qos pre-classify

Hello,

I understand the principle of the QOS preclassify okay. However, I have one area of concern. You place the qos preclassify command at the crypto map level and the serice policy to orioritise the traffic at the interface level.

My question? Will traffic that DOES NOT match the encryption access lists still be prioritised by the service policy? I would have thought so since traffic that does not match the access lists goes through the interface as normal.....?????

Re: qos pre-classify

Correct, if the traffic is not encrypted it'll hit the service-policy just like any other standard traffic.

The "qos pre-classify" just says take a snapshot of the original packet BEFORE we encrypt it so that we can apply the same service-policy to it, even though it's already encrypted by that time.
