In this NIC mode, DHCP replies are returned to both the shared LOM ports and the Cisco card ports. If the system
determines that the Cisco card connection is not getting its IP address from a Cisco UCS Manager system because
the server is in standalone mode, further DHCP requests from the Cisco card are disabled. Use the Cisco Card NIC
mode if you want to connect to Cisco IMC through a Cisco card in standalone mode.
• Shared LOM—The 1-Gb/10-Gb Ethernet ports are used to access Cisco IMC. You must select either the Active-Active
or Active-standby NIC redundancy setting in the following step.
• Dedicated—The dedicated management port is used to access Cisco IMC. You must select the None NIC redundancy
setting in the following step.
• Cisco Card—The ports on an installed Cisco UCS Virtual Interface Card (VIC) are used to access the Cisco IMC.
You must select either the Active-Active or Active-standby NIC redundancy setting in the following step.
See also the required VIC Slot setting below.
• VIC Slot—Only if you use the Cisco Card NIC mode, you must select this setting to match where your VIC is
installed. The choices are Riser1, Riser2, or Flex-LOM (the mLOM slot).
◦
If you select Riser1, you must install the VIC in slot 1.
◦
If you select Riser2, you must install the VIC in slot 2.
◦
If you select Flex-LOM, you must install an mLOM-style VIC in the mLOM slot.
Step 2
Set the NIC redundancy to your preference. This server has three possible NIC redundancy settings:
• None—The Ethernet ports operate independently and do not fail over if there is a problem. This setting can be used
only with the Dedicated NIC mode.
• Active-standby—If an active Ethernet port fails, traffic fails over to a standby port. Shared LOM and Cisco Card
modes can each use either Active-standby or Active-active settings.
• Active-active (default)—All Ethernet ports are utilized simultaneously. The Shared LOM EXT mode must use only
this NIC redundancy setting. Shared LOM and Cisco Card modes can each use either Active-standby or Active-active
settings.
Step 3
Choose whether to enable DHCP for dynamic network settings, or to enter static network settings.
Before you enable DHCP, you must preconfigure your DHCP server with the range of MAC addresses for this
server. The MAC address is printed on a label on the rear of the server. This server has a range of six MAC
addresses assigned to Cisco IMC. The MAC address printed on the label is the beginning of the range of six
contiguous MAC addresses.
Note
The static IPv4 and IPv6 settings include the following:
•
The Cisco IMC IP address.
For IPv6, valid values are 1 - 127.
•
The gateway.
For IPv6, if you do not know the gateway, you can set it as none by entering :: (two colons).
•
The preferred DNS server address.
For IPv6, you can set this as none by entering :: (two colons).
