Cisco Cisco Aironet 350 Access Points 릴리즈 노트

The Cisco Discovery Protocol (CDP) feature is enabled by default, and CDP is enabled for each of the 
access point’s or bridge’s individual interfaces by default. However, if you disable CDP for one of the 
individual interfaces, the access point or bridge re-enables CDP for that interface when it reboots. If you 
disable CDP completely, the access point or bridge does not re-enable CDP on reboot.

This section lists open and resolved software issues in firmware version 11.21.

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 11.21:

CSCdx03420—Radio might shut down when upgrading firmware.

When you upgrade access point or bridge firmware, the unit’s radio might shut down. Workaround: 
Select yes for the Require use of Radio Firmware X.XX setting on the AP/Root Radio Advanced page 
and follow the upgrade steps again.

CSCdx07970—Cannot restore defaults on the CLI’s Ethernet Protocol Filters and Root Radio 
Protocol Filters pages.

The Restore Defaults feature does not work on the CLI’s Ethernet Protocol Filters and Root Radio 
Protocol Filters. Workaround: Use the web-browser interface to restore defaults on the Ethernet 
Protocol Filters and Root Radio Protocol Filters pages.

CSCdx11703—Hot standby packets can flood the network.

Each time a standby access point checks the status of the access point it is monitoring, it sends 11 
probe packets. If you have several access points on your network set up for hot standby, the probe 
packets can overload your network. Workaround: Enter a higher value for the Polling Frequency 
setting on the Hot Standby page. For example, instead of polling the monitored access point every 
few seconds, enter 600 in the Polling Frequency entry field to poll the monitored access point every 
ten minutes.

CSCdw13878—Setting up hot standby when monitored access point’s radio is disabled locks up 
standby access point.

If the radio is disabled on the monitored access point when you set up the standby access point, the 
standby access point reports an initialization failure and must be rebooted. Workaround: Make sure 
the monitored access point’s radio is working when you set up the standby access point.
