HOWTO connect MCI using Netgraph + Frame Relay with Digi SYNC/570i

[John Mok]

Hi,

I would like to replace the existing Cisco router 1600 and connect to 
MCI Hong Kong with FeeBSD 5.3 box with a Digi SYNC 570 serial card. With 
reference of the FreeBSD handbook and the information from Julian 
Elischer at

http://www.elischer.org/netgraph/

I have compiled the kernel with the following options :-

....
options NETGRAPH
options NETGRAPH_FRAME_RELAY
options NETGRAPH_LMI
....
device  ar

The dmesg showed that the device ARNET/Digi SYNC/570i was loaded 
successfully. However, when I tried to config. with the following, the 
ngctl prompt with the error:

#ngctl mkpeer ar0: frame_relay rawdata downstream
#ngctl mkpeer ar0:rawdata lmi dlci500 ansi
ngctl: send msg: No such file or directory

I tried the testing with MCI connection disconnected. How do I set the 
line speed to 1536 Kbps? I hope someone could help me how to config. the 
netgraph with work with Digi SYNC/570i

Thanks a lot.
