Inbound vs Outbound on policy map

[billmatthews]

I have Cisco 2900 routers running IOS 15.1.  I have a pair of routers with a serial interface into an MPLS network (T1)...

LAN1 - R1 - MPLSWAN - R2 - LAN2

Here is the existing QoS config:

interface Serial0/0/0

bandwidth 1536

max-reserved-bandwidth 100

service-policy input SERIAL-QOS-INBOUND

service-policy output SERIAL-QOS-OUTBOUND

!

policy-map SERIAL-QOS-OUTBOUND

class TAG-EF

  set dscp ef

  priority 480

class TAG-AF31

  set dscp af31

  bandwidth remaining percent 10

class TAG-AF21

  set dscp af21

  bandwidth remaining percent 35

class TAG-AF11

  set dscp af11

  bandwidth remaining percent 10

class class-default

  set dscp default

  bandwidth remaining percent 25

policy-map SERIAL-QOS-INBOUND

class TAG-EF

  set dscp ef

class TAG-AF31

  set dscp af31

class Video

  set dscp af21

  police cir 512000

   conform-action transmit

   exceed-action drop

class TAG-AF21

  set dscp af21

class TAG-AF11

  set dscp af11

class class-default

  set dscp default

!

On R2's serial interface I'm seeing policy-map drops from the SERIAL-QOS-INBOUND police cir 512000 statement.  This is video traffic. 

I'm just confused about inbound vs outbound.  From the perspective of R2, if I see inbound policy-map drops, does that mean the video is coming from LAN1 (or elsewhere on the WAN) and into LAN2? 

Thanks

Yes.

In vs. out on policies is like in vs. out on ACLs.
