TitleWhat are the Basic Details on CoS, DSCP and map Settings for the 800-Series?
Question
1. Does the 800 series honor DSCP priority by default?
 
2. What are the 802.1p Map Settings/ DCSP Map settings; what does the color option allow you to do?

3. Is it possible to map the DSCP priority to CoS priority and have the 802.1p applied to packets based on the DSCP value
Environment
  • 800-series
  • All Firmware
Answer
1.  No - the ports must be put in trust mode.
 
2. See “show config effective include "dscp" or see the manual
