Managing the Switch
Configuring Notifications
Since the target parameters name is used to point to a number of objects used for notifications,
configure the target parameter name entry first. You can then configure the target address, filter profiles
and filters, and any necessary notification tags.

Authenticating Users

ExtremeWare XOS provides two methods to authenticate users who login to the switch:

• RADIUS client

• TACACS+

NOTE
You cannot configure RADIUS and TACACS+ at the same time.
RADIUS Client
Remote Authentication Dial In User Service (RADIUS, RFC 2138) is a mechanism for authenticating and
centrally administrating access to network nodes. The ExtremeWare XOS RADIUS client
implementation allows authentication for Telnet or console access to the switch.
TACACS+
Terminal Access Controller Access Control System Plus (TACACS+) is a mechanism for providing
authentication, authorization, and accounting on a centralized server, similar in function to the RADIUS
client. The ExtremeWare XOS version of TACACS+ is used to authenticate prospective users who are
attempting to administer the switch. TACACS+ is used to communicate between the switch and an
authentication database.

Configuring RADIUS Client and TACACS+

For detailed information about configuring a RADIUS client or TACACS+, see Chapter 9.

Using the Simple Network Time Protocol

ExtremeWare XOS supports the client portion of the Simple Network Time Protocol (SNTP) Version 3
based on RFC1769. SNTP can be used by the switch to update and synchronize its internal clock from a
Network Time Protocol (NTP) server. When enabled, the switch sends out a periodic query to the
indicated NTP server, or the switch listens to broadcast NTP updates. In addition, the switch supports
the configured setting for Greenwich Mean time (GMT) offset and the use of Daylight Saving Time.
These features have been tested for year 2000 compliance.
