Table 6-1 lists the commonly used DSCP values described in RFC 2475. Table 6-2 lists the RFC 791 precedence values from least to most important. Flash - mainly used for Voice Signaling or for Video. Critical -mainly used for Voice RTP.

Differentiated services or DiffServ is a computer networking architecture that specifies a mechanism for classifying and managing network traffic and providing quality of service (QoS) on modern IP networks.

Jun 5, 2015 · I am looking packets DSCP value on an access layer switch using the command 'show mls qos int stat'. I'm seeing packets CS6 from the switch to the phone. Any idea what packets are getting sent to the phone?

Sep 5, 2024 · This document describes how to set the Differentiated Services Code Point (DSCP) values in Quality of Service (QoS) configurations on a Cisco router.

Nov 15, 2024 · The Differentiated Services (Diffserv) architecture specifies use of the DS field in the IPv4 and IPv6 packet headers to carry one of 64 distict differentiated services field codepoint (DSCP) values.

Apr 19, 2022 · DSCP Marking is a CLI-controlled feature, which enables to create and map 5QI and ARP values to enforceable QoS parameters. The SMF sends the configured DSCP value to the UPF. Then, the UPF applies the DSCP marking on the uplink and downlink packets based on the 5QI and ARP.

Mar 13, 2017 · For example, packets with a DSCP value of `110000' (IP-precedence 110) have a preferential forwarding treatment (scheduling, queuing, etc.) as compared to packets with a DSCP value of `100000' (IP-precedence 100).

DSCP値により処理を決めることを PHB （Per Hop Behavior）と言います。 PHBごとのDSCP値は以下です。 上表のDefault、Class Selector、Assured Forwarding、Expedited Forwardingの意味は以下の通りです。 ベストエフォート で転送する。 優先しないPCのデータトラフィックに通常割り当てる。 IP Precedenceとの下位互換性。 例えばDSCP値40であるCS5は、IP Precedence5と同じ意味。 確認転送用のクラス。 4段階の優先度（先頭3bit：001、010 …

It is now called the "DS" (Differentiated Services) field and the upper 6 bits contain a value called the "DSCP" (Differentiated Services Code Point). Since RFC 3168, the remaining two bits (the two least siginficant bits) are used for Explicit Congestion Notification.

DSCP TOS CoS Precedence are all about prioritizing traffic ensuring the most important data gets through efficiently, even when the network is congested.
