953.0. "Sniffer port for monitoring" by NETRIX::"[email protected]" (Youda Kopel) Fri Mar 21 1997 03:20

Hi There ,

Is there any way I can connect a Sniffer ( Network General ) between FGL-4
and a Server ( Full Duplex ) for protocol trouble shooting ????

Will we support this feature in the future ???

Many Thanks in advance ,

Youda Kopel ,

953.1does N&G have a pod for this.KERNEL::FREKESLike a thief in the nightFri Mar 21 1997 12:168
    This depends if the sniffer has the correct pod, that can sit between
    the two stations, and just listen to the data as it passes. 
    With out actually becomming an active station. 
    
    I am not sure if the GIGaswitch supports port mirroring. Perhaps there is
    someone else who could answer on that one.

    It doesn't support port mirroring, if I correctly understand what you
    mean.  You can't configure port 1 so that it will spit out the same
    stuff that comes out port 2.
    
    Sorry

       ...and putting an analyzer between two devices is not something
    which requires "GIGAswitch/FDDI System support".  It is external to the
    GIGAswitch/FDDI system operation.
    
        ...any analyzer which does not have an active MAC (I.E. sometimes
    referred to as "passive monitoring") should be able to be placed on a
    full duplex connection without breaking it.  Sometimes, this is
    achieved with a "splitter" cable.

953.4works half way...MAASUP::PORAMBOTue Mar 25 1997 11:5013
    
    
      I was working with the local Network General rep concerning this
    issue. Evidently this comes up a lot in their sales into Gigaswitch
    customers. 
    
      We placed the Sniffer in a full duplex connection with a beam
    splitter cable, analyzer in passive mode. What you see on the trace is
    only one of the two conversations on the link. It makes sense since
    the analyzer only has one "RX" port. They may be working on this but
    don't quote me on it!
