Re: 3802i and the death of autonomous ap

Steve Chapman · ‎07-26-2018

I am trying to set up a 3802i ap as an autonomous ap. I now learned that I have to run mobility express. I currently running 8.4.100 and cant get it to work. It boot up and get to the end and the light just rainbow and I never see the ssid.

So I tried to terminate the autoinstall and go manual, but the wired interface keeps flapping up and down and never connects. the rainbow lights never stop even after configuring ssid.

I did notice that this ap is only pulling 15.4 watts. I tested this on 3850s with 802.3at(30w) and UPOE (60w) and still only 15.4. this just doesn't see right.

Pls don't use 8.4.100.0, that is the only code released in 8.4.x and no one should use that code.

Try with 8.5.135.0 & things should work

problems is I we didnt purchase a service contract with this ap so I cant download new software without paying for it. It was purchased with mobility service and that is what came on it.

Steve Chapman · ‎07-27-2018

trying to get a new version from my sister campus. I think they have a contract.

Leo Laohoo · ‎07-27-2018

I don't see any issues at the output. I can see the AP boot up in Mobility Express fine.

patoberli · ‎07-30-2018

Doesn't the 3802i has it's antennas disabled if it's running only with 15.4W?
Now that the AP is booted up, is it running with 30W (check the switch) or still just on 15.4W? If just old PoE, try to force PoE+ by using "power inline full" (or similar command, depending on the switch) on the switch.

Steve Chapman · ‎07-31-2018

nevers goes above 15.4. Plugged in to a 3850 902.3at (poe plus). I also tried in a 3850 UPOE (60 watts) still no lunck.

Steve Chapman · ‎07-31-2018

the power is supplied over mgig port. Is the data supplied over the mgig or aux port?

patoberli · ‎07-31-2018

Both over the mgig port. I think there was a firmware version which had buggy CDP information (or was it LLDP?) that caused the switch to send the wrong amount of power. I think only manually setting the power, or upgrading the AP software fixed it. Don't have the bug number at hand at the moment though. Or was it a hardware series issue... hmm.
Anyway, try the latest 8.5.135.0 if you can.

Steve Chapman · ‎07-31-2018

well that intresting... The mgig supplies the power, but interface show not connected.

Steve Chapman · ‎07-31-2018

so I now have copies of new ios to install, but how do I do that if the interface wont come up? can I connect a laptop? does the usb port work yet to transfer files?

Leo Laohoo · ‎07-31-2018

"shut"/"no shut" the port of the switch and see if it's made any difference.
What firmware is the switch running on? This looks like a bug on the switch.

Leo Laohoo · ‎07-26-2018

1. Don't worry about PoE for now.
2. What happens if you configure the AP for Mobility Express? What problem(s) do you see?
3. Tell us more about this "link" going down/up.

Steve Chapman · ‎07-27-2018

added the boot up process. We purchased this ap with mobility service installed. I have to end autoinstall to get the link up and down issue. I will upload that info shortly.

Steve Chapman · ‎07-27-2018

ok configured the ap with the following. the up and down messages have stopped, but I still cant get it on the network.
