How to change request attribute based on NAS IP address

[Mehdi Ravanbakhsh]

Hi All

i use Cisco and mikrotik as Access server in my network  and i need to
limit user access by MAC address.

in this case i can use Calling-Station-Id , it works for mikrotik  :
AUTH Detail

        Packet-Type = Access-Request
	Service-Type = Framed-User
	Framed-Protocol = PPP
	NAS-Port = 11062419
	NAS-Port-Type = Ethernet
	User-Name = "7622240489"
	Calling-Station-Id = "90:F6:52:D5:74:96"
	Called-Station-Id = "EHO-L"
	NAS-Port-Id = "902- ADSL-EMAM-HOSIEN"
	NAS-Identifier = "2800gs-langha"
	NAS-IP-Address = 10.185.3.5
	SQL-User-Name = "7622240489"


But not work for Cisco :

        Packet-Type = Access-Request
	Cisco-AVPair = "client-mac-address=9094.e483.390b"
	Framed-Protocol = PPP
	User-Name = "5858222251"
	NAS-Port-Type = Ethernet
	NAS-Port = 13145502
	NAS-Port-Id = "0/0/2/352"
	Service-Type = Framed-User
	NAS-IP-Address = 85.185.83.242
	Acct-Session-Id = "00C8959E"
	NAS-Identifier = "BOJNOORD_7204_1"
	SQL-User-Name = "5858222251"


So how i can  Set calling station ID to MAC addreess for cisco NAS ?


Best regards.
