Hello Dragoljub,

Qos on vlan interfaces is not supported for FP140/FP40 LCs.

“MQC-based QoS configuration will be accepted only on the port level but not on the VLAN subinterface level.”

Actualy it is possible to match VLAN on physical interface and make something like this.

interface TenGigE0/0/0/0

service-policy input customers-qos

service-policy output customers-qos

interface TenGigE0/0/0/0.100

desc customerA

interface TenGigE0/0/0/0.101

desc customerB

class-map match-any vlan100

match vlan 100

end-class-map

!

class-map match-any vlan101

match vlan 101

end-class-map

policy-map customers-qos

class vlan100

  police rate XXX mbps

   conform-action transmit

   exceed-action drop

  !

!

class vlan101

  police rate XXX mbps

   conform-action transmit

   exceed-action drop

  !

!

This works perfect.

Hello, 

I am trying to configure QoS in CRS with FP140. We have the release 4.2.1.

This link has an example but we are receiving the same error.

Do you know if this support is hardware based?

Thank you
