Cisco Cisco IOS Software Release 12.2

CSCeb73681

Symptoms: The main High-Speed Serial Interface (HSSI) interface flaps when you enter the 
map-class frame-relay global configuration command on a subinterface.

Conditions: This symptom is observed only when map class contains both traffic shaping and 
Random Early Detection (RED).

Workaround: Use only traffic shaping under the map-class. 

CSCec32135

Symptoms: “Set” based service-policy can cause the router to reload in some circumstances. The set 
cos command can cause reloads in addition to other set commands. 

Conditions: This problem may be seen with configurations that have a service-policy with the set 
command on the interface in combination with one or all of the below three configurations:

access-list filtering 

unicast rpf 

multicast routing 

Under such circumstances, configuration changes of the “set” based policy-map can cause the router 
to reload.

Workaround: There is no workaround.

CSCin41510

Symptoms: An output service policy with a police feature may be rejected, and the following error 
message may be generated:

Cannot attach flat policy to pvc/sub-interface. Hierarchical policy with shape in 

class-default is recommended

Conditions: This symptom is observed when the output service policy is attached to multiple 
subinterfaces.

Workaround: There is no workaround.
