Hi Guys,
I'm configuring my router to guaranteed minimum bandwidth of 512K for all traffic leaving E0/0 of R3 with IP Precedence 2.
solution I:
On R3
class-map match-all Pr2
match input-interface Ethernet0/0
match ip precedence 2
policy-map P1
class Pr2
bandwidth 512
interface Ethernet0/0
service-policy output P1
solution II:
on R3
all config the same except match precedence 2 instead of match ip precedence 2.
what's the diffrence between both statements!!
--> match ip precedence 2
--> match precedence 2
which solution is the most correct !!
appreciate any helpful inputs..

match precedence = matches both IPv4 & IPv6 packets
match ip precedence = matches IPv4 packets only.
One other thing. If you are matching traffic leaving e0/0 why the "match input-interface e0/0" ?

Hi Jon,
it make scenes now, do u thing "match input-interface e0/0" command isn't required to achieve the goal !!

Belal,
You are trying to use congestion management method and the policy is applied to the e0/0 interface for doing outbound queuing. It's not properly to match inbound packets from the e0/0 interface.
Note: If the interface doesn't get congestion then the policy will not be applied.It's not easy to make the ethernetinterface to get congestion.Seems you need to use shaping and child-policy to beat this requirement.

Hi Thot,
u r right It's not easy to make the ethernet interface to get congestion but I just configured it for testing purpose to figure out if this is only required config commands to achieve the requirement.
it seems as u had said no need to match the physical interface.
many thx..
