RE: [WIRELESS-LAN] Android 7.1.1 and DHCP issues?

[Danny Eaton]

Oddly enough, the student was out of town for the past weekend, came back 
today, and it’s working just fine.  

 

By “OK”, that is what the freeradius logs were showing; for our two 802.1X 
SSID’s, our freeradius server checks our AD for username/password, and then 
returns to the WiSM-2 clusters “staff”, “student” or “visitor”.  It was 
authenticating and authorizing the student previously, but I never saw a 
DHCPDISCOVER for his phone’s MAC address.  Today, I am.  No changes were made 
on my WiSM-2’s, SSID’s, radius servers, or DHCP servers.  And, like I said, it 
wasn’t even doing DHCP on the OPEN (captive portal) SSID.  Very strange.

By OK do you mean a Radius access-accept? That is an authorization, but doesn't 
necessarily imply any additional access parameters are appropriately set (or 
not sent). We've seen this cause issues with eduroam roaming before, but this 
can happen both on 802.1x and open (captive portal is often implemented with 
AAA via MAC). Are you able have the dump what the wireless controller sees for 
parameters and compare with a successful authentication? Or test on a wireless 
lan without AAA overrides?

 

FWIW, I'm running a Nexus 6P on 7.1.1 and no issues on our 802.1x (eduroam) or 
open captive portal SSIDs. We have Cisco WLCs against ISE.

Ar e you only looking on the DHCP server for the discover? Could a radius 
server be returning an option setting an incorrect VLAN or specific ACL for the 
client causing it to be dropped at the AP/WLC level? If it's happening on an 
open network it'd probably have to be hitting a MAC-based rather than 
user-based access rule (or possibly profiled and put in a blocked group).

If you’re using certs, there’s a setting under CA Certificate that you have to

RE: [WIRELESS-LAN] Android 7.1.1 and DHCP issues?

[Danny Eaton]

We have 2 DHCP servers that load-balance.  They are ISC (currently, we're
going to move to Infoblox, hopefully over the summer).

 

The phone (per the user): It is a Google Nexus 6P.

How many dhcp servers do you have and do you have multiple routes? Let us

Yup; that's my next plan.  Was just hoping someone else had seen something.
The phone works on a personal wireless (hot spot), but just doesn't seem to
want to do DHCP here on campus.

Are you sure the phone is sending DHCP Discover packets? You mentioned it's
not working on the open SSID, you may want to try connecting the phone to
the open SSID and capture OTA packets to see what it's doing and start from
there and move towards the DHCP server.

Are you only looking on the DHCP server for the discover? Could a radius
server be returning an option setting an incorrect VLAN or specific ACL for
the client causing it to be dropped at the AP/WLC level? If it's happening
on an open network it'd probably have to be hitting a MAC-based rather than
user-based access rule (or possibly profiled and put in a blocked group).
