QoS based on DSCP marking

yikching — Wed, 12 Nov 2014 02:13:46 GMT

We have Mitel IP phone systems deployed across multiple IPsec VPN sites

The voice packets are marked EF (DSCP 46) and signalling packets are marked AF31 (DSCP 26) automatically by the IP phones and PBX.

Under QoS policies, there doesn't seem to be a way to classify traffic into PAN QoS based on DSCP marking.

Assuming that QoS classification using source/destination IP (some sites have data/voice devices in the same subnet) and application/port range (random RTP ports) isn't an option, can anybody advice what are other ways are possible?

Thanks!

Hi Yik,

PANW doesnt honor DSCP marking forwarded from upstream. For more information refer following article.

DSCP Honoring

We have a open FR for the same, please ask your SE to vote on your behalf.

Priority: Low
