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 an MPLS L3VPN instance for the scheme
The VPN instance specified for an HWTACACS scheme applies to all servers in that scheme. If a
VPN instance is also configured for an individual HWTACACS server, the VPN instance specified for
the HWTACACS scheme does not take effect on that server.
To specify a VPN instance for an HWTACACS scheme:
Step
1. Enter system view.
2. Enter HWTACACS scheme
view.
3. Specify a VPN instance 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
