Traffic Shaping or Traffic Policing (Rate Limiting)

[kfarrington]

I have a request and I will simplyfy it below :)

SCENARIO :-

I have a router and two LANs. Host-a on LANa sends too much traffic to a server-b on LANb. The two LANs have other client/server apps which are suffering because of of the host-a/server-b traffic. I need to reseve some bandwidth for the host-a/server-b traffic so other client/server users do not get impacted buy the host-a/server-b traffic.

LAN is 100MB and I want to rate the traffic to 10MB. The traffic is not time critical and we dont care if a transfer between them take 10 minutes or 10 hours.

QUESTION :-

Should I use Traffic Shaping or Traffic Policing (Rate-Limiting) to acheive my goal?

Many thx indeed,

Ken

In this case i would prefer traffic shaping as it doen no drop packets but delay's them.

but wouldnt it be nicer to use qos as this could give the server full bandwith if there is no other traffic.

Hi,

I hope the following config will fulfil your requirment.

Router(config)#access-list 101 permit ip host host

Router((config)#class-map

Router((config-cmap)#match access-group 101

Router((config-cmap)#exit

Router((config)#policy-map

Router((config-pmap)#class QOS

Router((config-pmap-c)#bandwidth percent 10

Router((config-pmap)#class class-default

Router((config-pmap-c)#fair-queue

Router((config-if)#service-policy output QOS

You need to apply this service-policy in both ethernet interface.
