First of all, sorry for the late replies. Been sick.
@boneyard We replaced the AP with a new one, and a used one (so three AP's tested, all fail at this location)
@The.racking.monkey I'm in Norway, so I really have no idea where I end up when I call ProSupport. If you have technical contacts inside Dell who are good with Aruba gear then I'd be really happy if you could share their contact details in a PM.
I'm noticing something weird with our firewall. It's a Cisco ASA5510, which is in the middle between the AP's and the Controller. When I try to ping an AP from the VLAN where my workstation resides I can't get a reply from the AP. If I do the same from the vlan where the controller resides I do get a reply. When I check the firewall, the following messages pop up:
Denied ICMP type=0, from laddr 10.101.8.15 on interface mgmt-lim to 10.50.10.20: no matching session
mgmt-lim is the interface where the controller resides, not the AP (10.101.18.15). Why would the ICMP reply come from the controller? We're running these AP's in campus mode with bridged VAP's to local MPLS routers.. is the controller acting as a VPN tunnel for the management IP of the AP's?
For some reason the forum doesn't allow me to upload attachments.. I'll try from another browser in a second.
