Resolved Caveats—Cisco IOS Release 12.0(27)S
• CSCea29102
This caveat consists of two symptoms, two conditions, and two workarounds:
1.
Symptoms: A Route Processor (RP) may reload when you enter the clear ip bgp * privileged EXEC
command while interfaces flap continuously.
Conditions: This symptom is observed when Virtual Private Network (VPN) routing/forwarding
(VRF) forwarding is configured on the interfaces that flap.
Workaround: There is no workaround.
2.
Symptoms: An RP may reload when you simultaneously enter the clear ip bgp * privileged EXEC
command and perform an online insertion and removal (OIR) by entering the hw-reload reset
EXEC command.
Conditions: This symptom is observed when you perform an OIR of an interface that has a VRF
configuration in which the connected route is learned via a network statement. The connected route
is removed when you perform the OIR.
Workaround: Do not simultaneously enter the clear ip bgp * privileged EXEC command and
perform an OIR.
• CSCea53696
Symptoms: A FlexWAN module that is configured with a 1-port multichannel STM-1 port adapter
(PA-MC-STM-1) may reload unexpectedly.
Conditions: This symptom is observed on a Cisco 7600 series when you apply Class-Based
Weighted Fair Queueing (CBWFQ) on the PA-MC-STM-1 to a Multilink PPP (MLP) bundle that
has E1 channels.
Workaround: There is no workaround.
• CSCea62519
Symptoms: Although traffic passes correctly when Frame Relay data-link connection identifier
(DLCI) is configured, the output of the show frame-relay pvc privileged EXEC command does not
display the input and output packets correctly.
Conditions: This symptom is observed on a 1-port OC-12 Packet-over-SONET (POS) line card and
a 6-port OC-3 POS line card that are installed in a Cisco 10000 series that is running Cisco IOS
Release 12.0(24)S when Frame Relay DLCI is configured on the line cards.
Workaround: There is no workaround. Note that the symptom does not occur in Release 12.0(23)S.
• CSCea66218
Symptoms: When a Tributary Unit Alarm Indication Signal (TU-AIS) is inserted for an E1 tributary
on a 1-port multichannel STM-1 port adapter (PA-MC-STM-1) in an Synchronous Payload Envelope
(SPE), packet corruption may occur on the adjacent E1.
Conditions: This symptom is observed on a Cisco 7200 series and a Cisco 7500 series.
Workaround: There is no workaround.
• CSCea69601
Symptoms: A flash Advanced Technology Attachment (ATA) disk card may become corrupted
because of simultaneous accesses to the card. The corruption may not be immediately obvious.
Signs of corruption are as follows:
– You cannot use an image from the ATA disk card to boot up the router.
