system to network devices with
forced speed and duplex settings, you must force the speed and duplex
settings of the BIG-IP system to match the settings of the other network
device.
WARNING
If the BIG-IP system is attempting to auto-negotiate interface settings with
an interface that has the speed and duplex settings forced, you will
experience severe performance degredation.
Use the following syntax to set the media type:
b interface <if name list> media <media type> | auto
The valid media types for this command are:
• 10baseT <duplex>
• 100baseTX <duplex>
• 1000baseFX full
• auto
To view the valid media types for an interface, type the following command:
b interface <if name list> media show
Important
In all Gigabit Ethernet modes, the only valid duplex mode is full duplex.
Setting the duplex mode
You can set duplex mode to full or half duplex. If the media type does not
accept the duplex mode setting, an onscreen message indicates this. If media
type is set to auto, or if the interface does not accept the duplex mode
setting, the duplex setting is not saved to /config/bigip_base.conf.
Use the following syntax to set the duplex mode:
b interface <if_name> duplex full | half
