Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Caveats
Resolved Caveats—Cisco IOS Release 12.0(31)S1
Conditions: This symptom is observed on a Cisco router that is configured for Multilink Frame
Relay (MFR) over L2TPv3/AToM when there are services with incomplete MFR over
L2TPv3/AToM configurations and when the router has run for a long period of time.
Workaround: There is no workaround.
CSCsb00493
Symptoms: Packets do not switch through a core interface of a line card that has hardware
acceleration enabled.
Conditions: This symptom is observed on a Cisco 12000 series when the line card that contains the
core interface has also a VRF interface that is shut down.
Workaround: Disable hardware acceleration on the line card.
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
A list of the affected releases can be found at
http://www.cisco.com/cgi-bin/Support/Bugtool/onebug.pl?bugid=CSCec69982.
Workaround: Enter the mpls ip command on a TE tunnel interface or temporarily on a physical
interface to force LDP to be re-established.
CSCsb05218
Symptoms: An IPv6 ACL configuration may be lost or incorrect after an SSO switchover.
Conditions: This symptom is observed when a Cisco 12000 series performs IPv6 ACL filtering and
when the ACL is modified.
Workaround: There is no workaround.
