We are collecting counters on all our switches (scripting)
and looking at which ones are moving significantly

Question somewhat related to this topic? How are you guys getting your
stats to find out exactly how many users are using the wired ports?
Are
you just looking at the DHCP leases or do you assume that every port
that is enabled is used?
I'm asking this question because in our dorms all of our Ethernet
ports
are enabled. When the students pay for their dorm fees, they actually
pay for the network port, whether they are going to use it or not.
We are currently in the process of installing wireless in all of our
dorms. Part of the agreement was that we would not use the existing
wired ports (we have one port per bed). We have planned for a high
capacity wireless network, using 802.11n, and 40 MHz bonded channel on
5GHz only, 20MHz on 2.4GHz. Our logic was that even though we are
pretty
sure that most of our students will make the switch to wireless once
it
becomes available, we wanted to maintain the wired ports in place for
those users that need higher capacity or reliability. So this has
made
it a little difficult in the installation phase, specially in most of
our buildings that are built like bomb shelters; walls with chicken
wire, lots of cinder block, ceramic tile, etc. really fun stuff.
Needless to say, we are having to install most of our APs inside the
dorm rooms. This is where a good survey really pays off. I personally
would not feel 100% comfortable with a wireless-only service.
Especially
if you are going to enforce some type of 802.1x/EAP security scheme.
There is a chance that you would run into that one computer that just
can't stay connected to the wireless. And if that situation ever comes
up, you can always count on the wired alternative.

We are seeing the same usage stats on wired ports here as well. The
last time we checked it was actually around 92% of ports not being
used.

Mike-
We are 100% covered with capacity-driven wireless in our residence
halls. But, we still have at least a wired port per pillow. That being
said, we now see our once-busy wired res nets running between 75-90%
idle. A lot of ports just sitting there...

Subject: [WIRELESS-LAN] Wireless-only in residence halls
Wondering if anyone has successfully implemented a wireless-only
network
in their residence halls. If so, how is it working out?
Was this a planned migration away from an "aging" wired jack
infrastructure or was it new construction? Are you doing this with
802.11n, b/g, a or "everything? Any pitfalls? Did you still leave
"some"
client jacks around or were you able to go "full-blown" wireless?
We have older (Cat 3 or worse) horizontal and are starting discussions
around abandoning the wires and just installing home runs for APs.
Any fresh advice would be greatly appreciated (saw an old thread from
2005).
Regards,
Mike
