This server has the following NIC redundancy settings that you can choose from:

OL-32062-01

Dedicated—The dedicated management port on system I/O controller 1 (SIOC 1) is used to access

the Cisco IMC. You must select a NIC redundancy and IP setting. This is the factory-default setting.

Shared LOM—Not supported at this time.

Cisco Card—The ports on an installed network adapter card are used to access the Cisco IMC. You

must select a NIC redundancy and IP setting.

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. This setting can be used only

–

with the Cisco Card NIC mode.

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.
