Background Information
CIMC
Each server in a Cisco UCS domain must have one or more management IP addresses assigned
to its CIMC or to the service profile associated with the server. Cisco UCS Manager uses these IP
addresses for external access that terminates in the CIMC. This external access can be through
one of these services:
Keyboard/Video/Mouse (KVM) console
●
Serial over LAN
●
An IPMI tool
●
Out-Of-Band (OOB) Versus Inband
In earlier releases of UCS software, the management IP address that is used to access the CIMC
on a server could only be accessed OOB. In OOB, the traffic traverses the fabric interconnect via
the management port to the network.
Now with UCS Version 2.2, you are also able to access the CIMC via an inband address. Traffic to
and from the inband address traverses through the fabric interconnect via the fabric uplink port.
What can be configured with an inband address?
There are two options to configure inband access to a CIMC. Both configuration options are
outlined in the Configure section. You can configure:
Directly on the CIMC, which means the IP address stays with the server [Step 4].
●
On the Service Profile, which means the IP address stays with the service profile [Step 5].
●
Use the Same Uplink from Network Traffic for Inband Management
Alternatively, if you would like to use the same uplink ports for network traffic and inband
management, you can either:
Leave the VLAN group with no uplinks [Step 7]. The VLAN group does not require an uplink to
be created and all VLANs should still be trunked out of all available uplink ports.
●
Add all required VLANs to the VLAN group [Step 6]. Open VLAN manager and add the uplink
to each VLAN that you want it to trunk.

1. Configure an Inband IP Pool
This section outlines the process to create an IPv4 Address Pool from which the servers will be
assigned their Inband IPv4 addresses.
Navigate to LAN tab > IP Pools.
