DSCP 46 is universally understood to be the marking for EF (high priority, real-time) traffic. It's this command that designates a queue as a priority queue: Cisco IOS Quality of Service Solutions Command Reference - N through P [Support] - Cisco

A CoS or IP Prec of 5 can be Packet with a DSCP of any value from 40 - 47. and since 47 is reserved (unused) the highest at the level would be 46 (EF). So I guess your friend expected that the PAcket would have IP Prec of 5 and an DCSP of 40 - 46.

Jul 20, 2023 · When a router receives a packet with a DSCP value, the router applies the forwarding behavior associated with that DSCP value. The recommended DSCP value for EF is 101110. A packet that is marked with 101110 receives guaranteed low-drop precedence. 101110 in decimal is 46. Thank you

The traffic leaves with the same CoS and DSCP values as it enters. All the traffic, which includes voice, are delivered on the best effort basis. Switch# show mls qos. QoS is disabled. QoS ip packet dscp rewrite is enabled !--- Even though it says QoS ip packet dscp rewrite is enabled, !--- the switch does not alter the DSCP label on the ...

rate-limit output dscp 46 512000 96000 192000 confirm-action transmit exceed-action drop . you can apply a second rate-limt command for the best effort traffic. int g0/1. rate-limit output dscp 46 512000 96000 192000 confirm-action transmit exceed-action drop. rate-limit output dscp 0 1024000 192000 384000 confirm-action transmit exceed-action drop

Ayoola, Policing as I read has the option to transmit if exceed-acction is met by remarking the DSCP value . E.g police 100000000 8000 exceed-action policed-dscp-transmit ====this will not drop packet but dscp code will change. For this to happen I have to define it using global configuration = mls qos map policed-dscp 46 to 26

DSCP and IP Precedence represent a view of the same field within the IP Header. CoS is an 802.1p field in ethernet (L2) extend has to do with a connected device. DSCP covers the ToS field in IP. DSCP has names for things that overlap the IP Precedence markings. IP Prec was 3 bits. DSCP is 6 bits, which includes the 3 bits from IP Prec.

mls qos map policed-dscp 0 24 to 8 . My understanding of this command is to mark down DSCP values 0 and 24 to a new DSCP value of 8. Now, as far as i know, DSCP 24 is equal to CS3, the default value for call signalling traffic in our network. My question to you is, does this command only take affect if traffic policing is enabled on an interface?

mls qos cos-dscp 0 8 16 24(26) 32 46 48 56 . The old wireless mapping mls qos cos-dscp 0 10 18 26 34 46 48 56 may cause strange thinks in my eyes. In my opionen in the voice-deployments guides is the end-to-end-qos missing, but we have to handle with it.
