The NIC mode setting determines which ports can reach the Cisco IMC. The following network mode options are available, depending on your platform:
Dedicated—The management port that is used to access the Cisco IMC.
Cisco Card—Any port on the adapter card that can be used to access the Cisco IMC. The Cisco adapter card has to be installed in a slot with Network the Communications Services Interface protocol support (NCSI).
The following NIC redundancy options are available, depending on the selected NIC mode and your platform:
active-active—If supported, all ports that are associated with the configured NIC mode operate simultaneously. This feature increases throughput and provides multiple paths to the Cisco IMC.
active-standby—If a port that is associated with the configured NIC mode fails, traffic fails over to one of the other ports associated with the NIC mode.
If you choose this option, make sure that 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.
