Setting the Management IP Address
This chapter includes the following sections:
Management IP Address
Each server in a Cisco UCS domain 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 domain. 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.

What to Do Next
If you have set the management IP address to static, configure a server to use a static IP address.
Configuring the Management IP Pool
Management IP Pool
The default management IP pool ext-mgmt 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.
All IP addresses in the
management IP pool must be in the same IPv4 subnet, or have the same IPv6
network prefix as the IP address of the fabric interconnect.
 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.
|
Configuring an IP Address Block for the Management IP Pool
The management IP pool must not contain any IP addresses that
have been assigned as static IP addresses for a server or service profile.
Procedure | Command or Action | Purpose |
---|
Step 1 | UCS-A#
scope org /
|
Enters root organization mode.
|
Step 2 | UCS-A /org #
scope ip-pool ext-mgmt
|
Enters organization IP pool mode.
Note
|
You cannot create (or delete) a management IP pool. You can only
enter (scope to) the existing default pool.
|
|
Step 3 | UCS-A /org/ip-pool #
set descr
description
| (Optional)
Provides a description for the management IP pool.
This description applies to all address blocks in the management IP pool.
Note
|
If your description includes spaces, special characters, or
punctuation, you must begin and end your description with quotation marks. The
quotation marks will not appear in the description field of any
show
command output.
|
|
Step 4 | UCS-A /org/ip-pool # set assignmentorder {default | sequential}
| This can be one of the following:
|
Step 5 | UCS-A /org/ip-pool # create block first-ip-addr last-ip-addr gateway-ip-addr subnet-mask
|
Creates a block (range) of IP addresses, and enters organization IP pool block mode. You must specify the first and last IP addresses in the address range, the gateway IP address, and subnet mask.
Note
|
An IP pool can contain more than one IP block.
To create multiple blocks, enter multiple
create block commands from organization IP pool mode.
|
|
Step 6 | UCS-A /org/ip-pool/block # set primary-dns ip-address secondary-dns ip-address
| Specifies the primary DNS and secondary DNS IP addresses.
|
Step 7 | UCS-A /org/ip-pool/block #
commit-buffer
|
Commits the transaction to the system configuration.
|
The following example configures an IP address block for the
management IP pool and commits the transaction:
UCS-A# scope org /
UCS-A /org # scope ip-pool ext-mgmt
UCS-A /org/ip-pool* # set descr "This is a management IP pool example."
UCS-A /org/ip-pool* # create block 192.168.100.1 192.168.100.200 192.168.100.10 255.255.255.0
UCS-A /org/ip-pool/block* # commit-buffer
UCS-A /org/ip-pool/block #
What to Do Next
Configure one or more service profiles or service profile
templates to obtain the CIMC IP address from the management IP pool.
