Fix Recommendation

Step 1: Configure the Cisco switch to use at least two authentication servers as shown in the example below:

SW4(config)#radius host 10.1.48.2 key xxxxxx
SW4(config)#radius host 10.1.48.3 key xxxxxx

Step 2: Configure the authentication order to use the authentication servers as the primary source for authentication as shown in the example below:

SW4(config)#aaa authentication login CONSOLE group radius local

SW4(config)#aaa authentication login LOGIN_AUTHENTICATION group radius local

Step 3: Configure all network connections associated with device management to use the authentication servers for login authentication:

SW4(config)#line vty 0 1
SW4(config-line)#login authentication LOGIN_AUTHENTICATION
SW4(config-line)#exit
SW4(config)#line con 0
SW4(config-line)#login authentication CONSOLE
SW4(config-line)#exit
SW4(config)#ip http authentication aaa login-authentication LOGIN_AUTHENTICATION

Review the Cisco switch configuration to verify the device is configured to use at least two authentication servers as the primary source for authentication as shown in the example below:

aaa new-model
!
aaa authentication login CONSOLE group radius local
aaa authentication login LOGIN_AUTHENTICATION group radius local
…
…
…
ip http authentication aaa login-authentication LOGIN_AUTHENTICATION
ip http secure-server
…
…
…
radius-server host x.x.x.x auth-port 1812 acct-port 1813 key xxxxxxx
radius-server host x.x.x.x auth-port 1812 acct-port 1813 key xxxxxxx
…
…
…
line con 0
exec-timeout 5 0
login authentication CONSOLE
line vty 0 1
exec-timeout 5 0
login authentication LOGIN_AUTHENTICATION

If the Cisco switch is not configured to use at least two authentication servers to authenticate users prior to granting administrative access, this is a finding.
