OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(27)S2
Conditions: This symptom is only observed on an MPLS-capable Cisco platform and only when the
label space has been exhausted to the maximum level supported by the platform or is about to be
exhausted (only a few hundred labels are available) and when the TFIB table is expanded further.
Workaround: Enter the mpls label range 16 101900 command at the conf-t level to avoid the error
messages.
CSCec46191
Symptoms: When you securely copy a Cisco IOS image to a flash disk by entering the copy scp
slot0: or copy scp slot1: EXEC command, the copy process may stop after about 60 to 70 percent
has been transferred.
Conditions: This symptom is observed on a Cisco router that runs Cisco IOS Release 12.0(25)S1 or
Release 12.3.
Workaround: Copy the Cisco IOS image via another transport protocols such as TFTP.
CSCec77049

Switchover (SSO).
CSCec78545
Symptoms: A Versatile Interface Processor (VIP) may reload when the clear cef line command is
entered or when a new VRF is provisioned on an interface via the CLI.
Conditions: This symptom is observed on a VIP when Multiprotocol Label Switching (MPLS),
Egress NetFlow, and distributed Cisco Express Forwarding (dCEF) are configured.
Workaround: Disable dCEF or Egress NetFlow before making configuration changes or before
entering the clear cef line command.
CSCec80283
Symptoms: An IP Services Engine (ISE) line card may display high CPU utilization.
Conditions: This symptom is observed on an ISE line card in a Cisco 12000 series when
Multiprotocol Label Switching (MPLS) packets are sent to the nonlabel-switched interface of the
ISE line card.
Workaround: There is no workaround.
CSCed08168
Symptoms: No SNMP linkup or linkdown trap is generated for a 1CHOC12/4CHSTM1 SONET
layer when a controller goes up and down.
Conditions: This symptom is observed when monitoring a SNMP linkup or linkdown trap for a
1CHOC12/4CHSTM1 SONET layer.
Workaround: Monitor the controller status using the show controller sonet command.
CSCed10965
Symptoms: All line cards may crash due to an IPC timeout or fabric ping timeout.

conditions. The output of the show controllers psar command shows excessive error events (e.g.
free queue empty events).
