Rebooting AP275 and Uplink VLAN?

I opened a TAC case for a constantly rebooting AP275. It cycles every 11 or 12 minutes - show an ID flag then appears to reboot. Lather, rinse, repeat.

 

TAC wants me to attach a console cable. Which is a pain, because this is up a pole in a public area.

 

While I am waiting for an opportunity to grab it, I did the "what's different about this one?" game. I have 80 275's operating well.

 

So it turns out, it seems, that Uplink VLAN may be the culprit. I have all of my WiFi gear communicating with the controller across VLAN114. The controller hands out DHCP for this VLAN, and the misbehaving one has been getting a proper assignment. But (perhaps in an effort to fix a problem, I forget) this AP is set to Uplink VLAN 114. My other AP's are set to Uplink = 0.

 

I went into the switch port for this AP and untagged it to VLAN 1, and it has been up and not rebooting for a few hours. If has an IP address off of my default VLAN, so it's not a permanent fix.

 

So my question is, what should Uplink VLAN be set to, when the switch you are connecting to has the port untagged for VLAN 114?

Do not set it.

OK, so I learned that the hard way.

 

An Uplink VLAN does indeed cause the rebooting behviour I was experiencing. Weird but true,
