Resolved Caveats—Cisco IOS Release 12.0(10)
TN3270
• CSCdp50276
A TN3270 client on a Cisco access server might erroneously leave the keyboard in a locked state
causing all keyboard input to be rejected until you press the master_reset keypress. This situation
occurs when an application sends write-structured field commands with the keyboard-restore
indicator on the associated write-control character. There is no workaround.
Wide-Area Networking
• CSCdp05882
A Cisco 7200 VXR router might reload with a bus error because the packet-by-packet compression
code is being passed packets that contain particles. There is no workaround.
• CSCdp35206
A Cisco 7200 series router that is running Cisco IOS Release 12.0(7) might reload with a bus error
at PC 0x60584578, address 0xD0D0D51. There is no workaround.
• CSCdp40411
The frame-relay de-group 1 local-dlci interface configuration command might disappear from the
running configuration and stop working for the referenced data-link connection identifier (DLCI)
if you configure the frame-relay inverse-arp interface configuration command and the
corresponding permanent virtual connection (PVC) status changes to Inactive or Deleted.
Workaround: Use the static frame-relay map interface configuration command and reference the
same DLCI that is used for the frame-relay de-group 1 local-dlci interface configuration
command.
• CSCdp41653
A Cisco router that is running Cisco IOS Release 12.0 or later releases might reload because of a
bus error at the symbol dialer_clear_map. There is no workaround.
• CSCdp51357
When X.25 over TCP (XOT) connects X.25 links that are configured for module 128, the packet
assembler/disassembler (PAD) session will pause indefinitely. In this situation, entering the show
x25 vc EXEC command will return a “Window is closed” message. There is no workaround.
• CSCdp59874
Timer data structures used by the dialer component might become corrupted. The corruption might
occur because of operator-initiated actions that involve the removal of the dialer function on an
interface. Examples of these actions would be configuring leased-line BRI, or entering the no
dialer in-band interface configuration command. The symptom might not occur for days or weeks
after the operator action that caused it. Due to this condition, these actions should be avoided. There
is no workaround.
• CSCdp60088
On a Cisco router with dialer profiles, dialer load-threshold, and no multilink, an overload call
might not be done even though the load threshold is exceeded. This situation occurs when an
incoming call is received with a particular caller ID but there is no dialer string configured with the
same phone number.
Workaround: Initiate first and overload calls from the same router.
