•
Shared LOM
—
The 1-Gb Ethernet ports are used to access Cisco IMC. You must select a NIC redundancy
and IP setting.
•
Cisco Card
—
The ports on an installed Cisco UCS virtual interface card (VIC) are used to access Cisco
IMC. You must select a NIC redundancy and IP setting.
See also the required VIC Slot setting below.
•
VIC Slot
—
If you use the Cisco Card NIC mode, you 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, slot 1 is used.
◦
If you select Riser2, slot 2 is used.
◦
If you select Flex-LOM, you must use an mLOM-style VIC in the mLOM sl
NIC Redundancy
This server has the following NIC redundancy settings that you can choose from:
•
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.
•
Active-active
—
All Ethernet ports are utilized simultaneously. Shared LOM EXT mode can have only
this NIC redundancy setting. Shared LOM and Cisco Card modes can have both Active-standby and
Active-active settings.
The active/active setting uses Mode 5 or Balance-TLB (adaptive transmit load balancing). This is channel
bonding that does not require any special switch support. The outgoing traffic is distributed according
to the current load (computed relative to the speed) on each slave. Incoming traffic is received by the
current slave. If the receiving slave fails, another slave takes over the MAC address of the failed receiving
slave.
Upgrade the BIOS and Cisco IMC Firmware
The following procedure describes how to upgrade the BIOS and Cisco IMC firmware on Cisco SNS-3515
and SNS-3595 appliances. We recommend that you upgrade the BIOS and Cisco IMC to the latest version
that is available for download on Cisco.com.
To check the version of BIOS and Cisco IMC that is currently running on your appliance:
1
Launch
CIMC
.
2
Click
BIOS
.
The running version is listed under
BIOS properties
.
When you upgrade the BIOS firmware, you must also upgrade the Cisco IMC firmware to the same
version. Otherwise, the server will not boot.
