Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S1
• CSCef25872
Symptoms: An OC192E/POS-IR-SC line card in a Cisco 12000 series may crash with the following
messages:
%GRP-4-RSTSLOT: Resetting the card in the slot: 4,Event: linecard error report
%MDX-1-DAEMSGSNDFAILED: FAILED to send IPC message of TYPE MDX_DAE_PULL_REQ to
slot 4 on the DAE,
FAIL REASON = retry queue flush
%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.
• CSCef27191
Symptoms: It is not possible to change the duplex configuration to full duplex on a Fast Ethernet
(FE) interface of a Cisco 7200 series. When you enter the full-duplex interface configuration
command, the command is ignored. The parser accepts the command, but it is not shown in the
output of the show running-config command and the output of the show interface command shows
the FE interface as half-duplex.
Conditions: This symptom is observed when the FE interface belongs to a PA-2FEISL-FX or
PA-2FEISL-TX port adapter and when the Cisco 7200 series runs Cisco IOS Release 12.0(28)S or
a later release.
Workaround: There is no workaround.
• CSCef27580
Symptoms: Policy-based routing (PBR) loadsharing does not occur.
Conditions: This symptom is observed on a Cisco 12000 series when PBR loadsharing is enabled
via the set next-hop recursive command and when routes to the destination are available via
multiple interfaces. When you enter the shutdown interface configuration command followed by the
no shutdown interface configuration command on the interface that connects to the next-hop (or
when the interface goes down and comes back up), traffic does not resume on this interface.
Workaround: Enter the static arp command on the interface that connects to the next-hop.
• CSCef28848
Symptoms: The following error message is generated repetitively for an ATM OC-12 line card:
%FIA-3-REQUESTERR: Request error was detected. Type = 1
The output of the show controller fia command shows that the “Empty dst request” field continues
to increment for the line card, and the line card is unable to pass multicast traffic.
Conditions: This symptom is observed on a Cisco 12000 series when multicast packets do not have
their Cisco cell fields properly set.
Workaround: There is no workaround.
• CSCef31649
Symptoms: A VRF interface receives auto-RP discovery packets only once via the core link. After
that, no more RP discovery packets are received. After three minutes, the RP mapping table ages
out, preventing multicast traffic from being passed.
