NIC Modes
This server has the following NIC mode settings that you can choose from:
• Shared LOM EXT (default)—This is the Shared LOM extended mode, the factory-default setting. With
• Dedicated—The dedicated management port is used to access Cisco IMC. You must select a NIC
• Shared LOM—The 1-Gb Ethernet ports are used to access Cisco IMC. You must select a NIC redundancy
• Cisco Card—The ports on an installed Cisco UCS virtual interface card (VIC) are used to access Cisco
• VIC Slot—If you use the Cisco Card NIC mode, you select this setting to match where your VIC is
NIC Redundancy
This server has the following NIC redundancy settings that you can choose from:
• None—The Ethernet ports operate independently and do not fail over if there is a problem. This setting
• Active-standby—If an active Ethernet port fails, traffic fails over to a standby port.
• Active-active—All Ethernet ports are utilized simultaneously. Shared LOM EXT mode can have only

this mode, the shared LOM and Cisco Card interfaces are both enabled.
In this mode, DHCP replies are returned to both the shared LOM ports and the Cisco card ports. If the
system determines that the Cisco card connection is not getting its IP address from a Cisco UCS Manager
system because the server is in standalone mode, further DHCP requests from the Cisco card are disabled.
If the system determines that the Cisco card connection is getting its IP address from a Cisco UCS
Manager system, the reply has parameters that automatically move the server to UCSM mode.

this NIC redundancy setting. Shared LOM and Cisco Card modes can have both Active-standby and
Active-active settings.
The active/active setting uses Mode 5 or Balance-TLB (adaptive transmit load balancing). This is channel
bonding that does not require any special switch support. The outgoing traffic is distributed according
to the current load (computed relative to the speed) on each standby. Incoming traffic is received by the
current standby. If the receiving standby fails, another standby takes over the MAC address of the failed
receiving standby.
