Remote authentication

Displaying the current authentication configuration
1. Connect to the switch and log in using an account with admin permissions.
2. Enter the aaaConfig
--show command.
If a configuration exists, its parameters are displayed. If the RADIUS, LDAP, or TACACS+ service
is not configured, only the parameter heading line is displayed. Parameters include:
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.
Example 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 this command see Table 17 on page 151.
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.
Position The order in which servers are contacted to provide service.
Server The server names or IPv4 or IPv6 addresses. IPv6 is not supported when using PEAP
authentication.
Port The server ports.
Secret The shared secrets.
Timeouts The length of time servers have to respond before the next server is contacted.
Authentication The type of authentication being used on servers.
