Folks,
This is what we do here to monitor Stackable Cisco 3750's - it fits
our requirement - which is to know if there has been a failure of a
stack module.
We've tried
a) looking for a "global status" variable in the Cisco MIBs - No joy !
b) monitoring traps emitted by the switch - possible but not really
what we want
c) with recent switch firmware (12.2(25)SEE1) - monitoring the
interswitch links. We make these as small as possible on a map (see
below) - but because they are 'not hidden' - then intermapper will
warn when one of these interfaces fail. (ie we use the standard Cisco
process & memory pool probe & from the interfaces window hide all but
the interfaces entitled "StackSub-St1-1","StackSub-St1-2",
"StackSub-St2-1" etc)
How we put a 3750 switch on an intermapper map (using Intermapper 4.5.x)
0) Add the switch to the map as usual
1) Set the interswitch interfaces ("StackSub-St1-1" etc) to display
(hide the rest) (from Monitor Interfaces)
You can leave it like this - but if you want to hide the interswitch
links from view then
2) Delete the label from each of these ports (from Format Label -
unfortunately one a at time - Intermapper folks - the Hide Label tick
box doesn't work if selecting multiple ports).
3) Select all these "port icons" & from format Icon choose an icon of
type Built-in shapes/text. This removes the default network/port oval
from the end of the link.
4) To hide the Interface Links from view - move them over the icon of
the switch itself - this effectively "hides" the interface links
from view - but they are not hidden in the Intermapper sense - so
Intermapper will alert/alarm etc when one of these interfaces fails.
The downside of hiding from view is that if someone hides ALL the
switch interfaces - then you've lost your monitoring of the
interswitch links - but they can be made to be less invasive as per
steps 2 & 3 - it just looks like you've got a "prickly" switch ;-o
Hope this helps
Regards
Stewart
