Server NICs
NIC Mode
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).
-
Shared LOM—Any LOM (LAN on Motherboard) port that can be used to access Cisco IMC.
-
Shared LOM Extended—Any LOM port or adapter card port that can be used to access Cisco IMC. The Cisco adapter card has to be installed in a slot with NCSI support.
Note
Shared LOM and Shared LOM Extended ports are available only on some C-series servers.
Note
For other UCS C-Series M4 and M5 servers, the NIC mode is set to Shared LOM Extended by default.
Default NIC Mode Setting:
-
For UCS C-Series C125 M5 servers and S3260 servers, the NIC Mode is set to Cisco Card by default.
NIC Redundancy
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.
Note
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.
-
None—In Dedicated mode, NIC redundancy is set to None.
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
