MetroEthernet Link Management (QoS)

[Andres Franco]

Hello everyone.

I've the following case:

An ISP is providing a 20 MB MetroEthernet link to a client. The router has the configuration of this in a GE subinterface.  There is not QoS, only the basic config. Althought there is enough bandwidth, Intenernet surfing is slow. How could I apply QoS to this MetroEthernet subinterface to optimize traffic passing through it?? how could i define bandwidth percentage usafe for WWW and other types of traffic to improve network performance?? Thanks.

Hi Andres,

To investigate the congestion lead, the following link should help: http://www.cisco.com/en/US/partner/docs/ios/qos/configuration/guide/congstion_mgmt_oview_ps6350_TSD_Products_Configuration_Guide_Chapter.html

Thank you Laurent. Is there another way to do this? (I´ve already read about queing tecniques). Could you provide an example of config?. Thanks again.

Hi Andres,

You need to use Hierarchical QoS as you have less than the physical BW available (20M instead of 1G).

The following link will give you a detailed description about this feature and its implementation
