This section describes how to set parameters for a FW to communicate with an HWTACACS server.
If an HWTACACS server is deployed to implement server authentication on users, a FW sends the user names and passwords to the HWTACACS server. To ensure normal communication between the FW and the HWTACACS server, set the parameters on the FW for communication with the HWTACACS server.
To use the HWTACACS server to assign IP addresses for PPPoE dial-up users, you must specify the HWTACACS server as the authorization server.

The parameter settings on the FW must be consistent with those on the HWTACACS server.
Parameter |
Description |
|---|---|
Name |
Name of an HWTACACS server |
Shared Key |
Shared key for the communication between a FW and an HWTACACS server The FW and HWTACACS server use this key to encrypt packets. |
Primary Authentication Server IP Address/Port |
IP address and port of the primary HWTACACS server that provides authentication services Normally, an HWTACACS server provides authentication services on port 49. |
Secondary Authentication Server IP Address/Port |
IP address and port of the secondary HWTACACS server that provides authentication services The FW preferentially uses the active HWTACACS server. If the primary HWTACACS server is unreachable, the FW uses the secondary HWTACACS server. |
Third Authentication Server IP Address/Port |
IP address and port of the third HWTACACS server that provides authentication services If the secondary authentication server is unreachable, the third authentication server is used. |
Primary Authorization Server IP Address/Port |
IP address and port of the primary HWTACACS server that provides authorization services Normally, an HWTACACS server provides authorization services on port 49 |
Secondary Authorization Server IP Address/Port |
IP address and port of the secondary HWTACACS server that provides authorization services The FW preferentially uses the active HWTACACS server. If the primary HWTACACS server is unreachable, the FW uses the secondary HWTACACS server. |
Third Authorization Server IP Address/Port |
IP address and port of the third HWTACACS server that provides authorization services If the secondary authorization server is unreachable, the third authorization server is used. |
Primary Accounting Server IP Address/Port |
IP address and port of the primary HWTACACS server that provides accounting services Normally, an HWTACACS server provides accounting services on port 49. |
Secondary Accounting Server IP Address/Port |
IP address and port of the secondary HWTACACS server that provides accounting services The FW preferentially uses the active HWTACACS server. If the primary HWTACACS server is unreachable, the FW uses the secondary HWTACACS server. |
Third Accounting Server IP Address/Port |
IP address and port of the third HWTACACS server that provides accounting services If the secondary accounting server is unreachable, the third accounting server is used. |
Advanced Settings |
|
Source IP Address |
IP address used by a FW to communicate with an HWTACACS server If this parameter is not specified, the FW uses the IP address of the outbound interface to communicate with the HWTACACS server. |
Unit |
Traffic unit an HWTACACS server uses for charging
|
Reply Timeout |
Duration for which a FW waits for reply packets from an HWTACACS server To check whether an HWTACACS server fails, the FW periodically sends request packets to the HWTACACS server. If the FW does not receive any reply packet within the specified timeout period, it retransmits the request packet. |
Quiet Time |
Duration that the HWTACACS server waits to restore the active state it has recovered, in minutes |
