I have this ACL written: 

entry surfacehub {
if match all { source-address 172.16.12.120/32; } then { Qosprofile qp5; replace-dscp; } }
 
QP5 has had it's diffserve value changed to 34 (which is AF41)
Slot-1 IDF02.38 # sh diffserv replacement
QOSProfile->CodePoint mapping:
        QP1 -> 00
        QP5 *> 34
        QP6 *> 46
        QP8 -> 56

What direction do I apply the ACL to the port?  Ingress or Egress?

Slot-1 IDF02.42 # configure access-list surfacehub ports 1:21 ingress
 
I'm assuming ingress, but I'm not seeing anything on qosmonitor:

Slot-1 IDF02.43 # sh port 1:21 qosmonitor

The IP address and port is definitely correct:

IDF02.44 # sh iparp | i 172.16.12.120
VR-Default    172.16.12.120    90:fb:a6:e5:e3:fb    0      NO  OFFICE        22    1:21

Is the direction correct?
Why am I not seeing traffic from 172.16.12.120 being put into QP5 on qosmonitor?

Welp, looks like I forgot to refresh the policy.

After a test call all is looking like it should.  The Hub already tags voice as DSCP 46 and now the video traffic is being tagged as AF41
