Hi,

Share the "'show configuration failed" output. 

I think the issue related to the Service-policy applied in input and output (both directions).

Hi,

Apply only to the input direction:

 

NCS540(config)#INTERFACE TENG 0/0/0/3
NCS540(config-if)# service-policy input 54STM

Hi,

I went through the documents and get some important details as

Usage Guidelines
Use the police command to mark a packet with different quality of service (QoS) values based on conformance to the service-level agreement.

Class-Based Policing will not be executed for traffic that passes through an interface.

Specifying Multiple Actions

The police command allows you to specify multiple policing actions. When specifying multiple policing actions when configuring the police command, note the following points:

•You can specify a maximum of four actions at one time.

•You cannot specify contradictory actions such as conform-action transmit and conform-action drop.

Hello,

 

according to the guide below, you can only do ingress traffic policing:

 

Restrictions


Traffic policing is supported only in ingress direction, and only color-blind mode is supported.
