I don't see a default gateway, so are you trying to access the AP from the same subnet? Is this an old or a new MSR? Have you connected your laptop directly to it through a power injector and then can you see 212? If you change the port to access on 212, can you then see it?
Here is what my lab setup looks like, SSID carries on 150, management is on 100.
interface gigabit-ethernet 0
mode gateway
switchport trunk allowed-vlan 100,150
switchport trunk native vlan 100
interface loopback 0
ip address from-mac
router-id
interface vlan 1
management
mtu 1500
interface vlan 100
ip address 192.168.100.211/24
mtu 1500
ip route 0.0.0.0/0 192.168.100.254
local-ip 192.168.216.1/24
