In Cisco ISE the WebGUI and CLI admin accounts/passwords are separate. In order to change the passwords you can use the following methods:
- The CLI Admin password can be changed from the CLI by entering the command password. The CLI password is unique to each ISE node
- The WebGUI password can be changed from the CLI by entering the command application reset-passwd ise admin. The WebGUI password must be reset on the Primary PAN, this password is then synchronised to all ISE nodes.

The intention of this blog post is to describe the steps to configure certificate authentication for FlexVPN on a Cisco IOS router. This post will not describe all the steps to enrol for a certificate or all the steps to configure FlexVPN, refer to the previous blog posts list below.
The configuration used is based on the FlexVPN sVTI blog post below and has successfully enrolled for certificates on all routers. VPN connectivity has been established using PSK, the configuration below will convert from PSK to certificate authentication.
Requesting a certificate on Cisco IOS router using SCEP or manual enrolment
Configuring FlexVPN VTI and Hub-and-Spoke on Cisco routers
Configure FlexVPN for Certificate authentication
All certificates in this FlexVPN lab are signed by the CA called lab-PKI-CA
Run the command show crypto pki certificates to identify the issuer, in this instance lab-PKI-CA

The intention of this blog post is to describe how to configure a Cisco IOS router to request a certificate from a Microsoft SCEP (NDES) server to use for VPN authentication. A Windows Server must be configured as a Certificate Authority and with “Network Device Enrollment Service”. In the lab a Windows 2008 R2 server is configured as a Domain Controller, CA and NDES server – in production these roles would ideally located on separate servers.
Windows Server Configuration
Open the Certificate Templates Console
Right click to Duplicate the IPSec (Offline request) template
Select Windows Server 2008 Enterprise, click OK
Change the display name to IOSTemplate
Click Application Policies
Click Edit and
add Client Authentication

The Device Sensor feature on Cisco Catalyst switches can be used for profiling on ISE. It collects additional information about endpoints connected to the switch using LLDP, CDP and DHCP protocols which other ISE Probes may not collect. The endpoint information is encapsulated in a RADIUS accounting packet and then forwarded to ISE. The Device Sensor utilises the ISE RADIUS Probe that should be enabled as default, therefore no additional probes need enabling.

This post describes how to configure a Cisco IOS Router with WebVPN. Cisco ISE (v2.1) will be used as a RADIUS server, to provide authentication and authorization. For testing purposes group membership will be used to determined which RADIUS attributes will be pushed to the connecting client.
RADIUS Server Configuration
For authorization Admin users will be permitted to use split tunnel, these configuration settings will be controlled centrally and pushed to the clients if they pass authorization.
Step 1 – Define Network Device
Add the Router as a Network Device, ensure to enter the shared secret password, this must match the shared secret configured on the router.

When using a Cisco ASA with the AnyConnect VPN Client software in some instances it is useful to assign the same static IP address to a client whenever they connect to the VPN. Within Active Directory you can configure per user a static IP address and use this IP address whenever the user connects to the VPN. The RADIUS Server (in this instance Cisco ISE 2.0) can be configured to query the attribute in AD which is the” msRADIUSFramedIPAddress” value and assign to the client whenever they connect.
This blog post describes the steps to modify the configuration of ASA/ISE/AD and assumes the Cisco ASA is already properly configured and users can successfully authenticate using the AnyConnect VPN client and receive an IP address from the IP Address Pool. Cisco ISE is defined as the RADIUS Server with Active Directory defined as the External Identity Source.

The purpose of this blog post is to document the configuration steps required to configure Wired 802.1x and MAB authentication on Cisco Catalyst switches using Cisco ISE 2.0 as the RADIUS server. ISE will be configured to use Microsoft AD as the External Identity Store to authenticate the users and computer onto the AD domain.
The switch is already configured for VLAN, Routing etc and any device plugged into the switch will be able to access the network. Basic ISE functionality has already been configured (integration with AD/PKI).
