Resolved Caveats—Cisco IOS Release 12.0(2)
• CSCdk53320
An APPN router might reload with the following traceback error in the show stacks log capture:
%APPN-3-Error: INVALID LPID 61318C81 Pid 0020100C IPSname 1

• CSCdk54077
An APPN router might reload with a SegV exception in psp00 after the following message is
displayed in a rare race condition:
%APPN-6-APPNSENDMSG: APPN Allocate 613D1F8C to NETA.MVS1 timed out for TP “001.
System was restarted by error - a SegV exception, PC 0x606AE270
• CSCdk54687
An APPN router enlarges its LFSID table from a small model to a large model if more than 12
SIDLs are active for a specific SIDH. The large LFSID table requires substantially more memory.
The resolution to CSCdk54687 increases the number of entries in the small LFSID table to the
maximum number of SIDLs that fit into this table. This requires no additional memory per link but
increases the number of SIDLs supported in the small LFSID table. Thus, in customer networks
that typically support 17 LUs/PU, the APPN router might use significantly less memory.
• CSCdk55765
DLUR routers incorrectly update the max-BTU-size for links to Type 2.1 nodes.
Interfaces and Bridging
• CSCdj43445
The FDDI port adapter now has a software address filter at the VIP level to filter out unwanted
multicast packets. This helps performance and also unnecessary entries in NetFlow tables.
• CSCdj85213
A router coded as a primary SDLC interface might send an erroneous frame, causing the secondary
device to send a FRMR.
• CSCdk01309
When a 100-Mbps interface on the Cisco 3600 series, configured for ISL encapsulation, is
modified, the interface might cause carrier loss and ISL trunk flapping.
• CSCdk10225
When you attach some routers, such as a Cisco 2500 series or Cisco 4000 series router, directly to
a switch that is configured for autosense, the switch detects the port as being full-duplex, but the
routers only support half-duplex. The Token Ring interface on the router shows up/up but only
broadcast traffic passes. On the switch you see line errors incrementing at a very high rate. A ping
issued from the router to a local device on the ring with the switch fails.
Workaround: Manually set the switch to half-duplex.
