3808.0. "Tbl Forming an FDDI Ring on DEChub900 BP" by SCASS1::EWISE (Pobodys Nerfect) Fri Aug 23 1996 20:40

I have a DEChub900 with a DEFBA and a DEF6M in it.

All items have been taken to the latest firmware that was on Gatekeeper as of
1-Aug-1996.

The trouble is as follows.

I have taken the DEFBA (DECswitch 900 EF) and made the 1a/b ports FDDI with A
to the front and B to the back.
I have taken the DEF6M (DECconcentrator 900 MX) and made the A/B with the A to
the back and the B to the front.

I have created an FDDI LAN in the DEChub900.

When I drag the B on the DEFBA to the FDDI ring in the DEChub900 it connects
fine. It then states that I should drag the other side of the ring right away.
I clear this message box and try to drag the port on the DEF6M to the internal
FDDI ring. The ring IS NOT grayed out and when I release the connection it
sticks to the line and the ring colors match. after about 15 seconds I get an
Add Failed message.

I have tried reversing the A/B Front/Back between modules. I have tried
changing slots. I can form a ring with the A/B on either module to the back and 
connected to the internal ring.

This is at a School and I can only get a network outage not Sat/Sun sooo since
it is a new install the 800 help desk will not talk to me.

I now have the DEFBA/DEF6M connected with all A/Bs to the front and a jumpered
between the modules bypassing the backplane. 

Their is a campus ring in place that has been working fine for over 2 years.

Thanks for your help in advance and I hope someone points out some obvious
error to me.

3808.1	Not the lastest firmware on gatekeeper	NYOSS1::HERENDEEN	Tom Herendeen, 508-888-3239	`Sat Aug 24 1996 02:38`	16
	don't use gatekeeper.dec.com the firmware is ALWAYS out of date. use http://www.networks.digital.com/dr/hubs/firmware/ if you are out side the firewall. Inside the firewall, use http://npbww2.hpn.lkg.dec.com/dr/hubs/firmware/. After you pull down any new firmware, don't forget to modify your DCFFILE.DAT file too. The other thing I should ask you is if you created your backplane FDDI ring in the LAN interconnect view. I had some problems with the DEFBA V1.5.2 and the DEF6X V2.x until I created the ring. What version of HW/MCM are you using? Good luck Tom Herendeen NPB SE

	Re .-1 I used http://www.networks.digital.com/dr/hubs/firmware/ and I updated my DCFFILE.DAT file. I created my FDDI Ring in the LAN interconnect view. I am using clearVISN version 5.0 DEF6M is version 3.24 and defba version 1.61 HUB900 version 4.20 Thanks... Still looking for the something stupid I've done. Efw

	>When I drag the B on the DEFBA to the FDDI ring in the DEChub900 it connects >fine. It then states that I should drag the other side of the ring right away. Actually, it connects the port on the screen, but has not told the hub anything yet. Only when the second connection is made does MCM transmit the connect request to the hub. >I clear this message box and try to drag the port on the DEF6M to the internal >FDDI ring.

When you get the add failed message, is there supporting information in the message box? Are these the only two modules in the hub? So there is no backplane contention. Is it possible that you are using the read-only community string, when you should be using the read-write community string? -mike
3808.4	More Facts	SCASS1::EWISE	Pobodys Nerfect	`Mon Aug 26 1996 17:10`	11
	re .3 The message box only states "Add Failed" "public" is the Read/Write name Other modules are in and or out depending on my which of the multiple configurations I have tried. I have tried two Backplanes as well. Efw Still lost in the Ether
3808.5	need more info	NETCAD::CURRIER		`Tue Aug 27 1996 14:16`	6
	Please describe all the LAN backplane connections that exist prior to your attempt to connect the FDDI ports to the backplane. -sheila
3808.6	Slim Pickins'	SCASS1::EWISE	Pobodys Nerfect	`Tue Aug 27 1996 15:26`	5
	Default Thinwire that is always present. New FDDI Ring. That is all... Efw
3808.7	my $.02	CSC32::D_PERRIN		`Fri Aug 30 1996 21:00`	5
	It looks like you are doing everything right. FWIW, I see that you've tried two backplanes, but I recently had a hub that was behaving very strangely when I tried to make backplane connections and doing a "reset to factory" was the only thing that cured it. Just something else to try. Ditto on both modules.
