Cisco Cisco Aironet 1530i Outdoor Access Point Notas de publicación

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.

An access point is unable to obtain IP through the same IOS DHCP server when the access point is 
running on 15.2x. The problem occurs because the Renewal (T1) time dhcp option 58 is larger than 
Rebinding (T2) time dhcp option 59. 

This cli command was used in the previous releases to configure radius servers:

radius-server host {hostname | ip-address} [auth-port port-number] [acct-port port-number] 
[timeout seconds] [retransmit retries] [key string] 

Though this command can still be used, we recommend that you use this new command:

radius server {server-name}[auth-port port-number] [acct-port port-number] [timeout seconds] 
[retransmit retries] [key string]

The following table shows the behavior change:
