Incorrect NAS-IP-Address attribute

[Morris, Andi]

Hi all,
Can somebody tell me where the NAS-IP-Address attribute is pulled from?

I have one particular switch that has a different IP address in this attribute to the actual switch's IP address, and therefore radius rejects the request as this IP address isn't a declared client. All my other switches are working fine so the radius server is fine in general. I'm just not sure whether this is set on the radius server, or the switch. I can't find it on either.

Here's a debug log snippet:
rad_recv: Access-Request packet from host 10.1.1.10 port 1812, id=9, length=159
        NAS-IP-Address = 10.1.1.12
        NAS-Port = 50024
        Cisco-NAS-Port = "FastEthernet0/24"
        NAS-Port-Type = Ethernet
        User-Name = "st12345678"
        Called-Station-Id = "00-0D-28-1A-36-98"
        Calling-Station-Id = "F0-DE-F1-D4-FB-D7"
        Service-Type = Framed-User
        Framed-MTU = 1500
        EAP-Message = 0x0200000f0173743230303235313330
        Message-Authenticator = 0x07b499ef56d777d5284f72c3ad2cc15a

Thanks in advance.
