Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Caveats
Resolved Caveats—Cisco IOS Release 12.0(32)S
CSCsc58973
Symptoms: When the mpls ping and traceroute commands are configured, the specified destination
address does not take effect, nor is the 127.0.0.1 default address used when the destination address
is not specified. Instead, the target FEC is used as the destination IP address in IP header of the
outgoing packet.
When you specify a range of destinations for troubleshooting, the target IP address is always used.
This situation prevents you from using the mpls ping and traceroute commands to troubleshoot an
equal-cost multipath (ECMP) configuration.
Conditions: This symptom is observed on a Cisco router that runs Cisco IOS Release 12.0S.
Workaround: There is no workaround.
CSCsc61616
Symptoms: A 1-port channelized OC-3/STM-1 Engine 5 SPA may crash when you delete an MLP
bundle that has 12 links and that is configured on the SPA.
Conditions: This symptom is observed on a Cisco 12000 series when you perform an OIR of the
SPA, enter the hw-module reload for the SPA, and then delete the MLP bundle from the SPA.
Workaround: There is no workaround.
CSCsc63558
Symptoms: A 2-port OC-192 POS Engine 6 line card (the 2OC192/POS-SR-SC and the
2OC192/POS-IR-SC) may stop forwarding traffic after running properly for a while. When this
situation occurs, the POS interface is in the UP/UP state, but a ping to the directly connected POS
interfaces fails. No error messages are generated for the affected line card.
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(28)S2 or Release 12.0(28)S5, irrespective of whether or not an ACL is configured on
the line card.
Workaround: There is no workaround. You must reset the line card to recover from the symptoms.
CSCsc64384
Symptoms: Traffic does not flow on some ports (ports 6 through 9) of a 10-port Gigabit Ethernet
Engine 5 SPA.
Conditions: This symptom is observed on a Cisco 12000 series that is configured with a SIP-601
that has 10-port Gigabit Ethernet Engine 5 SPAs in Bay 0 and Bay 1.
Workaround: There is no workaround.
CSCsc64723
Symptoms: After an SSO switchover, traffic does not fully recover on a 3-port GE Engine 2 line card
that is configured for EoMPLS.
Conditions: This symptom is observed on a Cisco 12000 series that runs the c12kprp-p-mz image of
Cisco IOS Release 12.0(28)S5.
Workaround: Enter the clear cef linecard slot-number command to recover from the symptom and
enable traffic to pass properly.
CSCsc66887
Symptoms: All line cards on a Cisco 12000 series may reload when you configure a named ACL.
Conditions: This symptom is observed with the following configuration sequence:
1. You configure an IPv4 numbered (1-99) standard ACL.
2. You remove the IPv4 numbered standard ACL.
