QoS Classification on Cisco IOS Router

Hello Rarylson

Thanks for sharing your results! I’ve created a NetworkLessons note on the subject for future reference.

Thanks again!


hi @ReneMolenaar

having a bandwidth of 90 Mbps.

Having two LAN POOL: DATA: & VC:

90 Mbps of Bandwidth is overutilized by DATA Pool.

Need to configure Priority Bandwidth if VC is connected then 30Mbps must be used for VC Network & 60Mbps for DATA Network.
If VC Traffic is not established, then DATA Pool can use of 90 Mbps.

Highly appreciate it if you will help in that case.

Hello Pratik

From what I understand, you have an interface with a bandwidth of 90 Mbps, and you want to reserve 30 Mbps for use with VC. This can be achieved using queuing and classification. If you classify your packets coming from the VC LAN, you can then apply the bandwidths you want to that traffic. Take a look at this lesson that describes how it can be done:

Queueing prioritizes traffic and can ensure that your VC traffic will have guaranteed bandwidth even under the most congested situations.

Take a look at this and if you have more questions about it, let us know!

I hope this has been helpful!



We attempted this, but the router does not support a few commands.

Priority base bandwidth allocations are desired. Like voice (25%), video (25%), and default (50%), for inbound and outbound.
If voice and video are not used, then 100% must be used.

Hello Pratik

Can you let us know a little bit more about your specific implementation? What platform and IOS are you using? Have you checked Cisco’s feature navigator to see if your platform/IOS combination supports the appropriate QoS features that you’re trying to employ?

Let us know so that we can help you further!

I hope this has been helpful!
