Resolved Caveats—Cisco IOS Release 12.0(3)
Resolved Caveats—Cisco IOS Release 12.0(3)
All the caveats listed in this section are resolved in Cisco IOS Release 12.0(3). This section describes
severity 1 and 2 caveats and select severity 3 caveats.
Access Server
• CSCdk66309
When the pri configuration command is issued for a T1/E1 controller, the following message might
appear on the console:
SYS-3-MGDTIMER
There is no workaround.
• CSCdk69102
A Cisco AS5800 access server that runs Cisco IOS Release 11.3(6.1)AA or a more recent release
might experience a system reload following a modem pool download. This only affects the
downloading of nondefault firmware and is only experienced a small percentage of the time. This
condition might also arise when the access server runs Cisco IOS Release 12.0(1.5) or a more
recent release. There is no workaround.
Basic System Services
• CSCdj85843
VIP cards do not have an accurate sense of time. NetFlow exports, for example, are not
synchronized. There is no workaround.
• CSCdk24870
IP trigger authentication does not work with Multilink Point-to-Point Protocol (MLPPP). IP trigger
authentication only works with a single channel. There is no workaround.
• CSCdk38629
When voice-encap is configured on a Frame Relay or Cisco HDLC, all fancy queuing is disabled
and only FCFS is allowed.
Workaround: The new [no] frag-pre-queuing CLI command has been added to the interface with
Frame Relay encapsulation that users can select if queuing is performed after fragmentation. The
default setup is frag-pre-queuing, which allows only first come first served (FCFS) queuing on the
interface level. With the [no] frag-pre-queuing command, the user can configure weighted fair
queuing (WFQ), custom queuing (CQ), or priority queuing (PQ) on the interface level so that all
fancy queuing is supported with voice-encap. After the [no] frag-pre-queuing command is issued,
the interface queue is not changed. The user needs to explicitly specify WFQ, CQ, or PQ if such
fancy queuing is desired. For HDLC encapsulation, fragmentation is moved to after queuing. For
HDLC, all fancy queues are allowed with this caveat fix.
• CSCdk46007
When a Cisco MC3810 multiservice access concentrator that has a large number of Frame Relay
PVCs is upgraded to Cisco IOS Release 11.3(1)MA5 or later, the console might display memory
allocation failures because of an insufficient big buffer pool of 1680 bytes. There is no workaround.
