2878.0. "HUBwatch/Windows V4.1.1 limitation w/ routing switches" by STEVEV::VINGERHOET () Wed Oct 18 1995 13:37

Folks,

I wanted to let everybody know about a bug in HUBwatch V4.1.1 for Windows
ONLY. HUBwatch has a bug where the TELNET window is invoked rather than the 
Expanded Lan Interconnect View for the DECswitches w/ routing code.

The limitation is that only four pulldown stubs can exists for a module
on the normal Lan Interconnect View. You can either do four ethernets or
three ethernets and an FDDI connection before being limited by the bug.

There are two workarounds: use cables to use the front panel ports or
use the OSF version.

This problem has been escalated. It has not yet been determined when a
new version of HUBwatch will be available.

2878.2A workaround to get five Ethernets and the FDDINPSS::WADENetwork Systems SupportThu Oct 19 1995 16:3929
                             
    The following is a workaround for this if your customer ABSOLUTELY MUST 
    (you'll see why I say this later) have five, not six, Ethernets ports and 
    the FDDI port connected to the backplane.
                                
      	- redirect four (any four except port 3) Ethernet ports to the back
        - connect those four to your backplane Ethernet lans
    	- redirect the FDDI port and port 3 to the back
    	- connect the FDDI port to the FDDI lan and port 3 to the thinwire
    	
    Six out of seven isn't too bad but its better than four.  And, as always, 
    there are some (actually two) gotchas.  The first is that you need to 
    remember which backplane lans the four Ethernet ports are connected to as 
    they are now grouped into one pulldown stub.  The second gotcha is the one
    related to ABSOLUTELY MUST; if in the future you need to reconfigure 
    any Ethernet port except port 3 you need to do the following -
                              
    	- disconnect the FDDI and port 3 from the FDDI lan and the thinwire
    	  lan
    	- redirect the FDDI port and port 3 to the front.
        - then the four Ethernet pulldown stubs can be independently 
          manipulated 
    
    		Your customer most definitly won't like this part about
    		reconfiguring unless he absolutely needs five Ethernets and 
    		the FDDI connected to the backplane.
                                                                 
    Bill                                                                

2878.3Thanks for heads upANGLIN::BERNDTFri Oct 20 1995 17:585
    Bill and Steve:
    
    Thank you for the heads up... it really is nice to know about this
    before the customer finds it, we can be more effective and proactive.

2878.4Patched versionSTEVEV::VINGERHOETTue Oct 31 1995 12:5211
I've created a new version (V4.1.2) of HUBwatch/Windows that should fix the
problem describe in the base note ONLY.

This version should ONLY be used to get around this problem. There are NO
plans at this time to release this version to SSB.

The kit can be copied from the anonymous FTP area on the node BHUB under
the directory "route_pc". The directions are similar to those provided in
Note #8.7.

2878.5what does 4.1.2 fix?CSC32::J_SHUMWAYWed Nov 01 1995 11:554
    I have installed V4.1.2. I see no difference. Double clicking the
    module in the main screen or the Lan Interconnect screen launches
    a telnet session. I can still only get 6 of 7 lans to the backplane.
    What does this fix? Have I missed something?
2878.6use the expand buttonCSC32::J_SHUMWAYWed Nov 01 1995 12:214
    Oppps, if single click the module then click on expand, the Lan
    Interconnect for the slot is displayed and can manage all ports.
    
    thanks for the fix
