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.

CSCin18914—IP release or renew not occurring with EAP-TLS+MIC+KH+BWR.

When a client associates with EAP-TLS + 40/128 bit broadcast key + MIC +Keyhash + Broadcast 
WEP key rotation (10sec), and IP DHCP release or renew commands are issued, the client releases 
the IP address, never receives it again, and remains EAP authenticated. A ping from the access point 
to the client appears to be successful, but does not reveal an IP address. The access point association 
table shows the IP address for the client as 0.0.0.0.

CSCdz32333—Repeater bridge link intermittent with LEAP client on non-native VLAN. 

An intermittent drop occurs in a bridge link between a root bridge and a non-root bridge acting as a 
repeater or non-root device. The drop occurs when a client LEAP authenticates and associates with 
the non-root bridge that is acting as a repeater or non-root device. When the client associates to an 
SSID that is mapped to the non-native VLAN on the non-root bridge, it subsequently brings down 
the bridge link between the root and the non-root that is LEAP authenticated as well. The condition 
is intermittent and does not seem to occur if the VLAN is not enabled or if the client is associated 
to the root bridge or is using open or WEP authentication to the non-root bridge. 

There is no workaround for this caveat.

CSCdy76093—Proxy Mobile IP with multiple authoritative access points continuously sends 
update packets. 

See the 

 for details and procedures 

to correct this problem.

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.
