NIC Modes and NIC Redundancy Settings
NIC Modes
This server has the following NIC mode settings that you can choose from:
• Shared LOM EXT (default)—This mode is the shared LOM extended mode that is the
factory-default setting. With 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.
• Dedicated—The dedicated management port is used to access Cisco IMC. You must select a NIC
redundancy and IP setting.
• Shared LOM—The 1-Gb Ethernet ports are used to access Cisco IMC. You must select a NIC
redundancy and IP setting.
• Cisco Card—The ports on an installed Cisco UCS virtual interface card (VIC) are used to access
Cisco IMC. You must select a NIC redundancy and IP setting.
See also the required VIC Slot setting below.
• VIC Slot—If you use the Cisco Card NIC mode, you select this setting to match where your VIC is
installed. The choices are Riser1, Riser2, or Flex-LOM (the mLOM slot).
– If you select Riser1, slot 2 is the primary slot, but you can also use slot 1.
– If you select Riser2, slot 5 is the primary slot, but you can also use slot 4.
– If you select Flex-LOM, you must use an mLOM-style VIC in the mLOM slot.
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 can be used only with the Dedicated NIC mode.
– 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 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 slave.
Incoming traffic is received by the current slave. If the receiving slave fails, another slave takes
over the MAC address of the failed receiving slave.
