Setting the Management IP Address

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.

          Setting the Management IP Address on a Service Profile

          Procedure
            Step 1   In the Navigation pane, click the Servers tab.
            Step 2   On the Servers tab, expand Servers > Service Profiles.
            Step 3   Expand the node for the organization that contains the service profile for which you want to set the management IP address.

            If the system does not include multitenancy, expand the root node.

            Step 4   Click the service profile for which you want to set the management IP address.
            Step 5   In the Work pane, click the General tab.
            Step 6   In the Actions area, click Change Management IP Address.
            Step 7   In the Change Management IP Address dialog box, select one of the following:
            • None—No management IP address is assigned to the server through the service profile. The management IP address is based on the CIMC management IP address defined on the server.
            • Static—The service profile assigns a static management IP address to the associated server. If the service profile is migrated to a new server, the management IPv4 address moves with the service profile. Cisco UCS Manager GUI displays the Static IP Address area that lets you define the static IP address.
            • IP-pool-name—The service profile assigns a management IP address from the selected IP pool to the associated server. Click Create IP Pool to create a global pool of IP addresses that can be used by all service profiles and service profile templates.
            Step 8   If you selected Static, complete the following fields:
            Name Description

            IP Address field

            The management IP address assigned to the server through the service profile.

            Step 9   Click Save Changes.

            Setting the Management IP Address on a Service Profile Template

            Procedure
              Step 1   In the Navigation pane, click the Servers tab.
              Step 2   On the Servers tab, expand Servers > Service Profile Templates.
              Step 3   Expand the node for the organization that contains the service profile template for which you want to set the management IP address.

              If the system does not include multitenancy, expand the root node.

              Step 4   Click the service profile template for which you want to set the management IP address.
              Step 5   In the Work pane, click the General tab.
              Step 6   Expand the Management IP Address area.
              Step 7   In the Management IP Address Policy field, click one of the following radio buttons:
              • None—No management IP address is assigned to the server through the service profile. The management IP address is based on the CIMC management IP address defined on the server.
              • Pooled—The service profile assigns a management IP address from the pool shown in Pool Name to the associated server. If the service profile is migrated to a new server, the management IP address moves with the service profile.
              Step 8   Click Save Changes.

              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.


              Creating an IP Address Block in 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
                Step 1   In the Navigation pane, click the LAN tab.
                Step 2   In the LAN tab, expand LAN > Pools > Organization_Name .
                Step 3   Expand the IP Pools node.
                Step 4   Right-click IP Pool ext-mgmt and select Create Block of IP Addresses.
                Step 5   In the Create a Block of IP Addresses dialog box, complete the following fields:
                Name Description

                From field

                The first IP address in the block.

                Size field

                The number of IP addresses in the pool.

                Subnet Mask field

                The subnet mask associated with the IP addresses in the block.

                Default Gateway field

                The default gateway associated with the IP addresses in the block.

                Primary DNS field

                The primary DNS server that this block of IP addresses should access.

                Secondary DNS field

                The secondary DNS server that this block of IP addresses should access.

                Step 6   Click OK.

                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.

                Deleting an IP Address Block from the Management IP Pool

                Procedure

                  Step 2   In the LAN tab, expand LAN > Pools > Organization_Name .
                  Step 3   Expand the IP Pools node.
                  Step 4   Select IP Pool ext-mgmt.
                  Step 5   Right-click the IP address block that you want to delete and select Delete.
                  Step 6   If the Cisco UCS Manager GUI displays a confirmation dialog box, click Yes.
