Resolved Caveats—Cisco IOS Release 12.0(2)
• CSCdk51491
If a router is configured to support Layer 3 switching with in and out access filters on the HSSI and
Frame Relay IETF encapsulation, subsequently trying to configure SMDS encapsulation causes the
router to fail.
• CSCdk53176
Issuing the no traffic-shape group command causes the router to fail.
• CSCdk55115
V.120 users can now correctly configure autocommand ppp negotiate under vtys.
• CSCdk57493
Starting with Cisco IOS Release 11.3(5.1)T, a reverse-Telnet connection that receives a Telnet
BREAK sequence fails to send an EIA/TIA-232 (RS232) BREAK to the associated async line. An
outgoing Telnet connection that receives a Telnet BREAK sequence also fails to output a BREAK
condition; this instance of the problem has existed for quite some time.
• CSCdk64322
RSP range registers set correctly to enforce the 2-MB limit on MEMD access.
EXEC and Configuration Parser
• CSCdk33946
The router might fail while editing the command line under low memory conditions.
• CSCdk52457
Using ctrl-x to terminate a Telnet connection might cause the router to fail.
IBM Connectivity
• CSCdk10830
An APPN router might display a single console CP-CP session. This CP-CP session cannot be
deactivated by issuing the appn stop cp-cp command.
Workaround: Stopping the APPN link clears this problem.
• CSCdk12302
While control units are being removed by router or end device activity, issuing the show bsc
command might cause the router to fail.
• CSCdk25935
While DLSw with FST encapsulation is configured on a router, the following error message with
traceback might appear:
00:39:38: %SYS-2-INPUTQ: INPUTQ set, but no IDB, ptr=ADDD9C -Traceback= 148D3A 572A 4DF4
110064 17DAA2 17B0DA 14CC 10005B4 10047DA
• CSCdk36264
If DLSw is configured to use TCP as the transport, and if the following conditions are met, a TCP
packet coming from the peer could get stuck in the TCP buffers of the router. A TCP packet might
get stuck when there are no keepalives between the peers (like in an ISDN connection), there is no
