Cisco IOS Radius Authentication with Windows Server 2. NPSConfiguring Cisco devices to authenticate management users via RADIUS is a great way to maintain a centralized user management base. Traditionally this has been done using the Cisco Access Control Server ACS which of course is fairly expensive and is typically out of the price range for most small medium sized businesses. If you are like most businesses you may already have an Active Directory infrastructure deployed and thus you already have the necessary software and licenses required to setup a basic RADIUS server using Network Policy Server NPS which can be used to authenticate network administrators on your Cisco IOS equipment for management purposes. The main benefit you get from RADIUS authentication is a centralized management console for user authentication and the ability to control which users have access to the Cisco CLI.

Such as disabling a user account in AD would result in failed authentication attempts for that username when attempting to log into a Cisco device. Also if you have a new employee, you can easily give their username access to Cisco network devices just by adding them into a Security Group in active directory.

These users will be used to verify the configuration and operational status of NPS. Once you have completed the basic Active Directory configuration you can move on to the NPS config. Please note that the Security Groups can be named whatever you like. Windows Network Policy Server Configuration. Prior to configuring NPS it must first be installed and authorized in Active Directory. To install NPS add the Network Policy and Access Services role to your server. After you have authorized NPS in Active Directory youre ready to add the first RADIUS Client. To add the client you must expan the RADIUS Clients and Servers line and right click on RADIUS Clients and click NEW. Youll be prompted to enter the Friendly Name and Address, IP address and Shared Secret. Enter this information as required. For this blog were using R1 which had the IP address of 1. CISCO as shown below Note that ND is used as a prefix to the device friendly name, this will be used later in the configuration of the NPS Policy which can identify network devices. Next, click the Advanced Tab across the type and select Cisco as the vendor name from the drop down list and click ok If you added the client correctly you should see the client friendly name, IP address and other information listed in the RADIUS Clients section Now youre ready to configure the network policy which will authenticate users in the specific active directory groups and grant them access. Policies item in the left list and right click on Network Policies and click NEW. You must enter a name for the policy, in this case were going to use Network Engineers Cisco LEVEL 1. The Treasures Of Montezuma 3 Free. After you have provided a policy name you must than configure the conditions which are required to match in order to successfully authenticate. You will need to create two conditions Configure a User Group to match the Network Engineers security group and the Client Friendly Name to match ND which denotes the device authenticating has a friendly name starting with NDOnce youve successfully added these conditions you should see the following Click next and youll be prompted to specify the access permission, leave this as the default Access Granted and click next. Cisco only supports the Unencrypted authentication PAP, SPAP methods. Uncheck everything and check Unencrypted authentication PAP, SPAP as shown below and click next After configuring the Authentication Methods you will be prompted to configure the Constraits, you can skip this section and just click next. When prompted to configure settings, remove the Framed Protocol and edit the Service Type and set it to Login which is under Others as shown below Next you will need to add a Vendor Specific Attribute by clicking on Vendor Specific under the left side settings and clicking the Add button. Scroll down the list and select Cisco AV Pair and click add. You will be prompted to add the Attribute Information, here you will click Add and set the attribute value as shell priv lvl1. This specifies which privilege level is returned to the authenticating userdevice after successful authentication. For Network Engineers this would be shell priv lvl1. Network Support Technicians would use shell priv lvl1. When added successfully you should see the following After you click next you will be presented a summary of the new network policy that you just created as shown below Click finish and youre ready co configure the Cisco Routers and Switches to authenticate to the NPS Radius Server. Please note that you will need to create another policy for the Network Support Technicians and any other privilege levels you wish to use. Cisco IOS AAA Configuration. The very first thing we need to do prior to configuring AAA is to setup a local user account so that when the RADIUS server has failed, you have the ability to still log into the device. This is done using the username command as demonstrated below R1 con. Press RETURN to get started. R1config terminal. Enter configuration commands, one per line. End with CNTLZ. R1configusername NORAD priv 1. Now we can enable AAA new model and configure the radius server group and default authentication list as demonstrated below R1configusername NORAD priv 1. R1configaaa group server radius NPSRADIUSSERVERS. R1config sg radiusserver private 1. CISCO. R1configaaa authentication login default group NPSRADIUSSERVERS local. R1configaaa authorization exec default group NPSRADIUSSERVERS local if authenticated. R1configaaa authorization console. INFO Users will ONLY authenticate to the RADIUS servers if the RADIUS server is alive when defining the default aaa authentication list using group NPSRADIUSSERVERS followed by local. If you are attempting to log into the device using a local account and the Radius servers are accessable than it will reject the authentication unless the local account used to log in also exist in Active Directory and are members of the Network Engineers or Network Support Technicians security group. And thats it for the basic Cisco IOS AAA config. You can however get into some more advanced configurations by using AAA list and applying a radius authentication list to the VTY lines and local authentication only to the console line. Verification. Now for the fun part, verification.
