Cisco Cisco IOS Software Release 12.4(23)

frame-relay map ip ip-address dlci payload-compression frf9 stac

Further Problem Description: We do not recommend process-switching in combination with 
software payload compression because it is not possible to provide latency guarantees. 

CSCin67809

Symptoms: CEF, dCEF, and fast-switching counters are not accurate on outbound serial E1 or T1 
interfaces.

Conditions: This symptom is observed on a Cisco 7200 series when CEF, dCEF, and fast-switching 
are enabled on a serial E1 or T1 interface.

Workaround: There is no workaround. 

CSCin75573

Symptoms: When you perform an OIR of a PA-MC-8TE1+ or PA-MC-8E1 port adapter, the 
following error message and traceback may be generated:

%ALIGN-3-SPURIOUS: Spurious memory access made at 0x60379D34 reading 0xD8 % 

ALIGN-3-TRACE: -Traceback= 60379D34 604F1CFC 60BD0664 6032B93C 6039A0CC 6010A908 

6032AA7C 6032EBAC

Conditions: This symptom is observed on a Cisco router when the port adapter is configured for 
QOS on an egress serial interface and traffic is flowing through this interface.

Workaround: There is no workaround. 

CSCin89590

This caveat consists of two symptoms, two conditions, and two workarounds:

Symptom 1: On the RSP console, the link status of a Fast Ethernet (FE) interface is shown as 
UP/DOWN, but on the VIP console, the link status of the same interface is shown as UP/UP.

Condition 1: This symptom is observed on a Cisco 7500 series until a packet that is received on 
the FE interface reaches the RSP.

Workaround 1: There is no workaround.

Symptom 2: An FE interface is in the UP/UP state but the output of the show ip route command 
does not show any routes through the interface.

Condition 1: This symptom is observed on a Cisco 7500 series.

Workaround 2: Enter the clear ip route command on the affected FE interface. Note that doing 
so causes all routes to be relearned. 

CSCsa46510

Symptoms: When you enter the microcode reload command, an error message similar to the 
following and a traceback may be generated:

RSP-3-RESTART: interface Serial3/0/1/4:0, not transmitting 

-Traceback= 404436B4 4044DE10

Conditions: This symptom is observed on a Cisco 7500 that is configured with a E1, T1, E3, or T3 
port adapter.

Workaround: There is no workaround. 

CSCsa83897

Symptoms: A channelized T3 port adapter cannot detect C-bit errors and does not shut down after 
continuous C-bit errors.

Conditions: This symptom is observed on a Cisco 7200 series that is configured with a channelized 
T3 port adapter.
