Limitations and Restrictions

Cisco Aironet 350 Series Bridges Incompatible with 340 Series Bridges

Cisco Aironet 340 and 350 Series Bridges can be connected to the same LAN segments, but they cannot

communicate wirelessly. Although you can disable STP on non-root 350 series bridges, 350 and 340

series bridges are not designed to interoperate. If you use both 340 and 350 series bridges on your

network, make sure the 340 series bridges have radio bridge links only to other 340 series bridges, and

that 350 series bridges have radio bridge links only to other 350 series bridges.

Removing Power During Firmware Update Can Corrupt Radio Firmware

When you update the firmware on an access point or bridge, allow the unit to finish its start-up sequence

before removing power. If you update the firmware and remove power before the unit finishes the

start-up sequence, the radio firmware might be corrupted, making the unit inoperable. If the radio

firmware is corrupted, the radio indicator (the bottom of the three indicators on top of the access point

or bridge) lights steady red, and the following error message appears when the access point or bridge

starts up:

Failed to start driver for port "awc0" (errno=0x006d0002)

If the radio firmware is corrupted, you should try to reset the unit to factory defaults using the :resetall

command in the CLI; see chapter 9 of the Cisco Aironet Access Point Software Configuration Guide for

instructions on resetting the access point. If the unit cannot be reset to defaults, you must return the unit

to Cisco for service.

You can safely remove power after a firmware update when the configuration management pages

reappear in the command-line or web-browser interfaces, or when the three status indicators on top of

the unit complete the following pattern:

When the middle indicator blinks or the top and bottom indicators blink, you can remove power.

EAP Authentication Requires Matching 802.1x Protocol Drafts

Note

This section applies to wireless networks set up to use LEAP. If you do not use LEAP on your wireless

network, you can skip this section.

Wireless client devices use Extensible Authentication Protocol (EAP) to log onto a network and generate

a dynamic, client-specific WEP key for the current logon session. If your wireless network uses WEP

without EAP, client devices use the static WEP keys entered in the Aironet Client Utilities.

If you use Network-EAP authentication on your wireless network, your client devices and access points

must use the same 802.1x protocol draft. For example, if the radio firmware on the client devices that

will associate with an access point is 4.16, the access point should be configured to use Draft 8 of the

Release Notes for Cisco Aironet 340 and 350 Series Access Points and 350 Series Bridges Running Firmware Version 12.01T1

All three indicators are steady green, meaning that the access point is beginning to update the

firmware.

The middle indicator is steady green and the top and bottom indicators are off, indicating that the

access point or bridge is updating the radio firmware.
