Configuring local authentication as backup

It is useful to enable local authentication, so that the switch can take over authentication locally if the
RADIUS or LDAP servers fail to respond because of power outage or network problems.

1. Connect to the switch and log in using an account with admin permissions.
2. Enter the aaaConfig --authspec command to enable or disable RADIUS, LDAP, or TACACS+ with

local authentication as a backup authentication mechanism.

You must specify the type of service as one of RADIUS, LDAP, or TACACS+. Local is used for local
authentication if the user authentication fails on the authentication server.of enabling local
authentication as a backup for RADIUS.

switch:admin> aaaconfig --authspec "radius;local" -backup

Example for LDAP

switch:admin> aaaconfig --authspec "ldap;local" -backup

Example for TACACS+

switch:admin> aaaconfig --authspec "tacacs+;local" -backup

For details about the aaaConfig command refer to

Command options

on page 150.

When local authentication is enabled and the authentication servers fail to respond, you can log in to
the default switch accounts (admin and user) or any user-defined account. You must know the
passwords of these accounts.

When the aaaConfig command succeeds, the event log indicates that local database authentication
is disabled or enabled.
