Which NIC redundancy modes allow the LOMs to be discovered by the operating system or hypervisor?
Which NIC redundancy modes allow the LOMs to be discovered by the operating system or
hypervisor?
Dedicated isn’t a redundancy mode – Anyone know the real answer?
From config guide:
Ethernet ports must be grouped together in a block. For each module (fixed or expansion), the Ethernet port block must start with the first port and end with an even numbered port.
NIC Mode drop-down list
– Dedicated—The management port is used to access the CIMC.
– Shared LOM—The LOM (LAN On Motherboard) ports are used to access the CIMC.
– Shipping—The out-of-the-box defaults will be used for all options.
NIC Redundancy drop-down list
– None—Each port associated with the configured NIC mode operates independently. The ports do not failover if there is a problem. This is option is only available if the NIC mode is set to Shipping.
– 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 failover to one of the other ports associated with the NIC mode.

default config is Shared LOM ext, Active/Active, DHCP enabled
So the correct answer is B
Correct answer should be option “B”
The question is, which nic redundancy mode allow the LOMs to be discovered by the operations system or hypervisor. So only if you choose dedicated mode you can use the LOMs for the OS, otherwise the LOMs are for CIMC-Access only. i think so…
NIC Mode
The NIC mode setting determines which ports can reach the CIMC. The following network mode options are
available, depending on your platform:
• Dedicated—The management port is used to access the CIMC.
• Shared LOM—Any LOM (LAN On Motherboard) port can be used to access the CIMC.
• Shared LOM 10G—Any 10G LOM port can be used to access the CIMC. This option is only available
for some adapter cards.
• Cisco Card—Any port on the adapter card can be used to access the CIMC. The Cisco adapter card has
to be installed in a slot with Network Communications Services Interface protocol (NCSI) support.
• Shared LOM Extended—Any LOM port or adapter card port can be used to access the CIMC. The
Cisco adapter card has to be installed in a slot with NCSI support.

OL-23489-08 61NIC 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 ofserver 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
Shared LAN on Motherboard (LOM) ports on the rack server are used exclusively for carrying management traffic. A separate cable connected to one of the ports on the PCIe card carries the data traffic. Using two separate cables for managing data traffic and management traffic is also referred to as dual-wire management.
….
The LOM ports on Cisco UCS C-Series Rack-Mount Servers integrated with Cisco UCS Manager can not be used for data traffic.

So i think the correct is A – Dedicated mode, In this mode we have only “None” redundency settings.
