QoS: restrict TCP IP:80 traffic to a lower priority

[Bruno Dinis]

Hello everyone..

I have some issues in my company in some offices about 20km from the Headquarters..they are always complaining about the "network speed" although I'm sure its only the Internet traffic..

I've implemented qos to voice traffic be the first priority in the connection, although I need to put tcp ip traffic: 80 (internet basically) in a lowest level at all..

Is this possible?

i've a cisco 2821 router in the office and 7206 VXR in the headquarters.

~cheers

Hi,

yes of course you could police web traffic to a very low speed.

just match traffic in a class-map and under policy-map for this class as action choose police then apply this policy either inbound on your LAN or outbound on the WAN.

As Alain noted, it's possible.

However, when you deprioritize HTTP traffic, you might want to check it's just Internet traffic.  Now a days, lots of internal traffic might be using that protocol tool.

Also, you didn't describe your current policy.  I've found "basic" FQ will handle 90% of most routine QoS needs.  If you have real-time traffic like VoIP, class-default FQ and LLQ handle the other 9%.  If you're down to the 1%, then you can define very extensive policies to control your traffic, but at this level of control, you really need to understand how various policy settings interact with different traffic types.
