Should I trust COS or DSCP

Postby admin » Tue Mar 20, 2012 12:33 pm

To prevent your markings from being stripped by an access port or an Untrusted port, always mark and trust DSCP, COS values could be stripped.

Set your Trunk ports to Trust DSCP. You also need to configure your COS-DSCP mappings for your switches to correctly prioritize traffic through the switch.

Always trust COS when connecting to a Cisco Wireless LAN Controller, they cannot mark DSCP.
Always trust DSCP when connecting to a Cisco Wireless Access Point if they are connected with an Access Port.
