1787.1 | Please use HUBwatch HELP... Our writers are the greatest !!! | SLINK::HOOD | I'd rather be at the Penobscot | Thu Dec 15 1994 14:26 | 27 |
| Nice idea. However...
The find address function is *designed* to work only for stations connected
to repeater ports. Quoting directly from the HELP text you get when you
press the "HELP" button in the Find Address window...
+---------------------------------------------------------------+
| |
| Find Address Window |
| |
| Open the window to search for an Ethernet station |
| by MAC Address, DECnet address , DECnet name , IP |
| address, or IP name . |
| |
| Note |
| |
| The Find Address function only finds stations that are |
| connected to repeater ports. |

+---------------------------------------------------------------+
If finding addresses on terminal servers, bridges, and switches is important,
please contact the HUBwatch product manager, Jack NAC::Forrest. This is not
planned nor scheduled for V4.0.

1787.2 | Thanks | NAC::LICAUSE | | Fri Dec 16 1994 12:44 | 11 |
| Thanks,
this is definately a shortcoming.
It would seem that the most appropriate way to do a find address would
be to look only in the bridges, allowing a much faster search time.
This would isolate to a particular hub or hub group. Then allow
hubwatch to selectively search for addresses on particular hubs or
devices.
I'll send mail to the product manager.

| But also keep in mind a find on an address from a group of bridges would be
inconclusive. The same MAC address can appear in any number of bridges'
forwarding databases...

A well constructed find-address function for a set of bridges would
display not only the ports on which the address was seen, but also
those ports where the bridge was the designated bridge for the LAN
(that is, the port in the direction of the packet source).
For example:
Address 08-00-2B-55-66-77 found on:
Bridge Port
office_wge 1
netcad_wge 1
hubwatch_giga 22
lab_wge 3 *
blue_wgb 2 *
* indicates that the address is not on the same port
as the spanning tree root.
This requires some understanding on the part of the user on what a
spanning tree is, but the present situation (requiring the user to
perform the same search manually one bridge at a time) requires more.

1787.5 | Find Address, should do exactly that... | MSDOA::REED | John Reed @CBO, (803) 781-9571 NIS Networker | Mon Dec 19 1994 17:30 | 18 |
| I second that request. I have a command procedure that I run (from
DCL) to poll all bridges, and create listings periodically, and do
ascii searches for address informration. This only works on bridges
managable from MCC and ELMS. I use this function very frequently,
every time I try to find an offending node, for any reason. Knowing
your spanning tree and which bridge port an address was last seen is
CRITICAL to a network manager trying to find a babbling NIC, or someone
breaking into the non-managed (coax) section of his LANs.
PLEASE provide something for HUBwatch that could perform the same
function to any repeater card, or Bridge port. The older legacy
bridges would be nice too, and perhaps Vitalinks, and then there's
CISCO, and UB, and Wellfleet, and Newbridge, and 3com, and ..... .. ..
Sorry,
JR
