• CSCsa56415
Symptoms: A router may pause indefinitely or reload unexpectedly.
Conditions: This symptom is observed while deleting or recreating policing access control lists
(ACLs) or shaping ACLs via a script.
Workaround: Update the access control list (ACL) rather than delete it.
• 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
