Parameters
host-name
: Specifies the host name of a secondary HWTACACS authentication server, a
case-insensitive string of 1 to 253 characters.
ipv4-address : Specifies the IPv4 address of a secondary HWTACACS authentication server.
ipv6 ipv6-address
: Specifies the IPv6 address of a secondary HWTACACS authentication
server.
port-number
: Specifies the service port number of the secondary HWTACACS authentication
server. The value range for the TCP port number is 1 to 65535. The default setting is 49.
key
: Specifies the shared key for secure communication with the secondary HWTACACS
authentication server.
cipher
: Specifies the key in encrypted form.
simple
: Specifies the key in plaintext form. For security purposes, the key specified in plaintext
form will be stored in encrypted form.
string
: Specifies the key. This argument is case sensitive. In non-FIPS mode, the encrypted form
of the key is a string of 1 to 373 characters. The plaintext form of the key is a string of 1 to 255
characters. In FIPS mode, the encrypted form of the key is a string of 15 to 373 characters. The
plaintext form of the key is a string of 15 to 255 characters. The plaintext string must contain digits,
uppercase letters, lowercase letters, and special characters.
single-connection
: The device and the secondary HWTACACS authentication server use the
same TCP connection to exchange all authentication packets for all users. If you do not specify this
keyword, the device establishes a new TCP connection each time it exchanges authentication
packets with the secondary authentication server for a user.
vpn-instance vpn-instance-name
: Specifies an MPLS L3VPN instance to which the
secondary HWTACACS authentication server belongs. The vpn-instance-name argument is a
case-sensitive string of 1 to 31 characters. If the server is on the public network, do not specify this
option.
Usage guidelines
Make sure the port number and shared key settings of each secondary HWTACACS authentication
server are the same as those configured on the corresponding server.
An HWTACACS scheme supports a maximum of 16 secondary HWTACACS authentication servers.
If the primary server fails, the device tries to communicate with a secondary server in active state.
The device connects to the secondary servers in the order they are configured.
If you do not specify any parameters for the
undo secondary authentication
command, the
command removes all secondary authentication servers.
Two authentication servers specified for a scheme, primary or secondary, cannot have identical VPN
instance, host name, IP address, and port number settings.
As a best practice, specify the
single-connection
keyword to reduce TCP connections for
improving system performance if the HWTACACS server supports the single-connection method.
If the specified server resides on an MPLS L3VPN, specify the VPN instance by using the
vpn-instance vpn-instance-name option. The VPN instance specified by this command
takes precedence over the VPN instance specified for the HWTACACS scheme.
