Cisco Cisco Aironet 350 Access Points Release Notes

is passed. Error messages (about one per packet) print on repeater (B)'s console to the effect that a device 
that has associated with WEP tried to pass an unencrypted packet. 

If WEP is disabled, this topology functions properly. If the firmware is set to 11.10T on all units, no 
WEP and Static WEP also function properly.

Workaround: No workaround currently exists for firmware versions greater than 11.10T. Customers 
with a nested repeater topology should stay with access point and bridge firmware 11.10T.

CSCdx22660—Hot Standby does not work with LEAP enabled. Hot standby will work when an 
SSID or a WEP key is activated. However when LEAP is enabled, the hot standby process starts and 
then fails. When the failure occurs , the access point’s radio is disabled, requiring a restart to bring 
it back up.

Workaround: Current LEAP support for the hot standby requires the following action:
1. Configure the standby unit's user name and password.
2. Do NOT enable Require EAP for Open and Shared Authentication type.

CSCdy58522--Access point or bridge loses portions of configuration when upgrading firmware 
from 11.21 to 11.23T. If an access point or bridge configuration contains host names (ftp.cisco.com, 
for example) instead of IP addresses in one or more configuration fields, the access point or bridge 
might lose some or all of its configuration when you upgrade the firmware from 11.21 to 11.23T. 
Workaround: Use IP addresses instead of host names in all configuration fields when upgrading 
from 11.21 to 11.23T.

The following caveats have been resolved in firmware version 11.23T:

Resolved: CSCdx03420—The default for the Require use of Radio Firmware X.XX setting on the 
AP/Root Radio Advanced page is yes instead of no. This setting prevents the AP radio from going 
down when loading firmware.

Resolved: CSCdx03869—Non-initial fragments (that only have the IP header info, but no UDP port 
info) are no longer blocked by IP port filters defined on the access point.

Resolved: CSCdx07970—defaults can now be restored on the CLI’s Ethernet Protocol Filters and 
Root Radio Protocol Filters pages.

Resolved: CSCdx11703—The frequency of hot standby packets has been decreased so that they do 
not flood the network.

Resolved: CSCdu13008—DNS lookup timeout no longer permanently disables DNS.

Resolved: CSCdw13878—The standby access point no longer fails when hot standby is configured 
with SNMP.

Resolved: CSCdw16742—Broadcast key rotation now works with repeater access points and 
non-root bridges.

Resolved: CSCdx19068—Roaming clients are no longer permanently locked out by limited 
concurrent session configuration on the ACS server.

Resolved: CSCdx19118—The access point or bridge no longer reboots when more than 23 
workgroup bridges are associated to it and certain settings are changed.

Resolved: CSCdx19270—The access point no longer reboots when the Classify Workgroup Bridges 
as Network Infrastructure setting is set to yes on an access point or bridge with more than 23 
workgroup bridges associated. The root cause of this defect is the same as CSCdx19118.
