IP precedence CS1 vs. dscp af11
Which one is higher in the hierarchy, which marking will be given priority / processed first?
With dscp AF11, 12, 13
I believe that af11 will be processed first, having a lower drop priority.
AF11 has a decimal value of 10, AF12 of 12 and AF13 a decimal value of 14.
Even though the decimal values increase, higher values (within the class) mean more likely to be dropped.
Of course, AF21 will have a decimal representation of 18 and there the logic restores itself as AF21 is given higher priority than AF1x.
My question is this, if within a class, lower is better, does that mean that an ip precedence value of CS1 is given preferential treatment (having a decimal representation of 8)? How exactly do the IP precedence / dscp csales stack up against each other? (apart from being compatible, that is)
In theory, CS1 should be treated as higher than AF11. AF11 would be closer to CS1. That being said, your QoS policies can be configured to do whatever you want so your switch may be configured to drop CS1 way before it drops AF11.
