Cisco Cisco Aironet 1200 Access Point 릴리즈 노트

CSCdy20169—When a 1200 series access point boots, it sometimes displays this warning:

(Warning) Routine "pktRouterRcvRtn" is unable to Take the forwardTbl Guard semaphore

You can ignore this message.

CSCdy27831—When you set the default Unicast Address Filter to disallowed, you must reboot the 
access point for the setting to take effect.

CSCdy29556—Symbol IP phone continuously associates and authenticates to an access point 
configured with multiple VLANs.

When a Symbol IP phone is associated to a VoIP VLAN (Symbol extensions enabled), the phone 
associates to the access point and is authenticated approximately every 2 seconds. The Symbol 
phone shows a “No Network” error every 1 to 2 minutes.

It also appears that Symbol phones do not work well when using a non-primary SSID. It is possible 
that the phone does not perform an active probe and therefore does not detect information about the 
SSID it associated with in the beacon, causing it to reassociate and re-authenticate.
There is no workaround for this caveat

.

CSCdz43069—Symbol phone not working when multicast or FTP traffic is passed. 

If an FTP or multicast session is in progress during a Symbol phone session, the phone call may be 
dropped and the phone may be unable to roam between subnets. If there are no FTP or multicast 
sessions in progress, the Symbol phone operates normally and is able to roam between subnets.

Workaround: Limit multicast and FTP traffic if using Symbol phones in a proxy Mobile IP 
environment.

CSCdz48575—Default lost Ethernet action not appropriate.

See the 

 for a complete description of this 

caveat.

CSCdz50218—Access point does not update home or foreign agent status when advertisement flags 
change. 

When a local home or foreign agent is disabled on the router, the access point does not detect the 
change from the the advertisement flags it receives. The access point continues to list the agent 
addresses on the Statistics page.

Workaround: Disable and then enable proxy Mobile IP.

CSCdz58192—Root bridges with LEAP enabled on the native VLAN must have the security setting 
matching that set on the Advanced Radio Setup page. If the settings do not match, the bridge link 
will go down temporarily whenever an infrastructure device authenticates.

CSCdy73695—When a repeater access point receives packets from a root access point while the 
repeater is attempting to associate, the repeater sometimes displays this error:

00:00:10 (Warning): Station <Root MAC address> Associated with Encryption, then 

attempted to send an Unencrypted packet to <Repeater MAC address> (length 74)

The error occurs when WEP is not enabled on either the root or the repeater. When an association 
response is received by the repeater, it no longer displays the error message and is able to 
successfully pass data. However, if a significant amount of traffic, such as multicast traffic, is being 
transmitted by the root access point while the repeater is attempting to associate, the repeater may 
miss the association response from the root access point and never fully associate. In this case, the
