Specifying the shared keys for secure HWTACACS communication
The HWTACACS client and server use the MD5 algorithm and shared keys to generate the
Authenticator value for packet authentication and user password encryption. The client and server
must use the same key for each type of communication.
Perform this task to configure shared keys for servers in an HWTACACS scheme. The keys take
effect on all servers for which a shared key is not individually configured.
To specify a shared key for secure HWTACACS communication:
Step
1. Enter system view.
2. Enter HWTACACS scheme
view.
3. Specify a shared key for
secure HWTACACS
authentication,
authorization, or accounting
communication.
Specifying a VPN for the scheme
The VPN specified for an HWTACACS scheme applies to all servers in that scheme. If a VPN is also
configured for an individual HWTACACS server, the VPN specified for the HWTACACS scheme
does not take effect on that server.
To specify a VPN for an HWTACACS scheme:
Step
1. Enter system view.
2. Enter HWTACACS scheme
view.
3. Specify a VPN for the
HWTACACS scheme.
Setting the username format and traffic statistics units
A username is typically in the userid@isp-name format, where the isp-name argument represents
the user's ISP domain name. By default, the ISP domain name is included in a username. If
HWTACACS servers do not recognize usernames that contain ISP domain names, you can
configure the device to send usernames without domain names to the servers.
If two or more ISP domains reference the same HWTACACS scheme, configure the HWTACACS
scheme to keep the ISP domain name in usernames for domain identification.
The device reports online user traffic statistics in accounting packets. The traffic measurement units
are configurable, but they must be the same as the traffic measurement units configured on the
HWTACACS accounting servers.
To set the username format and traffic statistics units for an HWTACACS scheme:
Step
1. Enter system view.
