Each server in a Cisco UCS instance must have a management IP address assigned to its Cisco Integrated Management Controller (CIMC) or to the service profile associated with the server. Cisco UCS Manager
uses this IP address for external
access that terminates in the CIMC.
This external access can be through one of
the following:
KVM console
Serial over LAN
An IPMI tool
The management IP address used to access the CIMC on a server can be one of the following:
A static IPv4 address assigned directly to the server.
A static IPv4 address assigned to a service profile. You cannot configure a service profile template with a static IP address.
An IP address drawn from the management IP address pool and assigned to a service profile or service profile template.
You can assign a management IP address to each CIMC on the server and to the service profile associated with the server. If you do so, you must use different IP addresses for each of them.
Note
You cannot assign a static IP address to a server or service profile if that IP address has already been assigned to a server or service profile in the Cisco UCS instance. If you attempt to do so, Cisco UCS Manager warns you that the IP address is already in use and rejects the configuration.
A management IP address that is assigned to a service profile moves with the service profile. If a KVM or SoL session is active when you migrate the service profile to another server, Cisco UCS Manager terminates that session and does not restart it after the migration is completed. You configure this IP address when you create or modify a service profile.

Management IP Pool
The management IP pool is a collection of external IP addresses.
Cisco UCS Manager
reserves each block of IP addresses in the management IP pool for external
access that terminates in the CIMC on a server.
You can configure service profiles and service profile templates to use IP addresses from the management IP pool. You cannot configure servers to use the management IP pool.
Note
The management IP pool must not contain any IP addresses that have been assigned as static IP addresses for a server or service profile.
