System Ip Addresses; Dhcp Requirements - Cisco UCS S3260 Service Manual

Initial System Setup

System IP Addresses

A Cisco UCS S3260 system can have up to five IP addresses:
All controllers present in the system must have IP addresses assigned in order to communicate with each
Note
other. All IP addresses can be assigned by your DHCP server, or you can assign static IP addresses.
•
•
•
•
•
The IP addresses for the management IP, the SIOC CMC IPs, and the server BMC IPs must all be
Note
configured on the same subnet.

DHCP Requirements

To configure the system remotely, you must have a DHCP server on the same network as the system.
Your DHCP server must be preconfigured with the range of MAC addresses for the chassis management
controller (CMC) in the system I/O controller (SIOC). Each SIOC has a range of six MAC addresses
assigned. The MAC address printed on the label defines the beginning of the range of six contiguous
MAC addresses.
The MAC address is printed on a label on the SIOC top cover.

Management IP—This is the overall system virtual IP address. You log into this address when you
access the system's Cisco IMC interface via your LAN connection to the active chassis management
controller in SIOC 1 or SIOC 2 (see
SIOC 1 CMC IP—This is the internal address for the chassis management controller (CMC) in
SIOC 1. This address can be assigned by your DHCP server, or you can set a static address by using
the Cisco IMC interface.
SIOC 2 CMC IP—This is the internal address for the CMC in SIOC 2 (if installed). This address
can be assigned by your DHCP server, or you can set a static address by using the Cisco IMC
interface.
Server 1 BMC IP—This is the internal address for the board management controller (BMC) in server
node 1. This address can be assigned by your DHCP server, or you can set a static address by using
the Cisco IMC interface.
Server 2 BMC IP—This is the internal address for the BMC in server node 2 (if installed). This
address can be assigned by your DHCP server, or you can set a static address by using the Cisco
IMC interface.
