Authentication

Contents

This scenario shows how to set up AAA authentication for login/Telnet using different AAA methods.

Local Method

Description

An AAA list with the local AAA method is created and assigned to the login system’s authentication. The device then starts a Telnet session with itself to check that access is granted when the correct username and password are used.

Scenario

Step 1: Set the following configuration in DUT0:

set service telnet
set system aaa list list1 method 1 local
set system login aaa authentication list1
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 2: Init a Telnet connection from DUT0 to IP address 127.0.0.1 :

admin@DUT0$ telnet 127.0.0.1

Show output

Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.

Radius Method

Description

A RADIUS server is added to a RADIUS group, which is added to an AAA list. This list is assigned to the login system’s authentication. The device then starts a Telnet session with itself to check that access is granted when the correct username and password are used.

Scenario

Step 1: Set the following configuration in DUT0:

set interfaces ethernet eth0 address 10.215.168.64/24
set service telnet
set system aaa group radius radgroup1 server serv1
set system aaa list list1 method 1 group radius radgroup1
set system aaa server radius serv1 address 10.215.168.1
set system aaa server radius serv1 encrypted-key U2FsdGVkX18qB62H77B6N32URhNLr+54VlPGvA85RJR2mum0fNz80h5DUwv8tQNh5jlSaV6K00yPZeTg/wG1TQ==
set system login aaa authentication list1
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 2: Ping IP address 10.215.168.1 from DUT0:

admin@DUT0$ ping 10.215.168.1 count 1 size 56 timeout 1

Show output

PING 10.215.168.1 (10.215.168.1) 56(84) bytes of data.
64 bytes from 10.215.168.1: icmp_seq=1 ttl=64 time=0.227 ms

1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.227/0.227/0.227/0.000 ms

Step 3: Init a Telnet connection from DUT0 to IP address 127.0.0.1 :

admin@DUT0$ telnet 127.0.0.1

Show output

Trying 127.0.0.1...
Connected to 127.0.0.1.

Tacacs Method

Description

A TACACS+ server is added to a TACACS+ group, which is added to an AAA list. This list is assigned to the login system’s authentication. The device then starts a Telnet session with itself to check that access is granted when the correct username and password are used.

Scenario

Step 1: Set the following configuration in DUT0:

set interfaces ethernet eth0 address 10.215.168.64/24
set service telnet
set system aaa group tacacs tacgroup1 server serv1
set system aaa list list1 method 1 group tacacs tacgroup1
set system aaa server tacacs serv1 address 10.215.168.1
set system aaa server tacacs serv1 encrypted-key U2FsdGVkX1+IGWVQ/PUxC3HE6X4Id5lzh2BKBLF2X7c=
set system login aaa authentication list1
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 2: Ping IP address 10.215.168.1 from DUT0:
