Modify QoS Profile on interface based on schedule?

Mack — Tue, 06 Sep 2011 19:57:04 GMT

Hi all,

I'm wondering if there's a way to have a different QoS profile applied to an interface based on a schedule? We want to be able to set different guaranteed egress and maximum egress values to the QoS classes based on time of day. From what I can see, there can only be one QoS profile set per interface and there appears to be no way to have that change via a schedule. The dynamic changes I can see is that we can use a schedule-based QoS Policy to change which class traffic is assigned into, but I want to change the bandwidth allocations on the classes themselves. Any ideas?

Hi,

It is not supported, and as you mentioned you can only use different class based on schedule by configuring the QoS policy.

I know it's not supported as a mechanism in the OS, I was more looking to see if anyone had come up with a clever workaround. For instance, things I've thought of exploring:

* Path Based Forwarding on a schedule, sending traffic through different interfaces based on time of day where each interface has a different QoS Profile

* using a script to connect over SSH and issue CLI changes to the QoS Profile at the appropriate time of day
