552.0. "MAP message with CISCO" by GWTEAL::WOESTEMEYER (Why??...Why not!!!) Thu Apr 30 1992 12:45

Customer attached a CISCO DAS to a DECconectrator 500, as SAS, expecting 
to get a wrap.  HE then used ELMS 'show map' and 'sh sif', the results are 
attached.  He is concerned about the message returned.

In an attempt to duplicate his condition I used a DECbridge 620 and attached
it to a DECconcentrator 500 in the same manner.  Although my may was not the
same, it did not return the errors, and returned the wrap as expected.  

Any ideas??

552.1SIF Config Index PathSOS6::GROSSETETEMon May 11 1992 10:1528
    	Steve,
    
    	I already have some problems with CISCO implementation
    of Index Path in SMT SIF Config frames. As our ELMS Ring MAP
    is based on the content of SIF Config frames, this could be
    your problem.
    
    Could your customer try a :
    elms> sho CISCO_AGS sif conf via DC500
    
    You'll also get an error message from ELMS
    check the index path info on the Cisco when attached as a DAS, 
    I think it'll be 
    	PHY 1 connected on PHY 1
    	PHY 2 connected on PHY 2
    	MAC connected on MAC
    
    It must be (ie: check on our DECbridge 620)
    	PHY 1 connected to MAC
    	PHY 2 connected on PHY 1
    	MAC connected on PHY 2
    
    Note also that CISCO performance with v.8.x are poor when
    connected as a SAS. It seems Cisco box is permanently pooling
    the status of the PHY port. Must be corrected in a next version.

552.2Sho Sif in .0GWTEAL::WOESTEMEYERWhy??...Why not!!!Mon May 11 1992 18:428
    Patrick,
    
    .0 included the 'sho cisco sif config via dc500, it had no errors. The
    customer has not tried to hook the Cisco as a DAS, but is going to
    discuss this with Cisco at Interop.  Based on the Show Sif from .0, any
    further ideas/suggestions?
    
    Steve
552.3KONING::KONINGPaul Koning, A-13683Tue May 12 1992 13:4311
The SIF info you showed in .0 indicates several errors in the Cisco station.

First of all (the cause of these problems) it says that PHY 2 is connected
to itself, and MAC 1 is connected to itself.  What it should be showing is
that PHY 2 is connected to MAC 1 and vice versa.

Second, the Station ID of the Cisco station is illegal, since it isn't a
Universally administered value.  That doesn't affect anything directly, but
it does violate the standard.

552.4Index Path is the problem.SOS6::GROSSETETEFri May 15 1992 15:257
    	Steve,
    
    	As Paul said, you are seeing the same as I had. So, I definitivly
    think that Index Path is your customer's problem.
    
    	Patrick
    
552.5Thanks to allGWTEAL::WOESTEMEYERWhy??...Why not!!!Fri May 15 1992 16:066
    Thanks to all,
    
    I have passed the information on to the customer, he will pursue the
    problem with Cisco.
