Specifications

1234:4ef0::19:32ff:fe00:124

One may use the usual decimal notation of IPv4 for the last 4 bytes:

1234:4ef0::19:32ff:254.0.1.36

Radius

The passwords for HTTP, telnet, and serial console (depending on the model) can be
stored locally and / or authenticated via RADIUS. The RADIUS configuration supports a
primary server and a backup server. If the primary server does respond, the RADIUS re-
quest is sent to the backup server. If the local password and RADIUS are enabled at the
same time, the system is first checking locally, and then in the event of a failure the
RADIUS servers are contacted.

RADIUS attributes

The following RADIUS attributes are evaluated by the client:

Session-Timeout

: This attribute specifies (in seconds) how long an accepted RADIUS

request is valid. After this time has elapsed, the RADIUS server must be prompted
again. If this attribute is not returned, the default timeout entry from the configuration is
used instead.

Filter-Id

: If the value "admin" is set for this attribute, then an admin rights are assigned

for the login, otherwise only user access.

Service-Type

: This is an alternative to Filter-Id. A service type of "6" or "7" means ad-

min rights for the HTTP login, otherwise only limited user access.

HTTP Login

The HTTP login takes place via Basic Authentication. This means that it is the respons-
ibility of the web server, how long the login credentials are temporarily stored there. The
RADIUS parameter "Session-Timeout" therefore does not determine when the user has
to login again, but at what intervals the RADIUS servers are asked again.

4.6

SNMP

SNMP can be used for status information via UDP (port 161). Supported SNMP com-
mands are:

·

GET

·

GETNEXT

·

GETBULK

·

SET

To query via SNMP you need a Network Management System, such as HP OpenView,
OpenNMS, Nagios etc., or the simple command line tools of NET-SNMP software. The
device supports SNMP protocols v1, v2c and v3. If traps are enabled in the configuration,
