Introduction

This document describes how to configure the Localized Identity Services Engine (ISE) Installation to reinstall or upgrade ISE.

Prerequisites

Requirements

Cisco recommends that you have knowledge of these topics:

- Cisco ISE 3.X

- Virtual Machines

- Secure Network Server (SNS) Appliances

Components Used

- Identity Service Engine (ISE) 3.2 Patch 5

- Secure Transfer Protocol (FTP) server

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

Background Information

ISE can run as a Virtual Machine (VM) or on SNS server. Sometimes is need it to reinstall ISE due to a problem or for an upgrade process. Reinstalling ISE can become a challenge in some scenarios. For this reason, ISE 3.2 Patch 5 introduces a new feature that allows the user to reinstall ISE using the command line, saving around 40 minutes.

The feature is Localized ISE installation. On command line run the command application configure ise which displays this new option:

- [36] Localised ISE Install.

This means that to use this feature, ISE needs to be installed and running.

Another use of this feature is that you can use it to install a higher version. Consider this an upgrade option, just remember that this deletes all the configuration as it install ISE again, even the running-configuration.

Warning: You can use this option to reinstall the current version and higher versions. You cannot install a version that is older than the current version.

Configure

Step 1. Download the ISO

1. Navigate to ISE folder in the Download page, download the correct ISO.

1.1. If you are reinstalling ISE, download the same version.

1.2. If you are doing an upgrade, download the ISO you are doing the upgrade to.

2. Copy the ISO to the SFTP server.

Step 2. Configure a Repository

1. Log in to ISE command line.

2. Run the next commands:

#configure terminal

Entering configuration mode terminal

#repository iso

#url sftp://10.10.10.10/folder

% Warning: Repositories configured from CLI cannot be used from the ISE web UI and are not replicated to other ISE nodes.

If this repository is not created in the ISE web UI, it will be deleted when ISE services restart.

#user cisco password plain cisco

#exit

#exit

#crypto host_key add host 10.10.10.10

Note: This example is using a SFTP repository with ip address 10.10.10.10 with path /folder. Replace these values accordingly.

Step 3. Copy the ISO

1. Copy the ISO to the disk, run the command:

#copy repository iso file ise-3.2.0.542.SPA.x86_64.iso disk://

2. Validate the ISO is in the disk, run the command:

#dir

Directory of disk:/

Apr 09 2024 11:01:15 ise-3.2.0.542.SPA.x86_64.iso

Step 4. Reinstall the Software

1. Run the command application configure ise and type option 36.

2. Select the ISO.

3. Validate the MD5 value. You can take this value and compare it with the Download page.

4. If the MD5 value is correct, proceed to installation.

ISO files present in the disk are:

[1] ise-3.2.0.542.SPA.x86_64.iso

[2] ise-3.1.0.518b.SPA.x86_64.iso

Choose the ISO you want to install:  1

Computing MD5 hash value of the selected ISO...

File selected:ise-3.2.0.542.SPA.x86_64.iso (MD5: 2e609b6cbeaa5c360d0a09a2a5d3c564)

Warning: Verify the MD5 checksum of the ISO before you proceed.

Proceed with Installation? [y/n] y

Copying ISO contents to installer directories. The copy may take around 5 minutes.

% Notice: The appliance will reboot to install the chosen Cisco ISE release now.

Caution: Do not use the MD5 value in this example as the ISO file can be changed, even though, it says it is for ISE 3.2.

Always verify it in Download.

5. Check the console to monitor the installation.

Installation in Progress

Step 5. Finish the Installation

1. Once the installation has finished, it is time to do the running configuration. Type setup.
