Caveats for Cisco IOS Release 12.0

Resolved Caveats—Cisco IOS Release 12.0(6)
• CSCdm36128
A Cisco 3600 series router with 4T dial out might go down when you issue the
dialer dtr command. There is no workaround.
• CSCdm37466
Spurious accesses, router hangs, or router reloads can occur if you use fair queuing. There is no
workaround.
• CSCdm38433
A VIP configured for Distributed Cisco Express Forwarding (CEF) and Cisco Encryption
Technology chassis (CET) might reload after you remove and reapply the crypto maps.
Workaround: Apply the crypto maps one at the time and to go back to privilege mode between
issuing the commands.
• CSCdm43653
The process switching of Multiprotocol Label Switching (MPLS) packets received on an
AAL5SNAP PVC subinterface fails. There is no workaround.
• CSCdm44057
When running virtual profile, a Cisco 7500 series router continually resets the CBus. The following
message is displayed:
%RSP-3-RESTART: interface Serial4/0:1, output stuck
Some time later, a reset occurs on the CBus. When you debug the CBus, you see the bus resetting
which causes all attached controllers to loose connectivity. The only way to access the router is
through the console port. There is no workaround.
• CSCdm44726
Cisco IOS Release 11.3AA images do not support online insertion and removal (OIR) for ATM port
adapters. If you OIR an ATM port adapter more than once, the router will hang. There is no
workaround.
• CSCdm48870
IPSec reports an incorrect MTU size. Crypto does not recognize an initial ip mtu command on an
interface to which a crypto map has been applied. There is no workaround.
• CSCdm54169
You cannot change the MTU size of a tunnel interface using software after Cisco IOS
Release 11.3(9.2).
Workarounds:
–
Use images between Release 11.3(5.1)T and Release 11.3(9.3) or Release 12.0(0.16) and
Release 12.0(4.2).
–
Configure ip mtu on the tunnel interface before you configure tunnel destination. If
tunnel destination is already configured, then unconfigure the destination, configure ip mtu,
and then reconfigure the destination. You need to wait five seconds after removing the tunnel
destination before issuing the ip mtu command. Once the workaround is issued, there should
be no problems in the event of a router reboot as the ip mtu command is parsed before the
tunnel destination.
• CSCdm55084
When an SDR session is defined with a PA-A3 port adapter, a Cisco router might reload. There is
no workaround.
