781.0. "Notes from testing T2.8" by OSL09::OYVINDC (�yvind Christoffersen) Tue Mar 01 1994 15:13

Hi,
I have been testing T2.8 for a couple of days 
and here are my findings. Overall, I think 
HUBwatch has a very good look and feel and 
please excuse me if I have misunderstood some 
function.

(1)Moving the thresholds on the dials can 
cause hw to crash. When I move the "yellow 
threshold" on the frames/s dial to the point 
that it goes yellow and then move the pointer 
towards the center of the dial without 
releasing the mouse button, hw crashes with 
an Application Error window coming up reading 
"Floating point error :invalid".

After restarting hw I immediately get a 
window labeled "HUBwatch: Error" displaying 
"No buffer space is available. The socket 
cannot be created. Please restart IP network 
service."

(2)Also, after setting a threshold, it leaves 
a line at the bottom of where the 
alphanumeric box appeared.

(3)I did not find any help on how the 
thresholds on the dials could or should be 
used. Can they be saved and also are they 
functional when viewing the "Repeater 
Summary" window?

(4)Clicking Help in the menu Adding and 
deleting communities: The help text uses the 
term Agent box and this is not entirely 
precise. Is it the "Agent File" field?

(5)In the help menu, the reset button in the 
Performance field is called "Reset" only and 
not "Reset Peak" as is displayed.

(6)After enabling security on a port and 
exciting back to the "Repeater Port Summary" 
window, you must make a refresh to see the 
effect in the Security field, not very 
logical.


"Wish list"
After starting HUBwatch, you should be able 
to select amongst those agents stored in the 
hw_agent.dat or enter a new one. In T2.8 the 
latter is default. 

When enabling port security, I find it 
practical to go from the "Repeater Summary" 
window to the "Repeater Summary: port 'n'" 
window and there read the MAC address from 
the field "Last source address seen". Then I 
open the security window and enter the MAC 
address. This is tedious because you cannot 
cut and paste between those fields. I think a 
defaulting of the MAC address or a 
cut-and-paste is needed until we have 
autosecurity (in the summer?).

Regards,
Oyvind.
