IOS XR - Hierarchical Modular QoS - conform-action set dscp

[ashilabdulla]

Hi group,

Trying to configure Hierarchical Modular QoS on Cisco N540 series (N540-24Z8Q2C-M). IOS XR version 7.5.2

The following command gets rejected during commit. Has anyone encountered the same?

"conform-action set dscp ef" under QoS policing configuration (see output of 'show config failed' below)

-----------------------------------------------

policy-map PM-CHD-PLR
class realtime
police rate 38000000 bps burst 80000 bytes peak-rate 38000000 bps peak-burst 80000 bytes
conform-action set dscp ef
!
!
class class-default
!
end-policy-map
!
!!% Qos verification failed for policy-map.: Policy-map PM-CHD-PLR class realtime failed: Number of actions for 'police conform' exceeds limit 0
end

--------------------------------------------------------

Thanks in advance.

Cheers
