Hi all..Once again but with diff case.
I have two locations DC & DR connected with two lease line 45+45 Mb.Also configure EIGRP betw these two location for load balancing.
Q. I have one NAS at DC and other replica of that NAS is at DR.High volume of data is transfring betw these server.
I want to configure QOS like 50% of the bw use for two NAS server and 50% for other traffic.
What steps need to be configure for acheiving this............Thanx...

What kind of devices, and their IOS version, connect to the DS3s?

Hi Arjun,
There are only few steps to configure the QOS :
1. configure a access list for your NAS server
2. Call that access-list into Class-map.
3. Configure a policy map which can fulfil your requirement of allocation of 50% Bw to that server at any point of time.
4. Apply that policy map to wan interfaces.
May be you will having metroethernet or ethernet connectivity on your end from Service provider.
Ex:
ip access list standard NAS_Server
permit x.x.x.x 0.0.0.0
Class-map match-all NAS
match access-group NAS_Server
policy-map BW_MG
class NAS
bandwidth percent 50
class class-default
fair-queue
exit
apply this cmd on WAN interface
service-policy output BW_MG
show policy-map int fa0/
Try this It should work

Hi,
Thanx for ur reply...
I have one doubt...On which wan interface i have apply service-policy? B'cause on my router i have two wan interface which are in eigrp for load balancing.
I want to assign 50%(45+45=90MB) of bandwidth to NAS.
is it possible?
Thanx...

on both interfaces,Try it....

Thanx.......
I'll try.
Is it require to configure on both router DC and DR?

But when i send some icmp traffic, it shows only on one interface.

It is ok, Plz check he access-list & make it sure it is correct.
