I think I have a LLC2 problem. Is there any details I should collect
or is it really obvious what the problem is? My apologies I am a
X.25 newbie of 3 days.
[ p.s. I have modified the addresses for security reasons but they
are same length]

I should add that I have followed the steps in the Problem Solving
Guide and ended up in Section 2.4.3 LLC2 Link set up failure.
I have checked everything, and as far as the untrained eye can see,
everything looks ok. I run ctf trace as suggested and all I see is
16:38:10.60| Tx| 6| 7E 7E C P XID Id=81, Type=03, Window=127
16:38:11.61|AKTO| 0| Ack Timer Expired |
16:38:11.61| Tx| 6| 7E 7E C P XID Id=81, Type=03, Window=127
16:38:12.61|AKTO| 0| Ack Timer Expired |
16:38:12.61| Tx| 6| 7E 7E C P XID Id=81, Type=03, Window=127
Which looks like lots of requests being transmitted but not being
acknowledged by the X.25 server. Is this correct?

You are not receiving any frames so the link cannot be established. You will need to be sure that each system has the correct MAC address in the LLC2 SAP. Also, be sure that the LSAP Address matches at each end. This is setup within the configurator, it's best to check these from the configurator by selecting 'Modify Existing Configuration' (wording may not be correct), then navigate your way to the LLC2 DTE. From there select the DTE you're interested in, and check MAC Addresses and LSAPs. If you still can't figure it out, you can paste those screens in as a reply, and I'll take a look when I get a few moments. If you still can't get it going, it would be helpful to see a trace from both systems. Regards, Matt. | |||||
| 880.3 | now using GAP | FORTY2::JONES | Neil | Tue Apr 15 1997 18:57 | 10 |
I think what I was trying was unsupported. PSI does not support
LLC2 on VMS 6.2 (the access node was VMS)
I have abandoned this approach. We have installed PSI on the client
system and everything is ok as we are now using the GAP protocol.
Apologies for any wasted time, I am very new to X.25...
