Howdy,
I am currently testing two C35 controllers - as part of our testing we were able to get some access points provisioned fine on a subnet existing on the two controllers in a HA pair.
However, I have been trying to get the access points to provision on an external network using DHCP option 78. The attribute string I have tested with is 1 0.0.0.0 1.1.1.1 in hex without spaces however the access point does not seem to pick this up - at least not visibly.
Nothing in /tmp/log indicates the DHCP options have been picked up, there are also several entries with:
Mar 21 13:10:37 cap: 01090:ru_connect_to_ma.c:991-ru_connect_to_ac_ru_manager()- IP https://devices.extremenetworks.com, state URL_ITEM_STATE_PENDING, flag URL_ITEM_FLAG_STATIC_HWC, retries 2, timestamp 55000, standby 300000 pversion 2 Mar 21 13:10:37 cap: 01090:ru_connect_to_ma.c:1016-ru_connect_to_ac_ru_manager()- HWC IP https://devices.extremenetworks.com, state URL_ITEM_STATE_PENDING, diff_ticks 1000, TO_ticks 300000
On a likely unrelated note, we're not able to get it to statically provision either using:
cset authip 1 0.0.0.0
capply
csave
reboot It shows the following logs:
Mar 21 13:28:31 cap: 01090:ru_connect_to_ma.c:1016-ru_connect_to_ac_ru_manager()- HWC IP 0.0.0.0, state URL_ITEM_STATE_NO_ANSWER, diff_ticks 2000, TO_ticks 5000
Mar 21 13:28:32 cap: 01090:ru_mgmt.c:2741-whsl_trans()-S_EDISC 159It is able to communicate fine with the controller and curl the web interface of the controller just fine.
Any ideas here?
Thanks

Unfortunately, exactly the same issue here.

I have tried both 1 0.0.0.0 1 1.1.1.1 and 1 0.0.0.0 1.1.1.1 in HEX, obviously without spaces. There aren't many useful entries in the log, but if it was working I would expect it to pick up the controller's IP address.
Also any ideas why the static provisioning isn't working either?

Option 78 should be 1 0.0.0.0 1 1.1.1.1

I'm guessing you're asking the vendor of the DHCP server - it's Juniper, and the configuration is fairly generic and straight forward. I've simply inputted the HEX values directly on DHCP option 78.
Is the format I have provided correct? This isn't clearly documented in any of the GTAC documents.
Statically setting it is not preferred as we have many AP's to deploy at various different sites and it's massively impractical. However, for testing purposes I have already completed the steps in that GTAC article and that also does not work (snippets from the log are provided in the OP).
I appreciate there are probably two different problems in play here - the DHCP options not being picked up, and the fact that the access point isn't able to provision in the first place.
