Help with QOS

Hi,

We have 2MB circuit to the US that gets flooded every night by a specfic machine. I want to appy a QOS policy that defines this machine and reduces its priority so that when the link becomes saturated the traffic is discarded.

Any help well rated.

Thanks

Gavin

Re: Help with QOS

I would apply policing to discard that traffic.

First define an ACL that permits all ip traffic from that specific machine.

access-list 101 permit ip x.x.x.x 0.0.0.0 (host machine) any

next define a class-map that identifies the ACL we did previously.

class-map POLICE_TRAFFIC

match access group 101

then define the policy-map to police that traffic.

policy-map POLICE

class POLICE_TRAFFIC

police x (threshold were if traffic exceeds x it will be dropped)

then apply the policy map to the outgoing interface.

service-policy POLICE out

More information on policing is on the link below.
