Caveats
Autonomous Ap Will Treat The Sub-interface Tied To Bridge-group 1 As The
Native Vlan
Native Vlan
When using a configuration on an autonomous AP where there is no native VLAN defined, each
interface is being dot1q tagged, communication will fail after upgrading to 15.2(2)JA or later. It appears
that the configuration is still correct after the upgrade, but the AP sends the untagged frames for
bridge-group 1, even though the encapsulation is not defined as native. The autonomous AP will treat
the sub-interface tied to bridge-group 1 as the native VLAN, even if it is not defined with the native
keyword: "encapsulation dot1 <vlan> native". The VLAN associated with bridge-group 1 must be set to
native on the connecting switchport configuration

The workaround for this is to configure VLAN 100 as the native VLAN on the connected switchport
trunk, even though the encapsulation is not specified as native on the AP.
trunk, even though the encapsulation is not specified as native on the AP.
IP Routing Enabled By Default
IP routing is enabled by default in 15.2(2)JB. This default configuration will render ip default-gateway
statements inoperable. The work around is to disable ip routing globally (config t, no ip routing), or
configure a default route instead of a default-gateway (e.g. config t, ip route 0.0.0.0 0.0.0.0
<default-gateway> ).

DHCP Failure When Access Point Renewal Time Is Greater Than Rebind Time
An access point is unable to obtain IP via same IOS DHCP server when the access point is running on
15.2x and the WLC has been upgraded from 7.2 to 7.3 or 7.4. The problem occurs because the Renewal
(T1) time dhcp option 58 is larger than Rebinding (T2) time dhcp option 59.
