DHCP option 78 with multiple controllers?

DHCP option 78 with multiple controllers?

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

Hi,

please check if you have duplicate IP anywhere?tracert..
Or you have 2 DHCP Server which causing issue during providing/getting IP for the AP.
Try to set a static IP on the AP.

Good luck.

Seems like the controller is not answering the ap's request. Without looking at the big picture (full configs and logs) it's hard to tell what's wrong. I would suggest contacting the GTAC - https://www.extremenetworks.com/support/contact/

When you mentioned this in the original post, wouldn't think the ap reg check box would be the issue.

Ah, thank you Craig. It wasn't obvious from the documentation that the administration / management port could not be used for AP registration. I'll give this a go now.
