Parameters
host-name: Specifies the host name of a secondary HWTACACS accounting server, a
case-insensitive string of 1 to 253 characters.
ipv4-address: Specifies the IPv4 address of a secondary HWTACACS accounting server.
ipv6 ipv6-address: Specifies the IPv6 address of a secondary HWTACACS accounting server.
port-number: Specifies the service port number of the secondary HWTACACS accounting 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
accounting 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 accounting server use the same
TCP connection to exchange all accounting packets for all users. If you do not specify this keyword,
the device establishes a new TCP connection each time it exchanges accounting packets with the
secondary accounting server for a user.
vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance to which the secondary
HWTACACS accounting 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 the secondary HWTACACS accounting
server are the same as those configured on the server.
An HWTACACS scheme supports a maximum of 16 secondary HWTACACS accounting 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 accounting command, the command
removes all secondary accounting servers.
Two accounting 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.
You can remove an accounting server only when it is not used for user accounting. Removing an
accounting server affects only accounting processes that occur after the remove operation.
Examples
# In HWTACACS scheme hwt1, specify a secondary accounting server with IP address
10.163.155.12, TCP port number 49, and plaintext shared key 123456TESTacct&!.
