Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S2
• CSCeg11421
Symptoms: A Cisco 10720 crashes when you delete an IPv6 ACL.
Conditions: This symptom is observed when you delete the IPv6 ACL during the TurboACL
compilation.
Workaround: Wait for the ACL to be fully compiled before you delete it.
• CSCeg13868
Symptoms: When the no tag-switching ip propagate-ttl command is configured on PE routers and
a traceroute is executed from one CE router to a remote CE router, an egress PE router replies to the
traceroute with the address of its ingress MPLS interface.
Conditions: This symptom is observed only when the traceroute is destined for a network between
an egress PE router and a remote CE router, when the ingress line card of the egress PE router is a
Cisco 12000 series Engine 0 or Engine 1 line card.
Workaround: There is no workaround.
• CSCeg15191
Symptoms: An OC192E/POS-IR-SC line card resets with the following error messages:
%MBUS_SYS-3-NOBUFFER: Message from slot 3 in stream 1 dropped
%MDS-2-LC_FAILED_IPC_ACK: RP failed in getting Ack for IPC message of size 232 to LC
in slot 3 with sequence 47350, error = timeout %FIB-3-FIBDISABLE: Fatal error, slot
3: IPC Failure: timeout
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(28)S1.
Workaround: There is no workaround.
• CSCeg16631
Symptoms: When you enter the distribute-list interface command in a global RIP routing context
and the interface that is specified in the command is a VRF interface, the command is rejected with
the following error message:
% The interface is not in the same VRF as the process
Because the distribute-list interface command is not implemented in the IPv4 VRF address-family,
there is no other way to filter networks received in updates via a VRF interface.
Conditions: This symptom is observed in all Cisco IOS releases that integrate the fix for
CSCee32557. A list of the affected releases can be found at
http://www.cisco.com/cgi-bin/Support/Bugtool/onebug.pl?bugid=CSCee32557. Cisco IOS
software releases that are not listed in the “First Fixed-in Version” field at this location are not
affected.
Workaround: In a configuration that is mentioned above, to filter networks received in updates, enter
the distribute-list extended-ACL-reference command in which the “source-part” of the extended
ACL specifies the prefixes and the “destination part” matches on the IP address of the RIP neighbor.
• CSCeg28402
Symptoms: Spurious memory accesses may occur on a Cisco 7500 series and may cause high CPU
usage on the RSP.
Conditions: This symptom is observed on a Cisco 7500 series that is configured for distributed
Multilink PPP (dMLP) and that functions in an MPLS network.
Note that packet switching for MPLS packets over MLP bundles is not supported at the RSP level
in Cisco IOS Release 12.0S.
