Cisco Cisco Aironet 350 Access Points

When backbone connectivity is lost on an access point running version 12.01T, the device switches to 
repeater mode. Switch to Repeater mode is the default setting for this condition. Therefore, if the access 
point’s role in your network is not a repeater access point, make sure you connect it to your wired 
network before booting it up. If you do not connect the access point to your network, it switches to the 
repeater mode when it fails to detect the presence of an Ethernet connection. When this occurs, wireless 
client devices are unable to connect and you cannot correct the problem using a wireless client. The only 
way you can change the configuration is through a serial connection using the access point’s command 
line interface.

This section lists open and resolved software issues in firmware version 12.01T.

If you are a registered Cisco user, you can use the Cisco TAC Software Bug Toolkit, which consists of 
three tools (Bug Navigator, Bug Watcher, and Search by Bug ID Number) that help you identify existing 
bugs (or caveats) in Cisco software products.

The following caveats have not been resolved for firmware version 12.01T:

CSCdz04708—Early 340 series access points are incompatible with VLAN tagging.

Early versions of the 340 series access point are able to set up VLANs, but clients on non-native 
VLANs will be unable to transmit and receive large packets. The reason for this is because early 340 
series access points were limited to a maximum packet data length of 1500 bytes.

You can identify an affected access point by browsing to the Ethernet Identification page and 
checking the Maximum Packet Data Length parameter. If it is 1500, the failure will occur. 

Possible workaround—If you have an early 340 series access point on your network, you can 
eliminate the problem by setting the Maximum Packet Data Length parameter for all other devices 
to 1400 bytes.

CSCin18914—IP release or renew not occurring with EAP-TLS+MIC+KH+BWR.

When a client associates with EAP-TLS + 40/128 bit broadcast key + MIC +Keyhash + Broadcast 
WEP key rotation (10sec), and IP DHCP release and renew commands are issued, the client releases 
the IP address, never receives it again, and remains EAP authenticated. A ping from the access point 
to the client appears to succeed, but does not reveal an IP address. The access point association table 
shows the IP address for the client as 0.0.0.0.
