Required TACACS+ server settings 
The following TACACS+ server settings must be configured on VC to enable TACACS+-based 
authentication: 
•  Enable or disable flag 
•  TACACS+ server IP address 
•  Server SSL port number—the default (well-known) value for TACACS+ authentication is 49. 
•  Shared secret server key—this is a plain text key that must be configured both on VC and on the server. 
Both keys should match. The length of the secret key can vary from 1 to 128 characters. 
•  Timeout—the time in seconds by which a server response must be received, before any retry for a new 
request is made. The valid range of values is from 1 to 65535 seconds. 
Setting up an IPv4-only TACACS+ server 
The following procedure provides an example of setting up a TACACS+ server on an external host running 
Linux. 
1.  Download and install the latest version of the open-source Cisco TACACS+ server from the shrubbery 
ftp site (ftp://ftp.shrubbery.net/pub/tac_plus). 
2.  Add the shared-secret key for VC, a list of users, their passwords and member groups (can be 
recursive), and the VCM roles to be authorized for each user or group in the server configuration file 
/etc/tac_plus.conf. For example: 
# set the secret key for client 
host = 10.10.10.113 { 
 key = tac!@123 <------- Secret-key for 10.10.10.113 
} 
# users accounts 
user = tacuser { 
 login = cleartext "password" 
 member = testgroup  <------- Member of group "testgroup" 
} 
# groups 
group = testgroup1 { 
 member = ALL_STAFF 
 service = hp-vc-mgmt {  <------- Service for 
role-authorization 
 autocmd = network <------- Authorize privilege "network" 
 autocmd = domain  <------- Authorize privilege "domain" 
 } 
} 
group = testgroup2 { 
 member = ALL_STAFF 
 service = hp-vc-mgmt {
