Open Caveats
The following caveats have not been resolved for firmware version 11.07a:
•
Protocol filter settings sometimes revert to defaults during filter setup (CSCdu02040).
When you add a new protocol filter set, you can set the filter’s default disposition and time-to-live
on the first filter configuration page. You add specific protocols to the filter set on subsequent pages.
If you change the default disposition or default time to live values from the defaults, these values
revert to default settings after you add specific protocols to complete the filter setup. Make sure the
default disposition and time-to-live values are correct before you apply the filter set.

•
IP Port filters do not block pings (CSCdu05324).
Table B-3 in Appendix B of the Cisco Aironet Access Point Software Configuration Guide lists PING
as the additional identifier for the echo IP Port filter entry. However, the echo entry does not block
standard pings. To block standard pings, set up an IP Protocol filter to block ICMP.

•
Cannot access workgroup bridges associated with access point (CSCdu10993).
When a workgroup bridge (WGB34x or WGB352) is associated to an access point, you cannot
access the WGB console menus or ping the WGB from a station on the wired LAN connected to the
access point’s Ethernet port. However, you can access the WGB from any client device connected
to the WGB's Ethernet port and from any client device associated to the access point that is
associated to the WGB. Radio traffic between the access point and the WGB is not affected.

Access point ignores vendor specific options from DHCP servers (CSCdu19500).
Access points ignore the vendor specific option (VSO) sent from DHCP servers inresponse to the
access point’s vendor class identifier, also called a DHCP identifier in the access point’s web
browser interface and CLI.

Continuous reboot caused by exception error on access points running firmware version 11.07a
(CSCdv20709).
(CSCdv20709).
Access points running firmware version 11.07a continuously reboot when the following error
occurs:
occurs:
instruction access
Exception next instruction access: 0xcccc0000
Machine Status Register: 0x08209032
Condition Register: 0x48000040
Task: 0xa1b960 “tProtoCDP”
The error occurs when a CDP-unaware device, such as a hub that does not support CDP, forwards
CDP messages containing the power consumption TLV from one access point to another. The access
point receiving the forwarded CDP message reboots.
