1747.0. "Hub900+Pckt probe+hubwatch" by ZPOVC::AROBINDUBASU () Fri Dec 02 1994 04:12

    Hi,
    
    We are having hub900 (V3.1) installed along with decpacket probe (v2.1)
    in it. We are using Hubwatch version 3.1 in windows.We have observed
    that we cannot monitor  the packet probe thro the hubwatch . 
    
    Also the deafult connection of the probe is going to thinwire of the hub,
    and can not be reconfigured for any other flexible back-panel channels 
    of the hub.
    
    Has any body any solution for it?
    
    Thanks

1747.1PROBEwatch is what you needROGER::GAUDETBecause the Earth is 2/3 waterFri Dec 02 1994 11:269
The DECpacketprobe 90 is monitored via a separate application called PROBEwatch.  There
are numerous notes in this conference about it (DIR/TITLE=PROBE should do it).
PROBEwatch is not (yet) launchable from HUBwatch and thus must be invoked separately. 
Also, the probe is a 90-style Ethernet-only device and cannot be connected to any of
the DEChub 900 flex channels.  There is a token ring probe available (or soon to be
available) called the DECpacketprobe 900RR.  Contact the product manager Jack
NAC::FORREST for further details.

1747.2a work aroundKAOFS::S_HYNDMANAcronym Decoder Ring ArchitectFri Dec 02 1994 12:4517
    
    
    There is a way to contect the packet probe from the thinwire to a flex 
    channel if you have a Repeater 900 or Server 900.  Both of these
    modules will repeat between two segments if connected.  In hubwatch you
    will see in the lan interconnect window that the probe is on the
    thinwire.  The repeater or server has two pull downs.  You can connect
    one of the repeater/server pull downs to the flex channel you want and
    the other to the thinwire.  This effectively repeats all the traffic to
    the thinwire and the probe for monitoring.  Obviously you can use
    different repeater to monitor different channels.
    
    	Be aware however that any thing on the thin wire will also be
    connected so this may not be an option in your case.

1747.3From the SPD...SLINK::HOODI'd rather be at the PenobscotFri Dec 02 1994 13:0812
The SPD for HUBwatch V3.1 says...

           The following modules are displayed with a front bezel only. No mod-
           ule management is available for these products.

           DECwanrouter 90    DECmau 900TL
           MUXserver 90       DECrepeater 900TL
           DECpacketprobe 90  DECrepeater 900SL

    RE: .2 You CANNOT use a DECserver 900TM to repeat between channels.
    It has no intercoonect or repeater capability. DO NOT be confused
    by the 2 stubs from the icon. No.1 is for connection of the active
    users to the ThinWire or an IMB. No.2 is for a maintenance connection
    to provide down-line load or up-line dump functions only.
    
    
1747.5Better remote management?ZPOVC::AROBINDUBASUMon Dec 05 1994 01:5914
    Agree 100% with .4 . 
    
    We are allready using Probe watch software.
    
    Does it mean that every time we want to monitor a separate Lan,
    We have to go to remote place to make an external connection 
    somehow and then monitor?
    
    Will there be any provision for a software selectable flexible 
    channel , so that remote management become easy ?
    
    Thanks and regards,

1747.6Don't present them the sameKAOFS::S_HYNDMANAcronym Decoder Ring ArchitectMon Dec 05 1994 12:348
    
    .4 ok.ok.ok. Thanks for the clarification.  I was using the repeater
    connection and assumed that the server worked the same way.  Perhaps 
    the interconnect window in Hubwatch should not present the modules the
    same way.

1747.7sorry, small modules cannot hop between LANsNAC::FORRESTTue Dec 06 1994 20:309
    regarding .5
    
    The DECpacketprobe 90, being a small module, cannot connect to the flex 
    channels on the DEChub 900 backplane, only to the ThinWire channel. We
    understand this is a limitation for monitoring in the 900, and are 
    planning products to address the problem.
    
    In the meantime, the suggestion to repeat one flex channel at a time 
    onto the ThinWire is the best workaround.
