I am pinging a connected host.
The samples are the odd packets in a total of some ~62k packets, and
the intervals were similar enough for me to call it a pattern, but
you're free to call it what you want of course :)
What I implied with the spanning-tree comment was that spanning-tree
was running in a network with only one switch in total. The network
exists only between a few hosts, and there are no users or network
admins involved other than me, so I can say for sure than spanning-tree
is not needed. The configuration I found (when taking over the
responsibility) had the described portfast settings.
There are no port errors, no packets other than what the counter calls
just plain "packets", and no err-disabled. Duplex and speed are set in
both switch and hosts, and the cables are short and tested ok. All
patch cables go directly to the hosts, there's no patch panel, and no
cable runs I cannot see. Spanning-tree instability was what I suspected
at first, but wouldnt 'debug all' yield something about this?
My primary suspect right now is the hardware, but I'm generally not all
that impressed with the quality of 29xx-series hardware so I might be
inclined to draw that conclusion too fast... The POST is ok, but I
might do some more interesting diagnostics in ROMMON?
