959.0. "Problem with Linecard DVT if 6 x FGL-4" by FRSIT::MAYER () Thu Mar 27 1997 11:38

Hi,

I'm just installing 4 GIGAswitch's/FDDI. Each equipped with 4 FGL-4 and 2 FGL-2.

We are using FW Rev 3.1 on all modules except the clock wich is 3.0.

If I want to examine the Linecard DVT it take minutes to get the DVT prompt
or even the connection gets a timeout.
If get a prompt from the line linecard the output is very slow e.g. 1 or 2
charactes per second.

If I power of one of the FGL-4 (makes no diffrenet which one) the DVT works
normal.

So it looks to me that if all six FGL-4 are up, we have problem with the DVT,
if we have less then six FGL-4 up we have no problem.

For the customer environment this means that in case of problem we have nearly
no chance to examnine the DVT.

This problem is reproduceable on all four switches.

Regards Juergen

        Yes - this is known, although undesireable behaviour.  The DVT
    monitor was not intended as a tool for field or customer personnel, and
    there are some problems associated with using it as such.
    
        It is a known deficiency that the DVT monitor on FGL-4s loads very
    slowly or not at all in certain configurations.
    
        There are several improvements which are either in discussion or in
    the development stage.  Of most value to field personnel is the
    proposed addition of error logs to the GIGAswitch/FDDI system MIB
    (SNMP).
