User configuration that we are using currently with freeradius is commented below.. we are not getting any errors with cisco devices that supports PPP. But, Cisco 887 Vag device doesnt support PPP protocol at 3g interfaces. The encapsulation protocol SLIP is supported with this device.

#User Definition

DEFAULT Auth-Type := Accept, Calling-Station-Id == "905308555162"

Framed-IP-Address = 192.168.10.1

Framed-Protocol = PPP

# On no match, the user is denied access.

DEFAULT Auth-Type = Accept

Fall-Through = 1

DEFAULT Framed-Protocol == PPP

Framed-Protocol = PPP,

Framed-Compression = Van-Jacobson-TCP-IP

DEFAULT Hint == "CSLIP"

Framed-Protocol = SLIP,

Framed-Compression = Van-Jacobson-TCP-IP

DEFAULT Hint == "SLIP"

Framed-Protocol = SLIP

How should we define users for SLIP protocol with Cisco 887 Vag?
