RE: PLS HELP - DLSW+ not working, token-ring attached FEP 3746 to a ethernet attached SNA client over Frame-relay...
If anyone is interested, I have written a javascript on one of my web pages
that will calculate the canonical MAC address of whatever you enter. The
URL is http://michael.gargantuan.com/network/calcmac.htm if you want to give
it a whirl
HTH,

ITYM read *each nibble* from left to right, not the whole 48-bit string.
A simpler way to say it is "read each *byte* from right to left." This
combines steps 2 and 3 below.

heres an example of conversion:

write it in binary
0110 . 0011 0101 . 1000 0100
read it from left to right
0060.0caf.0102
swap the nibbles
0006.c0fa.1020
Thats it

Mohan , The problem is right here ; 04:38:03: DLSw: CONN: peer 150.150.1.1 open failed, unreachable [17] This is one (possible) reason why dlsw is not working . Try to do an extended ping between the dlsw peers . If you get this working the dlsw peers will come in a connect state . On the remote router you don't need a source-bridge ring-group , so you can remove this entry . Also change the spanning tree protocol to ieee instead of dec . On the Fep side , do a 'debug token event ' to see why the router is not inserting . One reason could be a ring mismatch . flem --- Mohan [EMAIL PROTECTED] wrote: Hi gurus, i have this problem getting a token-ring attached FEP 3746 talking to a Ethernet attached SNA client over a back-to-back frame-relay network configured for DLSW+.

Joe , Dlsw peers are active peers . They need to be in a connect state . Debugs shows that they cannot connect . ( 100% sure this is a routing issue ) Don't think you are correct in your response ; Mac addresses are kept in the dlsw reachability in a non-cannonical format . This means that you do NOT need to do the conversion yourself . Dlsw will take care of this . If you are talking about translational bridging or SDLC connections you do need to make the conversion yourself . flem --- Joe Martin [EMAIL PROTECTED] wrote: MAC addresses are carried in non-canonical format in DLSW.

RE: PLS HELP - DLSW+ not working, token-ring attached FEP 3746 to a ethernet attached SNA client over Frame-relay...
hi all, a CCIE from the cisco open forum responded as below: Answer: You probably have another bridge on the ring. do the following debugs before trying to no shut the interface debug source events term mon Typically, you do not want to peer to an interface address, but rather a loopback address. This way DLSW will come to the "connected" state. This of course would not help you in this case because you have a problem on your token ring anyway. You will need to resolve that. If you have another RPS (Ring Parameter Server) on the ring, and you try to come up with a different ring number, the RPS will not allow you into the ring. i'm using a loopback interface for my peers and its not connecting, routing might not be a issue here since i have no problem to ping or connecting to the remote router unless i'm missing out something important here. secondly, there is no other ring other than ring 9 and there is no RPS server present. flem, you're right. no MAC address conversion is needed for dlsw unlike sdlc, cisco doc. confirms this. BUT, what could have gone wrong here... pls. help and thanks guys, mohan -Original Message- From: Flem [SMTP:[EMAIL PROTECTED]] Sent: Tuesday, May 30, 2000 6:23 AM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: Re: PLS HELP - DLSW+ not working, token-ring attached FEP 3746 to a ethernet attached SNA client over Frame-relay... Joe , Dlsw peers are active peers . They need to be in a connect state . Debugs shows that they cannot connect . ( 100% sure this is a routing issue ) Don't think you are correct in your response ; Mac addresses are kept in the dlsw reachability in a non-cannonical format . This means that you do NOT need to do the conversion yourself . Dlsw will take care of this . If you are talking about translational bridging or SDLC connections you do need to make the conversion yourself . flem --- Joe Martin [EMAIL PROTECTED] wrote: MAC addresses are carried in non-canonical format in DLSW. If your running a protocol converter on the Ethernet segment and have created a peer mac address, make sure you do the conversion. This is also true of any peer statements you have in the routers. I did an install like this about 3 years ago and that was the only "issue" I had. JOE CCIE #5917 "Mohan" [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Hi gurus, i have this problem getting a token-ring attached FEP 3746 talking to a Ethernet attached SNA client over a back-to-back frame-relay network configured for DLSW+. I followed the instructions and guidelines provided on the cisco DLSW+ docs, however, i fails to get the configuration work. I hope you gurus can shed some light and help me with this. the following are my observations: 1. Initially, the interface and line protocol on to0 (Hostrouter) was up, however shortly after the client was configured the interface gone into shutdown state and i fail to do a no shut, no response and remained at shutdown state, i'm only able to do a no shut after removing the souce-bridge 9 1 11 statement from the hostrouter. any idea why is this happening. I have even tried upgrading the ios from 11.1 to 11.2 on the hostrouter. 2. I have checked the cables and cards and confirm to be working fine. 3. on the remote router, the dlsw peer reach output was showing the client searching for the 3746 MAC but the session never came-up. i have attached the config. and show outputs, pls. help to get this problem fixed.
