Configuring authentication-method lists
4
Configuration considerations for authentication-
method lists
Consider the following before configuring authentication-method lists:
• For CLI access, you must configure authentication-method lists if you want the device to
authenticate access using local user accounts or a RADIUS server. Otherwise, the device will
authenticate using only the locally based password for the Super User privilege level.
• When no authentication-method list is configured specifically for Web management access,
the device performs authentication using the SNMP community strings:
• For read-only access, you can use the user name “get” and the password “public”. The
default read-only community string is “public”.
• There is no default read-write community string. Thus, by default, you cannot open a
read-write management session using the Web management interface. You first must
configure a read-write community string using the CLI. Then you can log on using “set” as
the user name and the read-write community string you configure as the password. Refer
to “Configuring TACACS and TACACS+ security” on page 82.
• If you configure an authentication-method list for Web management access and specify “local”
as the primary authentication method, users who attempt to access the device using the Web
management interface must supply a user name and password configured in one of the local
user accounts on the device. The user cannot access the device by entering “set” or “get” and
the corresponding SNMP community string.
• For devices that can be managed using IronView Network Manager, the default authentication
method (if no authentication-method list is configured for SNMP) is the CLI Super User level
password. If no Super User level password is configured, then access through IronView
Network Manager is not authenticated. To use local user accounts to authenticate access
through IronView Network Manager, configure an authentication-method list for SNMP access
and specify “local” as the primary authentication method.
Examples of authentication-method lists
The following example shows how to configure authentication-method lists for the Web
Management Interface, IronView Network Manager, and the Privileged EXEC and CONFIG levels of
the CLI. In this example, the primary authentication method for each is “local”. The device will
authenticate access attempts using the locally configured user names and passwords first.
To configure an authentication-method list for the Web Management Interface, enter a command
such as the following.
BigIron RX(config)# aaa authentication web-server default local
This command configures the device to use the local user accounts to authenticate access to the
device through the Web Management Interface. If the device does not have a user account that
matches the user name and password entered by the user, the user is not granted access.
To configure an authentication-method list for IronView Network Manager, enter a command such
as the following.
BigIron RX(config)# aaa authentication snmp-server default local
This command configures the device to use the local user accounts to authenticate access
attempts through any network management software, such as IronView Network Manager.
