Fix Recommendation

Configure the Arista network device to use an authentication server.

Step 1: Configure the Arista network device to use RADIUS server using the following commands:

switch#config
switch(config)#radius-server host 192.168.10.101 key 7 106D1A182224E12AZ
aaa group server radius RADIUS_1
server 192.168.10.101

Step 2: Configure all network connections associated with device management to use an authentication server for login authentication.

switch(config)#aaa authentication login default group radius local
aaa authentication login console group radius local
aaa authentication dot1x default group radius
aaa authentication policy on-success log
aaa authentication policy on-failure log
aaa authorization console
aaa authorization commands all default local
aaa accounting exec default start-stop group radius logging
aaa accounting system default start-stop group radius logging
aaa accounting commands all default start-stop logging group radius
switch(config)#exit

Check Contents

Verify the Arista network device is configured to use an authentication server as primary source for authentication.

Verify the Arista network device configuration for RADIUS server IP, aaa group server, and defined encryption key using the following example command:

switch#show running-config |section radius
radius-server host 192.168.10.101 key 7 106D1A182224E12AZ
!
aaa group server radius RADIUS_1
server 192.168.10.101
!
switch#show running-config | section aaa
aaa authentication login default group radius local
aaa authentication login console group radius local
aaa authentication dot1x default group radius
aaa authentication policy on-success log
aaa authentication policy on-failure log
aaa authorization console
aaa authorization commands all default local
aaa accounting exec default start-stop group radius logging
aaa accounting system default start-stop group radius logging
aaa accounting commands all default start-stop logging group radius

If the Arista network device is not configured to use an authentication server to authenticate users prior to granting administrative access, this is a finding.
