Overview

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 configuring the appliance, use the Configuration wizard only to change this limited set of appliance setting:

  • 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 set during the Cisco IMC GUI configuration and log in to the Cisco IMC GUI as the Cisco IMC user (see Enable browser access to the Cisco Integrated Management Controller).

After you log in, the appliance shows the Cisco Integrated Management Controller Chassis Summary window.
2.

In the hyperlinked menu at the top of the window, select Launch KVM and then select HTML based KVM.

The KVM console opens in a separate window or tab automatically. Use it to monitor the progress of the configuration and respond to the Maglev Configuration wizard prompts.
3.

When prompted, enter the Linux password.

4.

Enter this command to access the Configuration wizard.

sudo maglev-config update

In 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 provides an abbreviated version of the series of screens shown in, for example, Configure a secondary node using the Maglev wizard. Make changes to the settings provided, if required. After you finish making changes on each screen, select [Next], as needed, to continue 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. These 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.

Select proceed>> to complete the installation. The Configuration wizard applies your changes.

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