Dear Roman,

Thank you for your information. I have succeeded to setup the frame relay using netgraph. However, I failed to get the interface ng0 up :-

#ifconfig ng0 1.2.3.4 255.255.255.0 up
ifconfig: interface ng0 does not exist

Please help to advise how I could make the interface ng0 appears.

Thank you,   John Mok

In case you still need this information.

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 mkpeer ar0:rawdata lmi dlci0 annexD

also you need NETGRAPH_RFC1490

ngctl mkpeer ar0:rawdata rfc1490 dlci500 downstream
ngctl mkpeer ar0:rawdata.dlci500 iface inet inet


did the last command do anything?

please show the output of:
ifconfig
ngctl list



and you will get smth like ng0


Best regards, Roman Kurakin


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.

John Mok
