QoS config error - Cisco ME-3400EG

[GeorgeChondrogiannis67082]

Hello team,

I was hoping if anyone could assist me with the below issue I ran into this morning. 

On my Cisco 3440 switch, I am trying to configure a new policy-map, using the existing class-maps but when  I am adding a policer I am getting the error config below. 

(config-pmap-c)#police cir 400000000
Configuration failed. Police action cannot be configured along with the other configured action

(config-pmap-c)#

This policy-map has not been applied to any interface yet using a service policy, however for some reason the system will not accept it. The policy-map below, without a policer, is working just fine, but we need to add policing to enforce slower bitrates for a particular interface. 

policy-map OUT-1G-QOS-BASED
class qos-Real-Time
priority
class qos-Video
bandwidth remaining percent 20
class qos-Business
bandwidth remaining percent 60
class class-default
bandwidth remaining percent 20

Any ideas/suggestions of what am i doing wrong here?

Thanks in advance,

George

Hello,

looking at the guidelines in the QoS guide linked below:

--> To configure priority with unconditional policing, configure the priority queue by using the priority policy-map class configuration command and the police policy-map class configuration command to unconditionally rate-limit the priority queue. In this case, you can configure the other traffic classes with bandwidth or shape average, depending on requirements.

I think only the 'bandwidth percent' is allowed.

Try this:

policy-map OUT-1G-QOS-BASED
class qos-Real-Time
priority

--> police cir 400000000
class qos-Video
--> bandwidth percent 20
class qos-Business
--> bandwidth  percent 60
class class-default
--> bandwidth  percent 20

Better yet, use shaping instead of policing:

policy-map OUT-1G-QOS-BASED
class qos-Real-Time
priority

--> shape average 400000000
class qos-Video
--> bandwidth percent 20
class qos-Business
--> bandwidth  percent 60
class class-default
--> bandwidth  percent 20
