Cross-Platform Release Notes for Cisco IOS Release 12.0S

OL-1617-14 Rev. Q0

Caveats

Resolved Caveats—Cisco IOS Release 12.0(30)S

%LCINFO-3-CRASH: Line card in slot 4 crashed

Conditions: The symptom is seen when the ciscoOpticalMonitoringMIB is polled on a router

running Cisco IOS Release 12.0(27)S1. The card that crashes does not have to be the card that is

being polled. For example, an OC192E/POS-VSR in slot 0 may be polled with

1.3.6.1.4.1.9.10.83.1.1.1.1.8.2 and the OC192E/POS-IR-SC in slot 4 may crash.

Workaround: Stop the crashes by configuring an SNMP view that prevents the

ciscoOpticalMonitoringMIB from being polled.

• CSCef25953

Symptoms: DSCP-based DWRED statistics are not updated in output of the show policy-map

interface command: random drop and tail drop statistics are always shown as zero.

Conditions: This symptom is observed on a Cisco 7500 that is configured with an RSP4. However,

this caveat may be platform-independent.

Workaround: There is no workaround.

• CSCef26053

Symptoms: Load-balancing does not work over a BGP multipath. Some of the traffic may be

forwarded correctly while other traffic may be forwarded unlabeled into the MPLS core.

Conditions: This symptom is observed on a Cisco router that functions as a PE router when the

following conditions are present:

–

The affected route is in a VRF.

–

One of the paths is learned from a CE router via an eBGP multihop session.

–

The eBGP multihop peer (that is, the CE router) is reachable through the MPLS core and the

BGP session does not involve a label exchange.

Workaround: Avoid a multihop eBGP session in which the CE router is reachable through the MPLS

core. For example, instead of a configuration in which the CE router connects to the PE router across

the MPLS core, configure the CE peer to connect to a local PE router that redistributes the routes it

has learned from the CE peer to other PE routers. (The local PE router may need to be configured

for eiBGP multipath.)

• CSCef26077

Symptoms: Unconfiguring link bundling on a GE interface causes a bus error on the RP.

Conditions: This symptom is observed on a Cisco 12000 series that runs a Cisco IOS interim release

of Release 12.0(30)S. However, this caveats is resolved in Release 12.0(30)S.

Workaround: There is no workaround.

• CSCef26186

Symptoms: After a router reloads, Engine 0 POS and Engine 4+ POS line cards may reset because

of an “%MDS-2-LC_FAILED_IPC_ACK” error.

Conditions: This symptom is observed on a Cisco 12000 series that runs the gsr-p-mz image of an

interim release for Cisco IOS Release 12.0(30)S and that has multicast enabled in global

configuration mode. Note, however, that this caveat is resolved in Release 12.0(30)S.

Workaround: There is no workaround.

• CSCef26370

Symptoms: When you copy a Cisco IOS image or any other file to a PC flash card via TFTP, a very

high rate of out-of-sequence packets occurs, which can be seen in the “!0!00!0!00!0!0...” output of

the copy tftp slot-number command.
