IP Surveillance QoS configuration

[burleyman]

I am looking for some conformation / guidance on some QoS configuration.

I have attached a diagram of the network example for what I am looking to do.

I am looking at configuring QoS for IP Surveillance through a network. Now because the IP Camera I am using does not have a place to configure QoS DSCP settings I am doing it on the switchport. So I will set the CoS to 5 for that. Next I need to trust the CoS value on the trunk uplinks between the switches so I will configure those ports to Trust the CoS value. Next on the link to the server I will set the CoS value there just like I do on the IP Cameras for the video playback to the viewing stations. I was thinking I would need to set the CoS value on the ports connected to the Viewing stations but I am now thinking I do not need to do that because the traffic going to the station not coming from the station, am I correct in my thinking here?

I used this as a reference.

Here is what I am looking to configure.

IP Surveillance QOS setup

**************************************

Enable QOS on IDF and MDF switches

config t

mls qos

**************************************

Configure switchport for Camera

config t

int gix/x or gix/x/x

description IP Surveillance Camera

switchport mode access

switchport access vlan 45

mls qos cos 5

spanning-tree portfast

no shut

************************************

Configure trunk uplinks between switches

Do this on each side of the uplink.

config t

int gix/x or gix/x/x

mls qos trust ip-precedence

I would do exactly what you have done.

One more configuration. For the servers where the video is stored and viewed from I was going to configure this. Goal of this is to give priority to traffic for the video viewing and mark that as CS5 and all other traffic like the control type traffic from the server marked as CS3.

class-map match-all VIEW_HTTP

   match access-group name HTTP

Policy-map NVR

   class VIEW_HTTP

      set dscp cs5

   class class-default

      set dscp cs3

ip access-list extended HTTP

   permit tcp any eq www any

Then on the interface where the server is connected.

interface gi1/0/1

   description NVR Server

   switchport mode access

   switchport access vlan 45

   priority-queue out

   spanning-tree portfast

   service-policy input NVR

Thanks,

Mike

Looks good to me.
