Bandwidth Limit for per host

[prabhakarant1991]

Dear Team

My Head is connected to Branch Office using MPLS.

Head Office Backbone 25Mbps then Branch Office 2Mbps 

Per Host Ip address bandwidth limit how to passable

Head Office subnet 172.16.0.0/21

Branch Office Subnet 172.16.88.0/21

Branch Office System details for 50 nos desktop connected to mpls line

I want to limit the traffic from a BO host y.y.y.y to my HO server x.x.x.x.

Thanks in advance.

Prabhu.

Hello
 

You dont state what amount of BW you would like to specify for this specifc host - I have applied a 0.5mb limit in this example.

LAN - Police inbound on Lan interface for specific host traffic to 512kbs (0.5mb)

access-list 100 permit ip host 1.1.1.1 host 2.2.2.2

class-map match-all BO-HOST_cm
 match access-group 100

policy-map Police-BO-HOST_pm
 class BO-HOST_cm
  police 512000 conform-action transmit  exceed-action drop

interface x/x
 description LAN interface
 service-policy input Police-BO-HOST_pm

WAN -  Apply LLQ to speciifc host traffic and traffic shape wan cir to 2MB

policy-map WAN-Child_pm
 class BO-HOST_cm
  priority 512
 class class-default
  fair-queue

policy-map WAN-Parent_pm
 class class-default
  shape average 2048000
  service-policy WAN-Child_pm

interface x/x
 description WAN interface
service-policy output WAN-Parent_pm

You could police or shape traffic to just that host pair, but both limit bandwidth even when more is available.  For internal usage, setting aside bandwidth ratios is often a better solution.  For example, you might set aside an allowance of 50% of your 2 Mbps for your server to server traffic.  If there's other bandwidth, the pair would only get 1 Mbps, but if there's more bandwidth available, they could use it.
