Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(27)S
• CSCdz72292
Symptoms: After a few weeks of normal operation, the interface on a Cisco PA- MC-8E1 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
Conditions: This symptom is observed on a Cisco router that is configured with a PA-MC-8E1
interface.
Workaround: There is no workaround.
• CSCdz80580
Symptoms: A DPT-OC-12 port adapter (PA-SRP) may stop transmitting packets.
Conditions: This symptom is observed on a Cisco uBR7200 series when a packet that is smaller than
8 bytes is transmitted on the PA-SRP.
Workaround: Perform an online insertion and removal (OIR) of the PA-SRP.
• CSCdz83304
Symptoms: A T3 link on a 4-port channelized OC-3 line card may not come up under Synchronous
Digital Hierarchy (SDH) framing.
Conditions: This symptom is observed on a Cisco 10000 series when the 4-port channelized OC-3
line card interoperates with third-party vendor test equipment.
Workaround: Enter the shutdown controller configuration command followed by the no shutdown
controller configuration command on the AU-3 controller that contains the T3 link.
