OL-1617-14 Rev. Q0
Caveats
Resolved Caveats—Cisco IOS Release 12.0(32)S9
CSCsj52296
Symptoms: After changing redundancy mode via SNMP on GSR redundancy mode description is
missing on SNMP O/P.
Conditions: Only on changing redundancy mode, this does not affect the functionality
Workaround: There is no workaround.
CSCsj58716
Symptoms: Traffic drops occur on egress SIP-X01 interface during congestion.
Conditions: The problem occurs when egress is any SIP-X01 card and there is congestion on the
outgoing interface and no default queue-limit is configured explicitly for the traffic class.
Workaround: The problem does not occur when a low limit is configured on the class and WRED is
also configured.
CSCsj62100
Symptoms: The show controller psar frfab packet_dump command has no effect.
Conditions: This command is used to capture corrupt packet data when assembler RP detects it.
Workaround: There is no workaround.
CSCsj62309
Symptoms: Unexpected flows are seen on a GSR configured with aggregate netflow and acting as a
provider edge router (PE). The unexpected flows is seen in the output direction of the CE-facing
interface (vrf interface).
Conditions: When traffic is generated (FTP, UDP, ICMP), we can observe strange flows of IP
precedence 5 (TOS A0). If there is no traffic flowing through, then the flows are not seen. The router
runs Cisco IOS Software 12.0(32)S6. Both ingress and egress linecards are ISE Engine 3 linecards.
The P-facing interfaces are bundled in a port-channel.
Workaround: There is no known workaround and this impacts customer billing.
Further Problem Description: The flows can be seen through the following command:
clk15ra#execute-on slot 3 sh ip cac ver flow agg as-tos | i Gi3/1.999 ========= Line
Card (Slot 3) ========= Gi3/1.999 0 PortCh1 0 00 64 121K 46 147.2 Gi2/0 0 Gi3/1.999* 0

CSCsj65683
Symptoms: Wrong channel group obtained from the CLI.
Conditions: Occurs when BERT is run on a channel group.
Workaround: There is no workaround.
CSCsj65713
Symptoms: Following unknown trigger events, a GSR running Cisco IOS version 120(32)S6 may
not properly classify PIM MDT-encapsulated multicast traffic via an MQC queueing policy attached
to a POS interface on an E3 POS linecard [4OC3X/POS-IR-LC-B=]. This symptom can be observed
via executing the show policy-map interface POS X/Y command while multicast traffic with
non-zero IP Precedence or DSCP Value is exiting the interface.
Conditions: The issue is observed on MDT encapsulated GRE multicast tunnel packets on a P router
in an MPLS core. The P router’s failing Line-Card is 4OC3X/POS-IR-LC-B= and the P router is
running Cisco IOS version c12kprp-p-mz.120-32.S3.
Workaround: There is no workaround.
