Using external radius with ise for guest authentication

[jan.nielsen]

Hi Everyone,

I am trying to migrate from NAC Guest Server to Cisco ISE Guest CWA on wireless, and can't figure out whether what i am trying is just unsupported or i just can't find out how to do this ?

I am attempting to authenticate my existing guest users, using a radius lookup towards my existing NAC Guest server, which has many hundred guest users with long account duration, which i really don't want to recreate on ISE, and send new passwords to all those users. Problem is i can't export the user list from NAC guest server with the password intact, and ISE can't import guest users with a set password.

Any ideas ?

Setup Proxy-RADIUS between the two?

Hi Jan,

I understand what problem you're going through. There is a way to export users from the NAC Guest server; however it does not help us to import the users information with existing password. Richard suggested you the right thing to setup ISE as a RADIUS proxy server that will proxy the requests from a Network Access Device (NAD) to a RADIUS server  NAC Guest Server (NGS).

Setting up ISE as radius  proxy server will work because NAC guest user does not support exporting user information with passwords

Step 1 Choose Administration > Network Resources > External RADIUS Servers.

The External RADIUS Servers page appears.

Step 2 Click Filter > Advanced Filter to perform your search. The Filter page appears.

Step 3 You must define whether the search should match any or all of the rules that you define on this page.

Step 4 Enter your search criteria based on the name or description of the RADIUS server, choose an operator, and enter the value.

Step 5 You can do the following:

•To add a filter condition, click the plus sign (+).

•To remove a filter condition, click the minus sign (-).

•To clear all filter conditions, click Clear Filter.

Step 6 Click Go to perform your search.

You can also save the filter criteria so that it can be used again. Click the Save icon to save the filter condition.
