Thanks.. I believe it turned out to be devices sticking in the "preauth"
role that
were not yet registered. The commonality of all the epsons focused on
them instead
of the issue. They're defensive IP policy must have been triggered by
the locked
down role.
Does anyone know offhand, how to ageout devices quickly from a preauth
role that's
not the default system preauth role.
thanks

Just a thought but do you have multiple helper addresses configured
for that vlan/subnet? I'm wondering if maybe the printers aren't
expecting that. Another random thought, if they're not broadcasting
for a lease because they require a static could they have maybe all
self-assigned themselves the same IP and are discovering each other
over L2?
Good luck. We're pretty much going down the same CPPM/Airgroup path
right now.

First Semester supporting mDNS in production with Aruba Clearpass
Airgroup.
Almost every Epson XP series printer is complaining of duplicate IP
addresses
which of course is not the case. Anyone see anything similar? There
are a few
older web searches about Epson's requiring a static IP, which isn't
an option right
now unfortunately.
Only Freshmen moving in today (~5K), the bulk (~20K) will arrive
tomorrow and
throughout the week.
ArubaOS 6.5.3.2
CPPM 6.6.7.96909
Four 7240 controllers
~3200 APs
Three primary SSIDs: eduroam, Devices, Guest (clearpass)
thanks

On this end, we are doing OK halfway to our expected total daily
peak clients (we’re at 15K now high water mark).
Our significant WLAN-related changes since end of Spring semester
* Running 8.2.151 on our 8540s
* Significant quantities of Wave 2 APs
* ISE as RADIUS (only, no NAC, no onboarding)
No changes to:
* our guest WLAN (Clearpass/an Aruba controller pair)
* onboarding (Cloudpath Wiz)
* overall topology
* open network in dorms for gadgets
* non-use of AVC, it crapped out and never got solved after
hundreds of hours with TAC
Fears:
* We haven’t yet hit the scale that will reveal problems with any
of the newer stuff listed above
Anyone else care to share?
