Instructions to reconfigure a Catalyst Center appliance and update its settings using Configuration wizard.

To reconfigure an appliance and update its settings, you must use the Configuration wizard. You cannot use the Linux CLI to do this. The normal Linux administration procedures that you might use to update configuration settings on a standard Linux server will not work and should not be attempted.

After the appliance is configured, you cannot use the Configuration wizard to change all the appliance settings. Changes are restricted to the following settings only:

  • Host IP address of the appliance

  • DNS server IP addresses

  • Default gateway IP address

  • NTP server IP addresses

  • Cluster Virtual IP address

  • Cluster hostname (FQDN)

  • Static routes

  • Proxy server IP address

  • Maglev user password

  • Admin user password

  • NIC bonding enablement

Before you begin

You need the Linux username (maglev ) and password that are currently configured on the target appliance.

Procedure

1.

Point your browser to the Cisco IMC IP address you set during the Cisco IMC GUI configuration that you performed, and log in to the Cisco IMC GUI as the Cisco IMC user (see Enable browser access to Cisco Integrated Management Controller).

After successful login, the appliance displays the Cisco Integrated Management Controller Chassis Summary window, with a hyperlinked menu at the top of the window, as shown below.
Cisco Integrated Management Controller CHassis summary window, showing dropdown with Java based KVM and HTML Based KVM.
2.

In the hyperlinked menu, choose Launch KVM and then select either Java based KVM or HTML based KVM. If you select Java-based KVM, you need to launch the Java startup file from your browser or file manager in order to view the KVM console in its own window. If you select HMTL-based KVM, it launches the KVM console in a separate window or tab automatically.

Irrespective of the KVM type you choose, use the KVM console to monitor the progress of the configuration and respond to the Maglev Configuration wizard prompts.
3.

When prompted, enter the Linux password.

4.

Enter the following command to access the Configuration wizard.

sudo maglev-config update

Catalyst Center 2.3.7.7 onwards:

  • Change the maglev user password by specifying a new one in the Linux Password and Re-enter Linux Password fields. Ensure that this password complies with the requirements described in Password requirements. Leave these fields blank to continue using the current password.

  • You can make the other configuration setting changes without entering the maglev user password.
5.

The Configuration wizard presents an abbreviated version of the same series of screens shown in, for example, Configure a secondary node using the Maglev wizard. Make changes to the settings presented, if required. After you finish making changes on each screen, choose [Next], as needed, to proceed through the Configuration wizard.
6.

At the end of the configuration process, a message appears, stating that the Configuration wizard is now ready to apply your changes. The following options are available:

  • [back]: Review and verify your changes.

  • [cancel]: Discard your changes and exit the Configuration wizard.

  • [proceed]: Save your changes and begin applying them.

Choose proceed>> to complete the installation. The Configuration wizard applies the changes you made.

At the end of the configuration process, a CONFIGURATION SUCCEEDED! message appears.
