QoS - (Classification Question)

[JohnTylerPearce]

Hey Guys,

This is going to sound like such a stupid question. If I have a L2 switch, can I configure an access list based off of an ACL, such as

ip access-list extended QoSExample

permit tcp 10.0.0.0 0.0.0.255 any eq 80

And police based upon that, and or mark traffic at the port level?

Would the switch be able to classify the traffic, if it comes into the port as a frame and not a packet. (Granted it would be encapsulated)

It depends on the switch.  Pure L2 switches normally can't examine any L3 info.  L2+, smart or enhanced L2 switches often can.

Thanks for the help Joseph. I figured that was the case, I was just double-checking.
