Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(27)S
• CSCeb48648
Symptoms: A Cisco 7500 series Frame Relay VC may not come up when configured as a
cross-connect over an MPLS core.
Conditions: This symptom is observed on a Cisco 7500 series that functions as a provider edge (PE)
router and that provides a Frame Relay connection via an Any Transport over Multiprotocol Label
Switching (AToM) tunnel over a core interface that is configured to use RSP-based Weighted Fair
Queueing (WFQ).
Workaround: Configure VIP-based queueing on the core-facing interface.
• CSCeb51428
Symptoms: A Cisco router may reload unexpectedly after you have modified an access control list
(ACL) and have entered the clear pxf interface privileged EXEC command.
Conditions: This symptom is observed on a Cisco 10000 series.
Workaround: Do not enter the clear pxf interface privileged EXEC command.
• CSCeb52270
Symptoms: An interface of a Cisco router may not be able to receive traffic that is destined for an
address that is configured on the router.
Conditions: This symptom is platform independent and occurs only when there is a route in a
different VPN routing and forwarding instance (VRF) that is attached or connected to the interface.
This may occur when the route has been exported from one VRF to another or when a static route
in a VRF points to the interface.
Workaround: Enter the shutdown interface configuration command followed by the no shutdown
interface configuration command on the affected interface.
• CSCeb52414
Symptoms: When a Multiprotocol Label Switching (MPLS) traffic engineering (TE) headend
receives a Resource Reservation Protocol (RSVP) path error message (with error code 25, “Notify”),
the headend may tear down the label switched path (LSP) for the tunnel on which the path error
message arrived, causing loss of packets on the affected tunnel.
Conditions: This symptom is observed when the headend is a Cisco router that runs Cisco IOS
Release 12.0(26)S or an earlier release and when some midpoint router generates a path error
message (with error code 25, “Notify”) by using an error value other than 3. (An error value of 3
indicates that the tunnel is locally repaired.)
Workaround: There is no workaround.
• CSCeb53323
Symptoms: Packets may be forwarded to and switched on the Route Switch Processor (RSP) rather
than on a Versatile Interface Processor (VIP).
Conditions: This symptom is observed on a Cisco 7500 series that runs Cisco IOS Release 12.0 S
when the Ethernet port on a VIP is configured for the Any Transport over MPLS (AToM): Ethernet
over MPLS: Port Mode feature.
Workaround: There is no workaround. The symptom occurs intermittently and normally can correct
itself.
