Caveats for Cisco IOS Release 12.0

Resolved Caveats—Cisco IOS Release 12.0(11)
• CSCdr22737
The dependent logical unit requester (DLUR) session status remains after you implement INACT
on a local Systems Network Architecture (SNA) major node from virtual telecommunications
access method (VTAM). There is no workaround.
Interfaces and Bridging
• CSCdk45616
Distributed switching is not supported for LAN Emulation (LANE) on a Cisco ATM Lite port
adapter (PA). There is no workaround.
• CSCdp34500
A Cisco 2600 router that is configured with a token ring interface or a Cisco 7200 or 7500 series
router that is configured with a PA-4R-DTR port adapter token ring interface that is running
Advanced Peer-to-Peer Networking (APPN) with Cisco Link Services (CLS)-managed LLC2
logical link control connections might fail host link activation with sense codes 10160007 or
10160022. A router with PA-4R or PA-4R-FDX port adapters is not affected.
Workaround: Enable source route bridging on the affected token ring interface.
• CSCdp79520
Under rare conditions, a Cisco router that is running the rsp-jsv56i-mz (56-bit encryption) software
image on Cisco IOS Release 12.0(8) might experience a bus error if the box is configured for Data
Link Switch over a Token Ring adapter.

There is no workaround.
IP Routing Protocols
• CSCdm44976
IP access lists always permit IP fragments. There is no workaround.
• CSCdp67510
If no interface is specified as part of the offset-list router configuration command, a traceback
might be generated. There is no workaround.
