(ASCEND) Max2000 <-> Cisco 4500

[Klaus Noack <k_noack@syscomp.de>]

Hello,

I have a problem calling a Cisco 4500/11.3 with our
Max 2000/5.0Ap51

I try it with following nvram-profile:

I get the following wandisp 64 output via hex2ppp and vi 
(http://www.mlink.net/~vandry/hex2ppp.html) with my commments.


XMIT-18:: LCP ConfReq <id=1> <mru 05f4> <endpoint 03 00 c0 7b 6d b7 fe>

XMIT-18:: LCP ConfAck <id=165> <auth c2 23 05> <magic c4770730>

Good LCP is OK

RECV-18:: CHAP ...
XMIT-18:: CHAP ...
RECV-18:: CHAP 03 c3 00 04

Good CHAP is OK

RECV-18:: CCP ConfReq ae 00 0a 17 06 00 01 02 01
RECV-18:: <proto=8207> 01 97 00 04

I think Cisco want to do 82 07 "Cisco Discovery Protocol Control"

XMIT-18:: CCP ConfReq 01 00 09 11 05 00 01 03
XMIT-18:: IPCP ConfReq <id=1> <addr 172.29.24.2>

I think Max want to do IP

XMIT-18:: CCP ConfRej ae 00 0a 17 06 00 01 02 01
XMIT-18:: LCP ProtRej 03 00 0a 82 07 01 97 00 04

Max don't want 82 07 "Cisco Discovery Protocol Control"

RECV-18:: CCP ConfAck 01 00 09 11 05 00 01 03
RECV-18:: LCP ProtRej a6 00 10 80 21 01 01 00 0a 03 06 ac 1d 18 02
RECV-18:: CCP ConfReq af 00 09 11 05 00 01 01

Cisco don't want IP

XMIT-18:: LCP TermReq 01 00 04

Max says: good bye


I think this is a Cisco problem with IPCP.
Can anybody tell me, what I or the Cisco admin can do?

If anyone need the cicso debug protocoll, I can mail it (it is very long).

TIA
