authentication request to the first TACACS host in the server group. If no response comes from the server host, the
Switch will send an authentication request to the second TACACS host in the server group and so on, until the list is
exhausted. At that point, the Switch will restart the same sequence with the following protocol listed, XTACACS. If no
authentication takes place using the XTACACS list, the local account database set in the Switch is used to
authenticate the user. When the local method is used, the privilege level will be dependent on the local account
privilege configured on the Switch.
Successful login using any of these techniques will give the user a "User" privilege only. If the user wishes to upgrade
his or her status to the administrator level, the user must use the Enable Admin window, in which the user must enter
a previously configured password, set by the administrator.
