<DIV style="FONT: 10pt arial"><B>Subject:</B> [cisco-voip] Redundancy to the
endpoint</DIV>
<DIV><BR></DIV>Cisco's campus model stops being redundant at the access layer
switch, which <BR>(according to cisco) should have high port density.
When one of those <BR>fails, devices connected to those dense ports go dark if
they're only <BR>connected to one switch. We had a 3750-PoE-48 go down
last Friday, and 48 <BR>phones are now blank. Cisco initially said they
didn't have another one to <BR>send us until July 21, but I persuaded them to
send a 3560 as a temporary <BR>replacement, so with a minor configuration
change we should be back in <BR>business later today. Nevertheless,
losing 48 phones is still a big deal <BR>for us, and even if we had the money
to support a fully-redundant switch, <BR>there's still a significant outage
while the fault is detected and the patch <BR>cables are swapped. I
wonder what other folks do in anticipation of a <BR>high-port-density switch
failing, and if there's a likelihood of improved <BR>redundancy at this level
in the future?<BR><BR>Mike Armstrong<BR>UF/IFAS CREC<BR>Lake Alfred, FL
