Hi,
Need a help on prioritizing traffic/QoS/Bandwidth allocation.
I have a branch office connected to 1 Mbps MPLS link. (LAN: 10.200.10.0/24)
Users in branch office access applications hosted in Head Office. We have two types of applications:
1. Critical Applications (Destination IP: 10.128.0.0/24) - ERP
2. Non-Critical Applications (Destination IP: 10.130.0.0/24) - Email & Virus Guard Push Update
In current setup, branch office link bandwidth is fully utilized for non-critical application access. This makes performance issue for critical application access.
I intent to limit bandwidth in congestion state. Like maximum 0.4 Mbps (40%) for non-critical applications.
Minimum 0.6 Mbps (60%) for critical-applications.
MPLS link is connected to F0/1 in branch CPE. I have access only to branch CPE router.
Please help me with sample configuration.

Hello,
the below should work. That said, a 1MB link is really on the extremely low side. Obviously I don't know how heavily the link is being utilized, but 1MB might get saturated really fast. Either way, here is the config:
access-list 101 permit ip 10.200.10.0 0.0.0.255 10.128.0.0 0.0.0.255
access-list 102 permit ip 10.200.10.0 0.0.0.255 10.130.0.0 0.0.0.255
!
class-map match-all LAN_CRITICAL
match access-group 101
!
class-map match-all LAN_NON_CRITICAL
match access-group 102
!
policy-map BRANCH_TO_HO
class LAN_CRITCAL
bandwidth 600
class LAN_NON_CRITCAL
bandwidth 400
class class-default
!
interface FastEthernet0/1
service-policy output BRANCH_TO_HO

Hi
Additional to Georg's comment, there are 2 ways to handle the bandwidth, using: police o shape, the following link could be useful as well. Is good to know they have some differences how they control the traffic.

Have a nice new year
