Core Issue
Serial numbers do not show up on any of the BR 350 or AP 350s that you have by commands.
Resolution
The 350 Series APs and bridges that run VxWorks do not display the serial number in software. The only way to identify the serial number on these units is to physically inspect the label on the hardware itself. The serial number for the IOS AP's such as 1100 and 1200 can be found using the software.
Refer to Cisco Aironet Access Point FAQ for more information about the access point and bridge.
