Re: [WIRELESS-LAN] 8.3.133.0 Code with IPv6 Bug

2018-08-28 Thread Kitri Waterman 
We’re entering Fall with 8.3.143.0, no production IPv6 or 802.11k/v/r, on 
5508’s and 5520’s.

No issues so far, but we’re targeting 8.5 code as fast as possible for the 1815 
APs support.

Hi Christina,

What we see with our IPv6 wireless:

  1.  SLAAC hands out addresses, you can join.
  2.  While running  pings PCs and older MACS the pings will dropout and only 
High Sierra will come back after about 4-6 pings with a new address.

We ran some captures over the air and full communication appears to stop from 
the AP (not being a client based issue). We have a case open with TAC and we 
are pretty sure we hit a bug. We are looking forward to stable 8.5 code.

Best of luck with the issue!

We are on 8.3.143.0 on a pair of 8510s.  Had some weird behavior at the start 
that has seemed to work itself out.  Currently investigating some roaming 
issues that may or not be an issue with the code.

Another question, has anyone installed 8.3.143.0 yet?  It seems to have a 
number of fixes for 2800/3800.

Jamie,

Can you describe more the IPV6 issue with 8.3.133.0?  For about a year we have 
been running that code.  And strangely enough, we have had issues with iOS not 
staying connected when roaming.  As all modern systems try IPv6 before IPv4, if 
there is an issue with IPv6, this would explain the delay.

We are running 2 sets of 8510’s and 1 set of 5520’s on 8.3.133.0.

We are running 802.11k/v/r and it has made a tremendous difference in our 
roaming (and many less complaints). We have an IPv6 issue with 8.3.133.0 with 
IPv6. On PCs, it times out. On MACs it times out and recovers. This is not a 
production network- but it will be once we can find code without this bug. 
Otherwise 8.3.133.0 has been great.

Our CTO just mentioned this today as we have passed the peak wireless stress 
point without issues for today’s class changes.  While this isn’t answering 
your question, I thought I might share what we have.  We have close to 30,000 
wireless devices connected and have our F5 load balancing 6 VMs running 
FreeRADIUS that in turn query our eDirectory backend through LDAP.  One feature 
that you should make sure is enabled is “config radius ext-source-ports enable”.
