Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(27)S
• CSCec26773
Symptoms: A router may reload when there is an active intercept and a Performance Routing Engine
(PRE) cutover occurs.
Conditions: This symptom is observed on a Cisco 10000 series that is running the c10k-u2p10-mz
image of Cisco IOS Release 12.0(25)S1.
Workaround: There is no workaround.
• CSCec27278
Symptoms: On a Cisco router that is configured with a Multilink PPP (MLP) interface, the available
processor memory may decrease rapidly because of a memory leak.
Conditions: This symptom is observed when the MLP interface flaps repeatedly.
Workaround: There is no workaround. You must resolve the cause of the flapping MPL interface.
• CSCec28540
Symptoms: A Cisco 7200VXR router generates a traceback that points to memory depletion after
the Cisco IOS software loads on the router.
Conditions: This symptom is observed on a Cisco 7200VXR that is configured with Multiprotocol
internal Border Gateway Protocol (MP-iBGP) to create Multiprotocol Label Switching (MPLS)
Virtual Private Network (VPN) sessions. After a few minutes, tracebacks are generated and I/O
memory is depleted.
Workaround: There is no workaround.
• CSCec30795
Symptoms: If traffic passes on multiple ports of an 8-port Fast Ethernet (FE) card and the shutdown
interface configuration command is entered on one of the traffic-flowing ports, all the other ports
stop passing traffic.
Conditions: This symptom is observed on a Cisco 10000 series with an 8-port Fast Ethernet (FE)
card that is running a Performance Routing Engine 1 (PRE1) image of Cisco IOS
Release 12.0(23)S4. There is no special configuration required to experience this symptom. Ports
that pass traffic with a basic default configuration will experience the symptom.
Workaround: Enter the no shutdown interface configuration command to free the other ports. Do
not shut down any port on an 8-port Half Height (HH) FE line card until a fix is available.
• CSCec30960
Symptoms: A Cisco router may reload when deconfiguration and configuration files are copied to
the router for a 1-port OC12 ATM line card.
Conditions: This symptom is observed on a Cisco 10000 series router when Automatic Protection
Switching (APS) is configured for the 1-port OC12 ATM line card.
Workaround: There is no workaround.
• CSCec31110
Symptoms: The output from the show interfaces gige stats EXEC command may incorrectly
display a large value.
Conditions: This symptom is observed on a Gigabit Ethernet (GE) interface in a PPP over Ethernet
(PPPoE) environment.
Workaround: There is no workaround.
