Supported RADIUS attributes
The HP 10GbE switch 802.1x Authenticator relies on external RADIUS servers for authentication with
EAP. The following table lists the RADIUS attributes that are supported as part of RADIUS-EAP
authentication based on the guidelines specified in Annex D of the 802.1x standard and RFC 3580.
Table 9 EAP support for RADIUS attributes
# Attribute Attribute Value A-R A-A A-C A-R
1 User-Name The value of the Type-Data field from the
supplicant’s EAP-Response/Identity message.
If the Identity is unknown (i.e. Type-Data field
is zero bytes in length), this attribute will have
the same value as the Calling-Station-Id.
1 0-1 0 0
4 NAS-IP-Address IP address of the authenticator used for
RADIUS communication.
1 0 0 0
5 NAS-Port Port number of the authenticator port to which
the supplicant is attached.
1 0 0 0
24 State Server-specific value. This is sent unmodified
back to the server in an Access-Request that is
in response to an Access-Challenge.
0-1 0-1 0-1 0
30 Called-Station-ID The MAC address of the authenticator
encoded as an ASCII string in canonical
format, e.g. 000D5622E3 9F.
1 0 0 0
31 Calling-Station-ID The MAC address of the supplicant encoded
as an ASCII string in canonical format, e.g.
00034B436206.
1 0 0 0
79 EAP-Message Encapsulated EAP packets from the supplicant
to the authentication server (Radius) and vice-
versa. The authenticator relays the decoded
packet to both devices.
1+ 1+ 1+ 1+
80 Message-Authenticator Always present whenever an EAP-Message
attribute is also included. Used to integrity-
protect a packet.

87 NAS-Port-ID Name assigned to the authenticator port, e.g.
Server1_Port3
