• None—The Ethernet ports operate independently and do not fail over if there is a problem. This setting

can be used only with the Dedicated NIC mode.

• Active-standby—If an active Ethernet port fails, traffic fails over to a standby port. Shared LOM and

Cisco Card modes can each use either Active-standby or Active-active settings.

• Active-active (default)—All Ethernet ports are utilized simultaneously. The Shared LOM EXT mode

must use only this NIC redundancy setting. Shared LOM and Cisco Card modes can each use either

Active-standby or Active-active settings.

Updating the BIOS and Cisco IMC Firmware

When you upgrade the BIOS firmware, you must also upgrade the Cisco IMC firmware to the same version,

or the server does not boot. Do not power off the server until the BIOS and Cisco IMC firmware are matching

or the server does not boot.

Cisco provides the Cisco Host Upgrade Utility to assist with simultaneously upgrading the BIOS, Cisco IMC,

and other firmware to compatible levels.

Caution

The server uses firmware obtained from and certified by Cisco. Cisco provides release notes with each firmware

image. There are several possible methods for updating the firmware:

• Recommended method for firmware update: Use the Cisco Host Upgrade Utility to simultaneously

upgrade the Cisco IMC, BIOS, and component firmware to compatible levels.

See the Cisco UCS C-Series Rack-Mount Server Configuration Guide.

• You can upgrade the Cisco IMC and BIOS firmware by using the Cisco IMC CLI interface.
