Caveats for Cisco IOS Release 12.0

Resolved Caveats—Cisco IOS Release 12.0(10)
DECnet
• CSCdp50978
A Cisco router might reload if it pings a DECnet address across an ISDN BRI connection. Pinging
IP continues to work, as does DECnet routing. There is no workaround.
IBM Connectivity
• CSCdm66552
A Cisco 2500 series router might suddenly stop receiving or not forward packet frames while
transferring files over data-link switching plus (DLSw+) link using Fast Sequenced Transport
(FST) encapsulation. This situation causes the NetBios session to disconnect. There is no
workaround.
• CSCdp09939
A Cisco router might experience a bus error as a result of a timing error. There is no workaround.
• CSCdp43233
A Cisco 7500 series router that is running a Cisco IOS release higher than the Cisco IOS Release
12.0(3c) might experience a situation where attached Network Basic Input/Output System
(NetBIOS) PCs are not reaching the Ethernet-attached NetBIOS server. When this situation occurs,
the router sends an incorrect LAN Emulation Address Resolution Protocol (LE_ARP) request, and
is unable to resolve the route descriptor for the local LANE cloud and the Token Ring behind the
Token Ring switch. A Logical Link Control, type 2 (llc2) frame out of the data-link switching
(DLSw) cloud directed to the PC will trigger a LANE LE_ARP lookup on the router for the wrong
route descriptor. As a result, the LANE data direct virtual channel connection (VCC) is only used
in one direction from the Token Ring switch to NetBIOS PCs, and the NetBIOS connection pauses
indefinitely. There is no workaround.
• CSCdp59004
A Cisco router that is running Advanced Peer-to-Peer Networking (APPN) with High-Performance
Routing (HPR) enabled might leak some processor memory when establishing Routing Table
Protocol (RTP) connections. These leaks may be seen in cell pools 0, 1, and 2 of APPN Memory
Partition 0. There is no workaround.
• CSCdp63998
A Cisco router that is running Advanced Peer-to-Peer Networking (APPN) might reload after the
operator enters the show appn dlur-pu host-pu command. There is no workaround.
• CSCdp81656
A Cisco router that is running Advanced Peer-to-Peer Networking (APPN) High-Performance
Routing (HPR) might reload when it receives a Bind Route Request Unit. There is no workaround.
• CSCdp83343
A Cisco Advanced Peer-to-Peer Networking (APPN) router might reload because of a bus error
while attempting to allocate an input/output (I/O) memory buffer. The router exhibits the following
error message:
Memory allocation of 788 bytes failed from 0x602BE4C0, pool I/O, alignment 32 -Process=
“cswebtsk”, ipl= 4, pid= 67
There is no workaround.
