WLC Admin Access by TACAS+ Server

In this post we will learn how to provide or control WLC management user’s access via TACAS+ server.

We will create 3 users:

User1: Full Admin rights on WLC – sandeeprw
User2: Read-Only rights to WLC (Only allow one tab”WLAN” as admin access) – sandeepro
User3: Lobby user to create Guest Accounts – sandeeplobby

Parameters:

ACS Server: 192.168.205.5
WLC: 192.168.112.10
Shared Secret: Test12345

Read/Write User: sandeeprw, Password: sandeeprw
Read/Only User: sandeepro, Password: sandeepro
Lobby User: sandeeplobby, Password: sandeeplobby

Steps:

1. Add ACS server to WLC as TACAS+ server
2. Add WLC as AAA client to ACS.
3. Create Identity Groups.
4. Create Users and assign to respective Identity Groups
5. Assign shell profiles to Users
6. Configure Access Policies for specific Users
7. Assign the Priority order for management access.
8. Verification

So let’s start with configuration:

Add ACS server to WLC as TACAS+ server

Go to WLC GUI, click Security > AAA > TACAS+ > Authentication. Enter the parameters specific to the server. Also put Accounting& Authorization server info as well.

Add WLC as AAA client to ACS

Login to ACS and then go to Network Resources > Network Devices and AAA Clients

Must select TACAS+ check box and put the same shared secret as we did while adding ACS to WLC.

Create Identity Groups

Create Identity groups for different users.

These are the Groups:

Admin-Lobby
Admin-RO
Admin-RW

Create Users and assign to respective Identity Groups

Assign shell profiles to Users

Here we will create shell profile and assign the custom attributes to users.

Admin Users: role1 as ALL
Read-Only User: role1 as WLAN
Lobby Users: role1 as MONITOR

Configure Access Policies for specific Users

Create Authorization rules under default Network Access:

It will look like this:

Assign the Priority order for management access

Authentication Oder for management users on the WLC.

Security > Priority Order > Management User.

Verification

To verify each account, we must login with different users and check it.

Verification Logs from ACS about users attempts:

That’s all 🙂

In the next post we will learn the AAA override /Dynamic VLAN Assignment feature.
