Hi,

What's your current QoS policy? Is the link usage over 75% when your video is degraded?

Regards,

Elyinn.-

Hi

did u mean the link terminated on the on the CE router connected to PE?

how to check the Link Utilisation?

what is the best configuration on both site to let the video didint degraded

thanks

Hi Jamil,

To better help you, do you currently have any QoS policy implemented between the two sites? Do you have any SLA with the ISP? Use show interface serial x/x and look at the "reliability 255/255, txload 1/255, rxload 1/255" section to determine the usage.

You can use SolarWinds via SNMP to graph the utilization of the interface and it gives you a more accurate idea of your usage.

Regards,

Elyinn.

NOTE: If you don't have any QoS policy implemented, that's one of your issues. What kind of routers do you have, can you please explain your topology that way we can help you solve your problem much faster.

Hi

Plaese have a look to the attachment,no QoS Implemented,al looking to configure one...

no SLA between mine and providor

do have a show interface with congested parameters?

thanks

Before you get started, Have a chat with your MPLS provider.

1. What is their policy regarding traffic management, how do they handle marked traffic ?

2. What options do they offer for QOS in their cloud ?

     a. This is specific to at least one US provider, but the service offerings for mpls come in a variety of QOS options, what ever you do needs

         to be close to what your provider does. If the provider only guarantees 50% bandwidth for a certain class, you need to know that a head of time.

Hi

can u post a Public config regarding my situation then apply it with parameters used by ISP

Thanks

Hi,

Here's a Three Class MPLS Configuration I use with some customers.

This will NOT WORK if you don't have any formal agreements with your ISP!
