Command accounting allows the HWTACACS server to record all commands executed by users,
regardless of command execution results. This function helps control and monitor user behaviors on the
device. If command accounting is enabled and command authorization is not enabled, every executed
command is recorded on the HWTACACS server. If both command accounting and command
authorization are enabled, only the authorized and executed commands are recorded on the
HWTACACS server.
Follow these guidelines when you configure the SSH server:
•
To make the command authorization or command accounting function take effect, apply an
HWTACACS scheme to the intended ISP domain. This scheme must specify the IP address of the
authorization server and other authorization parameters.
•
If the local authentication scheme is used, use the
authorization-attribute level
level command in
local user view to set the user privilege level on the device.
•
If a RADIUS or HWTACACS authentication scheme is used, set the user privilege level on the
RADIUS or HWTACACS server.
The SSH client authentication method is password in this configuration procedure. For more information
about SSH and publickey authentication, see
Security Configuration Guide.
