Symptoms: A router that is configured for BSTUN and BIP may generate an 
“%ALIGN-3-SPURIOUS” memory access error message.

Conditions: This symptom is observed when you change the BSTUN BIP configuration on an 
interface that is processing traffic.

Workaround: Shut down the interface that is configured for BSTUN and BIP before you make any 
configuration changes. 

CSCsa45750

Symptoms: DLSw circuits are established over the same peer connection when there are multiple 
remote peer connections to the same remote MAC address.

Conditions: This symptom is observed when DLSw load-balancing is configured and when there are 
multiple peers that have the dlsw icanreach mac-address mac-addr command enabled with the 
same remote MAC address for the mac-addr argument.

Workaround: Bounce the DLSw peer connection either by entering the dlsw disable command or 
by removing and reconfiguring the DLSw remote peer statement.

Further Problem Description: You can verify that the symptom occurs when the output of the show 
dlsw reachability command does not show the remote peer with the MAC address displayed as 
UNCONFIRMED or FOUND.

Symptoms: A VC that is configured on an ATM PA-A3 port adapter may stop receiving traffic.

Conditions: This symptom is observed on a Cisco 7x00 router that is configured with an ATM 
PA-A3 port adapter when the default MTU is changed to a higher value.

Workaround: Enter the shutdown interface configuration command followed by the no shutdown 
interface configuration command on the subinterface on which the VC is configured.

Symptoms: When you activate a serial interface on a PA-MC-8TE1+ port adapter that is installed in 
a VIP, dCEF may be disabled on the slot in which the PA is installed (in this example, in slot 3) and 
the following error message is generated:

%FIB-3-FIBDISABLE: Fatal error, slot 3: IPC Failure: timeout

The output of the show controller vip 3 logging command may time out, indicating problems with 
IPC.

The failure may cause additional error messages or may cause the VIP to reset, affecting all port 
adapters that are installed in the VIP.

Conditions: This symptom is observed on a Cisco 7500 series with a faulty PA-MC-8TE1+ port 
adapter that is installed in a VIP.

Workaround: There is no workaround. This fix for this caveat eases the detection of a faulty port 
adapter (see below).
