NIC Redundancy
The following NIC redundancy options are available, depending on the selected NIC mode and your platform:
• none—Each port associated with the configured NIC mode operates independently. The ports do not
fail over if there is a problem.
• active-active—If supported, all ports associated with the configured NIC mode operate simultaneously.
This increases throughput and provides multiple paths to the CIMC.
• active-standby—If a port associated with the configured NIC mode fails, traffic will fail over to one
of the other ports associated with the NIC mode.
If you select this option, make sure all ports associated with the configured NIC mode
are connected to the same subnet to ensure that traffic is secure regardless of which port
is used.
Note
The available redundancy modes vary depending on the selected network mode and your platform. For the
available modes, see the Hardware Installation Guide (HIG) for the type of server you are using. The C-Series
HIGs are available at the following URL: http://www.cisco.com/en/US/products/ps10493/prod_installation_

• Shared LOM—The LAN On Motherboard (LOM) Ethernet
host ports are used to access the CIMC.
If you select Shared LOM, make sure that all host
ports belong to the same subnet.
