Caveats
Resolved Caveats—Cisco IOS Release 12.0(32)S
Conditions: This symptom is observed when any of the following conditions occur:
–
A link-bundle member that contains subinterfaces is re-added to a port channel.
–
A link-bundle member that contains subinterfaces is moved from one port channel to another.
–
A normal Gigabit Ethernet interface that contains subinterfaces becomes a link-bundle member.
Workaround: There is no workaround.
Further Problem Description: The root cause of the symptom is any operation that involves the
recreation of a subinterface re-creation with a link bundle.
• CSCsc14522
Symptoms: In a VPN topology, when you enter the hw-module slot x qos interface queues 8
command on a 1-port channelized OC-12 (DS3) ISE line card, traffic does not go through MLP
links.
Conditions: This symptom is observed on a Cisco 12000 series that runs an interim release for
Cisco IOS Release 12.0(32)S.
Workaround: There is no workaround.
• CSCsc15449
Symptoms: An Engine 5 SPA continuously crashes when 2000 unique egress policies are applied to
VLAN subinterfaces.
Conditions: This symptom is observed on a Cisco 12000 series and is related to a timing issue.
Workaround: There is no workaround.
• CSCsc16910
Symptoms: In an MVPN topology, an Engine 4+ POS line card that is located in the network core
may punt packets with a size of 1477 bytes or more to its CPU.
Conditions: This symptom is observed on a Cisco 12000 series that runs an interim release for
Cisco IOS Release 12.0(32)S.
Workaround: There is no workaround.
• CSCsc18661
Symptoms: When you send multicast traffic at or above 32 Kpps, the PXF buffers may deplete until
they are exhausted.
Conditions: This symptom is observed on a Cisco 10720 when ACL logging is configured to deny
multicast traffic at a rate of 32 Kpps and above.
Workaround: Do not use ACL logging for high-rate multicast streams.
• CSCsc20453
Symptoms: After an SSO switchover, interfaces of a channelized T1/E1 SPA go down and do not
recover.
Conditions: This symptom is observed on a Cisco 12000 series that is configured with two PRP2
processors that function in SSO mode when you enter the redundancy force-switchover command.
Workaround: Enter the shutdown command followed by the no shutdown command on the
controller of the SPA to bring up the interfaces.
• CSCsc22726
Symptoms: A SIP-600 in which a 10-port Gigabit Ethernet SPA is installed resets because of an IPC
timeout.
