Consider setting up a separate zone or zones (via VLAN) for devices
with embedded TCP/IP stacks. I have worked in several shops using
switched power units from APC, SynAccess, and TrippLite, and find that
the TCP/IP stacks in those units are a bit fragile when confronted
with a lot of traffic, even when the traffic is not addressed to the
embedded devices.
Yes! This.
I used to have my PDUs/term serves/switches all on one VLAN. As growth
occurred, they get broken out to dedicated VLANs. With that, the amount
of false positives from Zenoss went way down (frequently port 80 would
report down, then clear). I still get some alerts, but far less
frequently.
