OL-1617-14 Rev. Q0
Caveats
Resolved Caveats—Cisco IOS Release 12.0(33)S6
CSCsz72591
Symptoms: A router crashes with an Address Error (load or instruction fetch) exception.
Conditions: The router must be configured to act as a DHCP client.
Workaround: There is no workaround.
CSCsz78479
Symptoms: When the PE routes traffic with a default network, it suddenly stops forwarding the
packets from the CE. The PE is still able to reach the Internet.
Conditions: The PE is configured with the ip default network command and has an Engine 5.
Workaround: Remove and re-add the ip default network command.
Further Problem Description: The issue was already reproduced on the CALO case.
CSCsz81356
Symptoms: E6 linecards crash immediately after a CSC switchover.
Conditions: The CSC switchover is caused by a CSC card failure or by the CLI shutting down the
primary CSC.
Workaround: There is no workaround.
CSCsz84906
Symptoms: The ISIS redistribution RIB has a stale route that is not removed after the original ISIS
route is deleted when an interface is shut down. This can cause wrong ISIS database information and
wrong routing information in the routing table.
Conditions: This symptom is observed when the router is an L1L2 router and the old ISIS route to
be deleted after interface shutdown has a backup route from other routing protocols. If the ip
routing protocol purge interface command is configured, the issue will not happen.
Workaround: Either configure the ip routing protocol purge interface command or enter the clear
isis * command, which may resolve the problem temporarily.
CSCsz89090
Symptoms: When the delay triggers line command is executed under a controller, the configured
values are not reflected in the running configuration.
Conditions: This symptom is observed in Cisco IOS Release 12.0(33)S and 12.0 (32)SY9 images.
Workaround: There is no workaround.
CSCsz89107
Symptoms: CPU utilization is high when there is a scaled configuration of more than 1000 interfaces
and 100-pps traffic is being sent on UUT along with BGP and multicast traffic.
Conditions: This symptom is observed when several sessions are active and generating traffic.
Workaround: There is no workaround.
CSCta08632
Symptoms: After supervisor forces switchover several times, a router two hops away has wrong ISIS
topology and ISIS routing table.
Conditions:
1. Incremental shortest path first (ISPF) enabled in ISIS.
2. set-overload-bit on-startup in ISIS.
