By default, the local AAA scheme is
applied. If you specify to apply the

HWTACACS scheme, you need to
perform the following configuration
as well:

configuration on the switch.
(Refer to the AAA part for more.)

password accordingly on the
AAA server. (Refer to the user

Note that:
If you configure to authenticate the users in the scheme mode, the command level available to the users
logging in to the switch depends on the user level defined in the AAA scheme.
z When the AAA scheme is local, the user level depends on the service-type { ftp | lan-access |
{ ssh | telnet | terminal }* [ level level ] } command.
z When the AAA scheme is RADIUS or HWTACACS, you need to specify the user level of a user on
the corresponding RADIUS or HWTACACS server.
