Can anyone explain what is the usage/scenario to apply per-port per-vlan?
What type of switchport that would be benefit when we apply per-port
per-vlan?

RE: Per-Port Per-VLAN marking
The per-port per-VLAN QoS feature enables you to specify different QoS
configurations on different VLANs on a given interface. You will need
to embed your class-map that mathches all in your class map that matches
the vlan, such as
access-list 1 permit any
class-map match-all ANY
match access-group 1
!
class-map match-all VLAN
match vlan 5
match class-map ANY
!
policy-map VLAN_IP
class VLAN
set precedence 4

Subject: Per-Port Per-VLAN marking
Hi all,
I had the following challange...
On a switch (3550) mark all incoming traffic from VLAN x with precedence
4
As I understand I should use per-port per-vlan marking
Right now I configure
class-map match-all PREC4
match vlan X
policy-map PREC
class PREC4
set ip precedence 4
when I apply this policy-map to a interface on a switch assume fa0/6 the
map would be rejected because I need another one more statement under
class-map config. This is what I understand.
So I configure an access-list 101 and with match access-group I apply it
as an additional statement into the class map
But right now I'm not sure if this really works...
Maybe anyone here had anything like this configured an can send an
example ??!
thanks
Udo
