The effectiveness of security depends on correctly using your
server application. For this reason, HP recommends that you
thoroughly test all configurations used in your network.
TACACS-aware HP switches include the capability of configuring multiple
backup servers. HP recommends that you use a server
application that supports a redundant backup installation. This allows you to
configure the switch to use a backup server if it loses access to the
first-choice server.

General Authentication Setup Procedure
It is important to test the service before fully implementing it.
Depending on the process and parameter settings you use to set up and test
authentication in your network, you could accidentally lock all
users, including yourself, out of access to a switch. While recovery is simple,
it may pose an inconvenience that can be avoided.To prevent an unintentional
lockout on a Switch 4108GL, use a procedure that configures and tests
protection for one access type (for example, Telnet access), while
keeping the other access type (console, in this case) open in case the Telnet
access fails due to a configuration problem. The following procedure outlines
a general setup procedure.

If a complete access lockout occurs on the switch as a result of a
configuration, see "Troubleshooting Operation" on page “Trouble-
shooting Operation” on page 18-13 for recovery methods.
1.
Familiarize yourself with the requirements for configuring your
server application to respond to requests from a Switch
4108GL. (Refer to the documentation provided with the server
software.) This includes knowing whether you need to configure an
encryption key. (See “Using the Encryption Key” on page 26.)
