Cisco Cisco Aironet 1200 Access Point Notas de publicación

Symbol phones may disconnect and be unable to roam between subnets when the access point passes 
multicast or FTP traffic. If there are no FTP or multicast sessions in progress the Symbol phone operates 
normally and is able to roam between subnets. To work around this issue, limit multicast and FTP traffic 
if you are using Symbol IP phones in a proxy Mobile IP environment.

This section lists resolved and open software issues in VxWorks firmware version 12.04.

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 VxWorks firmware version 12.04:

CSCec22942—Client cannot always obtain a DHCP address across VLANs.

In a system configured with VLANs, the client associates to a VLAN but does not always get an IP 
address.

There is no workaround for this caveat.

CSCdz30285—The Configuring the Cisco Wireless Security Suite application note is incorrect.

The screen capture in section 3.1 of this document shows Add AAA Server, which is incorrect as 
the Aironet device is a client of the ACS, not a server.

Workaround: Call the TAC for setup instructions.

CSCec60688—The access point sometimes drops all client associations and stops communicating 
through both the radio and Ethernet ports.

Workaround: Disable DNS on the access point.

CSCea66593—Access point reboots sporadically because of a protection violation in tRcv_awc0.

Reboots can occur within a 2 to 3 hour period or remain on line for several days and occur based on 
a protection violation of data accessed associated with task tRcv_awc0.

There is no workaround for this caveat.

The following caveats are resolved in VxWorks firmware version 12.04:

CSCea44315—Intermittent AWCO stop/start no longer causes wireless clients to disassociate.

CSCea47390—Access point no longer crashes on task 0x97d2d8 “tThttpd.”
