2078.0. "Can't find address of Hubwatch ws from DECswitch" by 36932::STUART (Scott Stuart - NPB SE - 410.315.9954) Tue Mar 07 1995 20:33

    I cannot find the address of the station from which I am running
    hubwatch from the DECswitch 900EF screen.  I an running HUBwatch under
    OSF connected via a fiber ethernet repeater to a DR900FP and connected
    to bridge port 3 on the DECswitch.
    
    When I try to find by IP address it pings my own address successfully
    but does not return a MAC address.
    
    Is this the expected behavior?
    
    thanks ...scott

I don't understand what you mean.  Do you mean in the DECswitch's forwarding
database, or do you mean the HUBwatch Find Address screen?

Note 1787.* discusses Find Address.

The <HELP> button in the Find Address window says

                                  Note

      The Find Address function only finds stations that are
      connected to repeater ports.


Is your station on a hub repeater port?  Is the repeater connected to a hub
that is listed in your agents file?

2078.4...was looking in forwarding database36932::STUARTScott Stuart - NPB SE - 410.315.9954Fri Mar 10 1995 08:4514
    re:.2
    I went back out to the customer sites yesterday and I was wrong about
    which find address I was using.  I was looking in the switch forwarding
    database and the all IP addresses were found on the correct bridge port
    except that of the workstation where HUBwatch was running.  It appeared
    to do t ping and check the arp table, but came up with
    
    MAC addresss translation failed - node unknown to system ...
    
    Is this the expected behavior?
    
    thanks

    The "FIND" in the switch's forwarding database window searches ARP
    cache of the system where HUBwatch is running, when you use IP address 
    option. ARP cache of a system does not keep its own address in its
    database. That is why FIND comes back with the message "MAC address 
    translation failed" when you tried to find the system which you were 
    running HUBwatch.
