Hi Naresh, we do support DSCP and also 802.1p. This article in the Cumulus Linux user guide should help:

Hi Pete,

Thanks for the reply. Let me explain use case I am looking for. Say, if a packet with dscp 40 reaches cumulus switch on port 1 and supposed to go out of port 2 based on routing protocol, BUT can we have any rule such that, I can classify this packet for dscp 40 and write rule to send to port 3 instead?

We would like to do policy based routing based on matching DSCP or IP address. Can you please let me know cumulus supports it?

Thanks & Regards
Naresh

Cumulus Linux does not support PBR (Policy Based Routing) yet. We may in the future. Please email sales@cumulusnetworks.com for questions about road maps.
Hi.
Since this thread was done 1 year and a half ago, does PBR still not supported ?

Hello,
Does latest version 3.3 support PBR yet?
or should I using Quagga instead?

Thanks!

Not yet. Quagga would be a better choice in general. I have always thought of PBR as a way to handle temporary exceptions to the routing design. It carries too much overhead in terms of resource utilization and operational maintenance. Always best to go with a deterministic routing design.
