General system requirements

To use TACACS+ authentication, you need the following:

A TACACS+ server application installed and configured on one or more servers or management stations in your network. There are several TACACS+ software packages available.
A switch configured for TACACS+ authentication, with access to one or more TACACS+ servers.

NOTE: The effectiveness of TACACS+ security depends on correctly using your TACACS+ server application. For this reason, HP recommends that you thoroughly test all TACACS+ configurations used in your network.

TACACS-aware HP switches include the capability of configuring multiple backup TACACS+ servers. HP recommends that you use a TACACS+ server application that supports a redundant backup installation. This allows you to configure the switch to use a backup TACACS+ server if it loses access to the first-choice TACACS+ server.

TACACS+ does not affect WebAgent access. See Controlling WebAgent access when using TACACS+ authentication
