What is Switch Management Login? 77
■ The RADIUS server in your network is operational.
■ If the RADIUS server fails or is unavailable, client devices will be unable
to access the network.
■ Network Login is not supported on ports configured to operate as
members of an aggregated link.
■ Some client devices that are connected to the Switch port may not
support the authentication service, for example printers. You should
configure the Switch port to operate in No Security mode then switch
back to Static mode, so that network traffic that does not match the
MAC address for the client device is filtered.
■ You should enable Network Login on all edge Switch ports. Failure to
enable authentication on a single port could compromise the security
of the entire network.
What is Switch
Management
Login?
If you intend to manage the Switch using the Web interface or the
Command Line Interface, you need to log in with a valid user name and
password.
For further information on managing the Switch, see the “Setting Up For

The user name and password information can be stored in either:
■ a RADIUS server (recommended)
If you enable RADIUS as the authentication mode of Switch
Management Login, the user name and password information is
stored in a database on a RADIUS server in your network. Subsequent
log in attempts to the Switch are remotely authenticated by the
RADIUS server.
or
■ the local Switch database (default)
If you enable Local as the authentication mode of Switch
Management Login, the user name and password information is
stored in the local database on the Switch. Subsequent login attempts
to the Switch are authenticated by the local database.

Authentication
Day-to-day network maintenance can become a substantial overhead.
