Outgoing Priority queing on a 2800 and traffic shape.

I have configured priority queing on an outging Fastethernet interface on a 2800.

It is connected to an ethernet interface that has a max speed of 8Mb.

I want the priority mechanism to start working as soon as the outgoing traffic hist 7,9Mb (or 7 Mb) I thought the traffic shape command would work, but it does not. How must I do that?

Thanks

Re: Outgoing Priority queing on a 2800 and traffic shape.

Congestion management mechanims only work when the interface is actually congested. However, you can configure shaping to limit the traffic you send out the interface.

If you could provide more detail on exactly what you want to do we can help you better..,

Hope that helps - pls rate the post if it does.

I have the 2800 connected to an 8Mb Ethernet Internet line. What I want is the following: As soon as the outgoinh interface reaches 8Mb FTP, FTP-DATA and SMTP should be put in a low prio queue, DNS requests should be in a high queu. And alos some of the VPN connections should get a high priority.

Ok, what you need is a hierarchical policy that shapes at the parent level and prioritises at the child level:

For example,

policy-map shaper

class class-default

shape average 8000000

!

policy-map prioritiser

class VPN

priority

class DNS

bandwidth

class FTP_SMTP

bandwidth

!

interface FastEthernet0

service-policy output shaper

Pls remember to rate posts.
