Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Caveats
Resolved Caveats—Cisco IOS Release 12.0(32)S
interface ATM1/0.100 point-to-point
ip unnumbered Loopback10
atm route-bridged ip
range pvc 6/100 6/599
There are four workarounds:
Enter the shutdown interface configuration command followed by the no shutdown interface
configuration command on the physical interface.
Enter the no pvc-in-range command followed by the pvc-in-range command on a wedged VC.
Enter the shutdown interface configuration command followed by the no shutdown interface
configuration command on an uplink interface.
Tear down and rebuild a PVC.

Symptoms: Multicast traffic may be incorrectly dropped if it is filtered by an IPv6 ACL that matches
on source and destination address.
Conditions: This symptom is observed when a Cisco 12000 series that runs Cisco IOS
Release 12.0(31)S and that performs IPv6 ACL filtering.
Workaround: Ensure that the any keyword is configured for the ACE instead of a source address,
that is, enter the permit protocol any multicast-ipv6-prefix/prefix-length sequence value command.
CSCsb02964
Symptoms: When a class map that contains an access control list (ACL) that is too large and
complex to fit in memory is applied to an MQC policy map on a Cisco 10720, the router pauses
indefinitely while compiling the ACL and generates a MALLOCFAIL error. The router should
report an out-of-memory situation.
Conditions: This symptom is observed when the ACL contains 2000 lines and is complex.
Workaround: There is no workaround.
CSCsb04721
Symptoms: When the Any Transport over MPLS (AToM) feature is enabled on a router, AToM
virtual circuits to a peer may not be re-established after an interface flap or after being reconfigured,
because the required targeted Label Distribution Protocol (LDP) session is not re-established.
Conditions: This symptom is observed when LDP is not configured on any interfaces via the mpls
ip interface configuration command, which is typically the case when MPLS Traffic Engineering
(TE) tunnels are used to transport AToM traffic between endpoints and when the mpls ip interface
configuration command is not enabled on any TE tunnels.
The symptom occurs in Cisco IOS software releases that include the fix for caveat CSCec69982
when any form of one of the following commands is configured on the router and appears in the
running configuration:
mpls ldp explicit-null
mpls ldp advertise-labels
mpls ldp session protection
mpls ldp password fallback
mpls ldp password option
mpls ldp password required
