Cisco QoS – Four CoS Levels

Work with your provider to find out what options you have. It’s critical that you match DSCP Names/Values with what they have configured or else it won’t work. You can’t just turn it on and it works like some people think. Below was an option from one of our providers:

CoS Level= DSCP Names | DSCP Values
———————————————————————————————————————————————————-
Interactive Voice ~ premium plus (35%)= CS5,EF|40,46
Critical Data ~ Enhanced Plus (25%)= CS3,AF31,AF32,AF33,CS6,CS7|24,26,28,30,48,56
Preferred Data ~ Enhanced (15%)= CS2,AF21,AF22,AF23|16,18,20,22
Default ~ Basic Plus (25%)= CS1,AF11,AF12,AF13,All Remaining Traffic|1-15,17,19,21,23,25,27,29,31,33,35,37,39,41-45,49-55,57-63

So now if I want to throw something together, it would look like this:

ip access-list extended CRITICAL-APPS_ACL :A nice ACL to prioritize critical applications
remark Critical Apps Subnet 1
permit ip any 172.21.2.0 0.0.0.255
remark Critical Apps Subnet 2
permit ip any 172.24.1.0 0.0.0.255

class-map match-any INTERACTIVE-VOICE :Voice is Voice and always need to be the highest prioritized
match ip dscp ef

class-map match-any CRITICAL-DATA :Here's where you need to do some homework and find out what's critical in your environment and put it here
match protocol sip
match protocol citrix
match protocol bgp
match access-group name CRITICAL-APPS_ACL
match ip dscp cs3
match ip dscp af31

class-map match-any PREFERRED-DATA :SSH was put here so that the IT staff can still have remote access to their devices to help troubleshoot
match protocol ssh

policy-map WAN_QOS
class INTERACTIVE-VOICE
priority percent 35

class CRITICAL-DATA
bandwidth percent 25
set ip dscp af31

class PREFERRED-DATA
bandwidth percent 15
set ip dscp cs2

class class-default
bandwidth percent 25
fair-queue
random-detect

interface gigx/x
service-policy output WAN_QOS

Again this is just an example but you can customize it to fit your environment. Try to follow best practices when you can. Below is a snapshot of Cisco’s best practices:

Cisco QoS Best Practices

You can see for Network Mgmt they recommend CS2 and above we have SSH set to CS2 in Preferred Data since that’s where CS2 belongs (look at the SP’s settings). Routing is CS6 in Cisco’s documentation which falls under Critical Data, so we placed BGP in Critical Data but we are tagging it with AF31.

One thing to keep in mind is that difference values at the same level of CoS can have a difference Drop Probability. See below:

Cisco DCSP Values
Cisco Precedence Values

Above you’ll notice I’m using NBAR options to help match specific traffic by protocols. Below are all the options on the router I was using. There are a lot.
