Cisco Discovery Protocol Re-Enabled for Individual Interfaces on Reboot

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

Open Caveats
The following caveats have not been resolved for firmware version 11.50T:
•
CSCdy03375—The Carrier Test and Antenna Alignment radio diagnostic tools are available only
for the access point’s 2.4-GHz radio.
for the access point’s 2.4-GHz radio.
•
CSCdy03381—One access point radio sometimes fails to restart after a warm reset. Workaround:
Perform a cold reboot of the access point if one of the radios does not restart.

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.

•
CSCdy10787—The access point aborts any configuration containing an unknown MIB variable.
When an access point receives a configuration from another access point that is running a newer
firmware version than the receiving access point, the receiving access point aborts the configuration
if it encounters a MIB variable that it does not recognize. Workaround: Upgrade access points to the
same firmware version before distributing configurations.

•
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.

Encryption page.
