Hello MT Community,
I have questions about the Level-2 prioritization Priority Code Point (PCP), Drop Eligible Indicator (DEI) and Level-3 Differentiated services Code Point (DSCP) implementation and interactions on CRS.
-
On CRS112 how do I set a default PCP on all (except ether1 which is a master and trunk port) ports? Do I achieve it through /interface ethernet switch port default-customer-pcp or do I set it through /interface ethernet switch acl new-customer-pcp? The ports have Ingress-VLAN-Translation.
-
Do I enable pcp-or-dscp-based-qos-change-dei and pcp-or-dscp-based-qos-change-pcp in /interface ethernet switch port so that routers and switches are aware of Level3 protocol DSCP (Video and VoIP applications) which may change the default PCP? What additional settings for mapping should I do, if necessary?
-
What additional settings on the router CCR1009 shall I adjest so that VoIP and Video are prioritized to/from WAN and the internal network?
Thank you for your help and advises.
