Specifying the HWTACACS authorization servers
You can specify one primary authorization server and a maximum of 16 secondary authorization
servers for an HWTACACS scheme. When the primary server is not available, the device searches
for the secondary servers in the order they are configured. The first secondary server in active state
is used for communication.
If redundancy is not required, specify only the primary server. An HWTACACS server can function as
the primary authorization server of one scheme and as the secondary authorization server of another
scheme at the same time.
To specify HWTACACS authorization servers for an HWTACACS scheme:
Step
1. Enter system view.
2. Enter HWTACACS
scheme view.
3. Specify HWTACACS
authorization servers.
Specifying the HWTACACS accounting servers
You can specify one primary accounting server and a maximum of 16 secondary accounting servers
for an HWTACACS scheme. When the primary server is not available, the device searches for the
secondary servers in the order they are configured. The first secondary server in active state is used
for communication.
If redundancy is not required, specify only the primary server. An HWTACACS server can function as
the primary accounting server of one scheme and as the secondary accounting server of another
scheme at the same time.
The device sends HWTACACS stop-accounting requests when it receives connection teardown
requests from hosts or connection teardown commands from an administrator. However, the device
might fail to receive a response for a stop-accounting request in a single transmission. Enable the
device to buffer HWTACACS stop-accounting requests that have not received responses from the
accounting server. The device will resend the requests until responses are received.
To limit the transmission times, set a maximum number of attempts that can be made for transmitting
individual HWTACACS stop-accounting requests. When the maximum attempts are made for a
request, the device discards the buffered request.
HWTACACS does not support accounting for FTP, SFTP, and SCP users.
To specify HWTACACS accounting servers for an HWTACACS scheme:
Command

hwtacacs scheme
hwtacacs-scheme-name
•
Specify the primary HWTACACS
authorization server:
primary authorization
{ host-name | ipv4-address | ipv6
ipv6-address } [ port-number | key
{ cipher | simple } string |
single-connection |
vpn-instance
vpn-instance-name ] *
•
Specify a secondary HWTACACS
authorization server:

By default, no authorization
servers are specified.
Two HWTACACS authorization
servers in a scheme, primary or
secondary, cannot have the same
combination of host name, IP
address, port number, and VPN
instance.
