Caveats
Resolved Caveats—Cisco IOS Release 12.0(32)S
• CSCej00776
Symptoms: When you reload a line card or router and then remove a policy, the output of the show
policy-map interface command shows that no policy is applied but the output of the show
controller frf queue command does show that the queues are not fully released. This situation
prevents traffic from flowing correctly.
Conditions: This symptom is observed on a Cisco 12000 series that is configured with a Gigabit
Ethernet Engine 5 SPA that has an “L3/1C/nD” policy map attached to an interface.
Workaround: After you have removed the policy, reload microcode onto the SPA.
• CSCej01615
Symptoms: On a router that is configured for Multiprotocol Label Switching (MPLS) Label
Distribution Protocol (LDP), the CPU usage may increase considerably for an extended period of
time when a large number of label bindings are withdrawn or released at the same time.
Conditions: This symptom is observed on a Cisco router only when LDP (as opposed to TDP) is
used and when a large number (more than 250) of LDP neighbors and a large number of IP prefixes
become unreachable at the same time.
Workaround: There is no workaround.
• CSCej01743
Symptoms: Traffic drops may occur when traffic is sent over MFR or Frame Relay links.
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(28)S1 or a later release and that is configured for software forwarding.
Workaround: There is no workaround.
• CSCej04699
Symptoms: The output of the show ip hardware-cef tofab prefix command may display incorrect
information for Engine 5 line cards.
Conditions: This symptom is observed on a Cisco 12000 series that functions in a scaled routing
environment with more than 100,000 routes.
Workaround: There is no workaround.
• CSCej07539
Symptoms: Multicast traffic does not resume fully after you have removed the active PRP from the
router.
Conditions: This symptom is observed on a Cisco 12000 series that runs the c12kprp-p-mz image of
Cisco IOS Release 12.0(28)S4 and that is configured with redundant PRPs that function in RPR+
mode. The router has two channelized OC-12 line cards that are configured with mVPNs.
Workaround: There is no workaround.
• CSCej09234
Symptoms: The standby RP on a Cisco 12000 series may fail to come up and crash during
initialization. The primary RP may generate the following error message:
%MBUS-6-DEADSCDY: Standby RP in slot <x> timed out.
Conditions: This symptom is observed only when there is a large number of files for the standby RP
on the flash disk (for example, when a 1 GB flash disk is about half full) and when the average file
size is also large.
Workaround: Delete files on the flash disk.
