OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(27)S
• CSCeb78610
Symptoms: The interface protocol may not come up for a 1-port OC-12 Packet-over-SONET (POS)
line card when the encapsulation frame-relay interface configuration command is configured.
Conditions: This symptom is observed on a Cisco 10000 series when the 1-port OC-12 POS line card
is connected back-to-back to another line card in another Cisco 10000 series.
Workaround: There is no workaround.
• CSCeb79576
Symptoms: An outgoing label may not be installed in the Label Forwarding Information Base
(LFIB) for an IP version 4 (IPv4) prefix.
Conditions: This symptom is observed when the prefix is learned via a Border Gateway Protocol
(BGP) session. This situation may occur when the prefix is deleted in the Label Information Base
(LIB) and not allocated to any local label binding.
Workaround: There is no workaround.
• CSCeb79911
Symptoms: Backward explicit congestion notification (BECN) packets may be dropped by an Any
Transport over Multiprotocol Label Switching (AToM) tunnel.
Conditions: This symptom is observed when you configure AToM in the network core, the network
core contains Frame Relay interfaces, and BECN is enabled.
Workaround: There is no workaround.
• CSCeb80481
Symptoms: A memory leak may occur in the “SNMP Engine” process, which can be verified in the
output of the show processes memory | SNMP ENGINE privileged EXEC command.
Conditions: This symptom is observed in Cisco IOS Release 12.0(26)S and Release 12.2(18)S when
you enter the snmpget command for the MPLS-LSR-MIB MIB.
Workaround: There is no workaround.
• CSCeb80992
Symptoms: A Catalyst 6000 series Supervisor 2 may reload unexpectedly because of a bus error.
Conditions: This symptom is observed when access control list (ACL) counters are sent from a line
card to the Route Processor (RP) and when the ACL number is in the expanded range (that is, from
1300 to 1999 or from 2000 to 2699).
Workaround: There is no workaround.
• CSCeb82737
Symptoms: When you shut down the last port of an 8-port Fast Ethernet half-height line card (port
7), all other ports on the line card may stop transmitting traffic.
Conditions: This symptom is observed on a Cisco 10000 series.
Workaround: Do not shut down port 7. If port 7 is shut down, enter the no shutdown interface
configuration command on the interface to enable traffic to resume on the other interfaces.
• CSCeb86270
Symptoms: In Cisco IOS software that is running Multiprotocol Label Switching (MPLS), the Label
Distribution Protocol (LDP) peer address table may become corrupted and cause the router to
reload.
