Cross-Platform Release Notes for Cisco IOS Release 12.0S

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.
