Abstract

This document provides examples on configuring RADIUS & TACACS+ on the ERS 1600, 8300, 8600, 2500, 4500, 5500 and ES 460/470. This document covers some of the more popular Radius & TACACS+ commands and attributes how to configure server and client side. It gives also various examples with different users and details log files on client and server side. Finally some sniffer traces show how protocols exchange data between server and client.

Authentication, Authorization and Accounting (AAA) for ERS and ES

Technical Configuration Guide

November 2010

1. Overview

Access control is the way you control who is allowed access to the network server and what services they are allowed to use once they have access. Authentication, authorization, and accounting (AAA) network security services provide the primary framework through which you set up access control on your network device or access server.

Network professionals have always been challenged with having many individuals manage multiple network devices with a single account. When problems occur it is nearly impossible to trace back accountability and identify what changes were made by whom. RADIUS was designed to combat the authentication and accounting (logging tied to user) problem; however, authorization (what an authenticated user was allowed to do) controls were still missing. TACACS+ (latest implementation of TACACS) has the ability to do authentication, authorization and accounting.

2. RADIUS

Remote Access Dial-In User Services (RADIUS) is a distributed client/server system that assists in securing networks against unauthorized access, allowing a number of communication servers and clients to authenticate user identities through a central database. The database within the RADIUS server stores information about clients, users, passwords, and access privileges, protected with a shared secret.

RADIUS is a fully open and standard protocol defined by RFCs (authentication [RFC 2865] and accounting [RFC 2866]). RADIUS protocol is an AAA protocol using IP framing with UDP port 1812 for authentication and port 1813 for accounting.

2.1 Feature Operation

A RADIUS application has two components:

 RADIUS server : A computer equipped with RADIUS server software (for example, a UNIX*

workstation) that is located at a central office or campus. It has authentication and access information in a form that is compatible with the client. Typically, the database in the RADIUS server stores client information, user information, password, and access privileges, including the use of shared secret. A network can have at minimum one server for both authentication and accounting, or one server for each service.

 RADIUS client : A switch, router, or a remote access device equipped with RADIUS client

software that sends the authentication request to the RADIUS server upon a user attempting to login via the RADIUS client. The client is the network access point between the remote users and the server.

The RADIUS process includes:

 RADIUS authentication, which you can use to identify remote users before you give them access

to a central network site.

 RADIUS accounting, which enables data collection on the server during a remote user’s dial-in

session with the client.

802.1x (EAP), if enabled, has a mandatory requirement to authenticate users by Radius. Hence, Layer two switches supporting 802.1x (EAP) support RADIUS authentication.

2.1.1 RADIUS Authentication

With RADIUS authentication, a remote RADIUS client can authenticate users attempting to log in. The RADIUS server also provides access authority. RADIUS assists network security and authorization by managing a database of users. The switch can use the database to verify user names and passwords, as well as information about the type of access priority available to the user.

When the RADIUS client sends an authentication request, if the RADIUS server requires additional information, such as a SecurID number, it sends a challenge-response. Along with the challengeresponse, a reply-message attribute is sent. The reply-message is a text string, such as "Please enter the next number on your SecurID card". The maximum length of each reply-message attribute is 253 characters (as defined by the RFC). If you have multiple instances of reply-message attributes that together form a large message which can be displayed to the user, the maximum total length is 2000 characters.

2.1.2 RADIUS Accounting

RADIUS accounting logs all of the activity of each remote user in a session on the centralized RADIUS accounting server. Session IDs for each RADIUS account are generated as 12-character strings. The first four characters in the string form a random number in hexadecimal format. The last eight characters in the string indicate, in hexadecimal format, the number of user sessions started since reboot.

The Network Access Server (NAS) IP address for a session is the address of the switch interface to which the remote session is connected over the network. For a console session, modem session, and sessions running on debug ports, this value is set to 0.0.0.0 (as is done with RADIUS authentication).

2.1.3 RADIUS Accounting for 802.1x (EAP)

Ethernet Routing Switch 1600, 8600, 8300, 5500 and 4500 supports accounting for 802.1x ( EAP) sessions using RADIUS accounting protocol. A user session is defined as the interval between the instance at which a user is successfully authenticated (port moves to authorized state) and the instance at which the port moves out of the authorized state.

2.1.4 RADIUS Accounting for CLI Commands

RADIUS accounting will keep track of user, session duration, number of octects and packets (in and out). This feature allows you to keep track of all CLI commands typed by user during session.

2.1.5 RADIUS User Access Profile

As a network administrator, you can override a user’s access to specific CLI commands by configuring the RADIUS server for user authentication. You must still give access based on the existing six access levels in the ERS 8600, but you can customize user access by permitting and preventing access to specific CLI commands.

2.1.6 RADIUS SNMP Accounting

RADIUS accounting will record the duration of the SNMP version 1, 2 or 3 session and the number of packets/octets sent and received during the SNMP session.

The source IP address sent by the switch (Layer 2 operation) is always the Management IP address configured on the switch when sending a RADIUS client authentication request.

There is no way to change source RADIUS IP address. When the switch is configured in routed mode, it uses interface IP address where frame is sent. Hence, if you have multiple IP interfaces facing the core network where a RADIUS request could be sent, you will have to configure the RADIUS server with each IP address.



With the ES 460/470 and ERS 2500, 4500, 5500 switches, you can configure two RADIUS servers, a primary server and a secondary server. If all servers are not reachable (no answers) then local authentication is done if Password Fallback feature is enabled. You get the following message at console:

no response from RADIUS servers

2.4.1 ES 460/470 Series and ERS 2500, 4500, 5500

ACLI or JDM (Java Device Manager) can be used to configure the switch. For simplicity and readability, we will document command line interface commands assuming the RADIUS server IP address is

10.10.50.40, and the client shared secret is ―Dda‖ for telnet access authentication.

With the ERS 1600, 8300, and 8600, you can change the RADIUS source IP address by using the following command :



With the ERS 1600, 8300, and 8600, you can configure up to ten RADIUS servers (each server is assigned a priority and is contacted in that order). If all servers are not reachable (no answer) then local authentication is done and you will receive the following message:

No reply from RADIUS server "10.10.50.40(1812)"All RADIUS servers are

unreachable.

Please note that there is no Administrative RADIUS accounting for ES460/470 Series and ERS 2500, 4500, 5500.

RADIUS accounting is only available for 802.1x (EAP) users.

2.5 RADIUS Server & Client Log Files

In this section, we will demonstrate RADIUS server and client logging on the switch. We will demonstrate a client logging onto a switch, issuing several commands and checking if they are allowed or not based on authentication rights.



Please note that the client-IP-Address is equal to NAS-IP-Address which is not correct. The client-IP-Address is the station where telnet has been issued, which is 10.10.50.10. The reason is the switch does not provide a Client-IP-address field (see sniffer trace). Application artificially copy field.
