Resolved Caveats—Cisco IOS Release 12.0(27)S5
Workaround: Manually remove the export map from the new active RP.
• CSCsa58340
Symptoms: Upon entering the police command, the router reloads unexpectedly.
Conditions: The reload occurs if the policy map being edited already contains the maximum number
of classes that the Cisco 10000 supports and the user attempts to add one more class with police.
Workaround: Avoid using policy maps that contain more classes than what the Cisco 10000
supports.
• CSCsa59002
Symptoms: IP fragments with a User Datagram Protocol (UDP) protocol identifier may be
improperly denied on an Engine 3 line card that has an outbound access control list (ACL) that
denies specific UDP ports.
Conditions: This symptom is observed only for outbound ACLs on an Engine 3 line card on a Cisco
12000 series. The following is an example of an ACL statement for which the symptom may occur:
access-list 100 deny udp any any eq 0 <<< this line may accidently deny IP
fragments for UDP access-list 100 permit ip any any
Workaround: Use the following ACL instead of the above-mentioned example:
access-list 101 permit udp any any fragments
access-list 101 deny udp any any eq 0
access-list 101 permit ip any any
• CSCsa59109
Symptoms: At random, subinterfaces loose the ability to ping a directly-connected peer.
Conditions: This symptom is observed on a Cisco 12000 series that is configured with two 3-port
Gigabit Ethernet line cards.
Note that although regular and extended pings do not work, pings that use the record option do work.
Workaround: Reload microcode onto the affected line cards.
• CSCsa59829
Symptoms: With traffic passing over a network only occasionally, a 4-port OC12 ATM ISE line card
generates a “%PM622-3-CPK24_INTR: Egr SAR timeout” error message and resets.
Conditions: This symptom is observed on a Cisco 12000 series.
Workaround: Reload the line card.
Further Problem Description: The symptom occurs when the “CPK24 FPGA” detects that the SAR
does not respond in the “Utopia interface.” The SAR then crashes because of a bad canonical header
in the egress direction.
• CSCsa64782
Symptoms: When an ingress ISE line card is used with a default route that iBGP learns over a MPLS
core, the following two symptoms may occur:
- The output of the show controllers tofab alpha mip stat | i MTU command may show traffic
drops.
- Traffic is incorrectly sent as "unlabeled" over the MPLS core.
Conditions: These symptoms are observed on a Cisco 12000 series when the traffic path follows a
recursive default route and when recursive load sharing occurs.
Workaround: Prevent outbound load sharing to the default route by changing the IGP metrics.
