3636.0. "About versions of firmware?" by NBOFS1::JAKOB () Wed Jun 19 1996 04:16

    
    
    Hello,
    
    
    what happens, when I have not the actual versions of firmware
    in the hub and the modules?
    
    For example:
    
    Hub900      V4.1.1
    EF-Switch   V1.5.0
    Conc.900MX  V3.0.1
    
    Hubwatch V4.1.1
    
    
    Does this have an impact on any thing in the network?
    
    (In this example my customer has performance problems in his network
    and on the FDDI-ports in the Switch 900EF the incoming frames/sec are
    about 80000 - 100000; hubwatch shows an fddi-util. of 40%; an
    FDDI-probe shows an FDDI-util. of about 10%)
    
    Can anybody give some hints?
    
    Thanks 
    
    Herbert

	Your customer may simply be seeing void frames if the Ring Purger algorithm is turned on (which is the default, I think) for any of the Digital boxes on the ring. If this is the case it would not be causing him any network problems because it uses "extra" bandwidth that is not being otherwise used. He may want to look at the line counters of the systems having problems to track down his performance problems. At the US CSC, we usually recommend that customers go to the latest- and-greatest firmware first, and THEN we see if there's a problem.
