Configuring Server NICs

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.

Note 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.

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_ guides_list.html

Sets the NIC mode to one of the following:

•Dedicated—The management Ethernet port is used to access the CIMC.

•Shared LOM—The LAN On Motherboard (LOM) Ethernet host ports are used to access the CIMC.

Note If you select Shared LOM, make sure that all host ports belong to the same subnet.

•Shared LOM 10G—The 10G LOM Ethernet host ports are used to access the CIMC.
