I've had a second deployment failure with Cisco AIR-AP-1832i WLC/APs running Mobility Express. The issue is that I can't seem to get off VLAN1, or I suppose it would be more accurate to say the native VLAN.
Scenario is that I have two WLANs as follows:
WLAN1: SSID: Corporate VLAN: 1
WLAN2: SSID: Corporate-Guest VLAN: 100
I can connect to either WLAN/SSID successfully with a client. But only the Corporate WLAN gets me to the proper DHCP server and gives me the ability to pass traffic successfully. Connecting to Guest fails to locate a DHCP server, so I get an APIPA address and nothing works. Configuring a static IP on the proper subnet does not allow traffic to pass.
In this deployment, I am using a Cisco Catalyst 2960 switch with the WLC/AP port being a trunk with dot1q. Here's the best part: I replaced a Cisco WAP321 (yeah, small business) AP with the same WLAN/VLAN/SSID configuration that was connected to the very same switch port. The WAP321 handled the two SSIDs and VLANs perfectly. No issues whatsoever connecting, getting IP addresses on either network or passing traffic. I made no changes to the switch configuration.
The previous failed deployment I had was a bit different in symptoms: The VLAN configuration was the same, a corporate network and guest network, corporate was on VLAN1 and Guest was VLAN 10. This time, I could connect to either SSID, but I would always get an IP address from the DHCP server on VLAN 1. It's like the VLAN 10 tag was completely ignored. I had a TAC case on that one that became a nightmare when Cisco could find nothing wrong with my configuration of the WLC/AP, switch, or ASA (DHCP server for VLAN 10). They could offer no explanation, even though I provided a pcap from the WLC's switchport (mirrored to my laptop running Wireshark) to TAC. I opted to RMA the 1832s in that case after TAC failed to resolve the situation. I haven't deployed the new APs (different vendor) yet.
Anyway, my question to anyone familiar with these 1832i series units is, what am I missing, or is there a known problem with these things? I don't have these issues with real Cisco WLCs (2504 for example) or even the small business line, although Cisco's new crop is terrible and I won't buy them.
By the way, these last 1832i's shipped with 8.4.100.
