Note

Cisco SNS hardware appliances support the Unified Extensible Firmware Interface (UEFI) secure boot feature. This feature ensures that only a Cisco- signed ISE image can be installed on the SNS hardware appliances, and prevents installation of any unsigned operating system even with physical access to the device. For example, generic operating systems, such as Red Hat Enterprise Linux or Microsoft Windows cannot boot on this appliance.The SNS 3515 and SNS 3595 appliances support only Cisco ISE 2.0.1 or later releases. You cannot install a release earlier than 2.0.1 on the SNS 3515 or SNS 3595 appliance.

  • Use the Cisco Integrated Management Controller (Cisco IMC) interface to map the installation .iso file to the virtual DVD device.
  • Create an install DVD with the installation .iso file plug in a USB external DVD drive and boot the appliance from the DVD drive.
  • Create a bootable USB device using the installation .iso file and boot the appliance from the USB drive.

VMware Virtual Machine

Note

The VMware form factor instructions provided in this document are applicable for Cisco ISE installed on Cisco Hyperflex as well.

Virtual Machine Resource and Performance Checks

Before installing Cisco ISE on a virtual machine, the installer performs hardware integrity checks by comparing the available hardware resources on the virtual machine with the recommended specifications.
During a VM resource check, the installer checks for the hard disk space, number of CPU cores allocated to the VM, CPU clock speed, and RAM allocated to the VM. If the VM resources do not meet the basic evaluation specifications, the installation terminates. This resource check is applicable only for ISO- based installations. When you run the Setup program, a VM performance check is done, where the installer checks for disk I/O performance. If the disk I/O performance does not meet the recommended specifications, a warning appears on the screen, but it allows you to continue with the installation.

  • The VM performance check is done periodically (every hour) and the results are averaged for a day. If the disk I/O performance does not meet the recommended specification, an alarm is generated.
  • The VM performance check can also be done on demand from the Cisco ISE CLI using the show tech-support command.
  • The VM resource and performance checks can be run independently of Cisco ISE installation. You can perform this test from the Cisco ISE boot menu.

Install Cisco ISE on VMware Virtual Machine Using the ISO File

This section describes how to install Cisco ISE on a VMware virtual machine using the ISO file.

Prerequisites for Configuring a VMware ESXi Server

Review the following configuration prerequisites listed in this section before you attempt to configure a VMWare ESXi server:

  • Remember to log in to the ESXi server as a user with administrative privileges (root user).
  • Cisco ISE is a 64-bit system. Before you install a 64-bit system, ensure that Virtualization Technology (VT) is enabled on the ESXi server.
  • Ensure that you allocate the recommended amount of disk space on the VMware virtual machine.
  • If you have not created a VMware virtual machine file system (VMFS), you must create one to support the Cisco ISE virtual appliance. The VMFS is set for each of the storage volumes configured on the VMware host. For VMFS5, the 1-MB block size supports up to 1.999 TB virtual disk size.

Virtualization Technology Check

If you have an ESXi server installed already, you can check if Virtualization Technology is enabled on it without rebooting the machine. To do this, use the Excel-info command. Here is an example:
Cisco-SNS- 3515-Identity-Services-Engine-fig-1

  • If HV Support has a value of 3, then VT is enabled on the ESXi server and you can proceed with the installation.
  • If HV Support has a value of 2, then VT is supported, but not enabled on the ESXi server. You must edit the BIOS settings and enable VT on the server.

Enable Virtualization Technology on an ESXi Server
