Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• After a few weeks of normal operation, an interface on a PA- MC-8E1 port adapter begins flapping
and finally pauses with the output queue stuck as follows:
Serial1/1:1 is up, line protocol is up
Encapsulation HDLC, crc 16, Data non-inverted
Keepalive set (120 sec)
Last input 00:00:03, output 04:14:23, output hang never
Last clearing of "show interface" counters never
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 21952
Queueing strategy: weighted fair
Output queue: 30/4000/64/21855 (size/max total/threshold/drops)
30 second input rate 0 bits/sec, 0 packets/sec
30 second output rate 0 bits/sec, 0 packets/sec
43903807 packets input, 3646461183 bytes, 0 no buffer
Received 0 broadcasts, 321 runts, 0 giants, 0 throttles
5160 input errors, 4 CRC, 0 frame, 0 overrun, 0 ignored, 2945 abort
42026998 packets output, 2185017012 bytes, 0 underruns
0 output errors, 0 collisions, 0 interface resets 0 output buffer failures,
0 output buffers swapped out 31 carrier transitions
no alarm present
Timeslot(s) Used:1-31, subrate: 64Kb/s, transmit delay is 0 flags
The following traceback is observed in the log:
%LINK-4-TOOBIG: Interface Serial60:1, Output packet size of 1526 bytes too big
Traceback= 0x604007F8 0x604A927C 0x6084E4D4 0x6057425C 0x60CE921C 0x60CE55EC
%LINK-4-TOOBIG: Interface Serial20:1, Output packet size of 1526 bytes too big
Traceback= 0x604007F8 0x604A927C 0x6084E4D4 0x6057425C 0x60CE921C 0x60CE55EC
This problem is resolved in Release 12.1(20)E. (CSCdz72292)
• All high-capacity counters remain at 0 for FlexWAN module POS interfaces. This problem is
resolved in Release 12.1(20)E. (CSCdz46845)
• Connections cannot be made to users behind ATM PVCs on a FlexWAN module. This problem is
resolved in Release 12.1(20)E. (CSCdz61962)
• In a system installed with a FlexWAN and a PA-A3 ATM port adapter, the ATM interface may stay
down after you enter a shutdown command followed immediately by a no shutdown command.
This problem is resolved in Release 12.1(20)E. (CSCdy23751, CSCdw65799)
• With a redundant Supervisor Engine 2, crypto images do not recognize FlexWAN modules at bootup
when RPR is configured. This problem is resolved in Release 12.1(20)E. (CSCeb47607)
• With dial-up networking (DUN) configured, the IP Control Protocol (IPCP) times out on a link
control protocol (LCP) negotiation. This problem is resolved in Release 12.1(20)E. (CSCea51540)
• ATM subinterface traffic might be incorrectly dropped. This problem is resolved in
Release 12.1(20)E. (CSCea81118
