IEEE 802.1p behavior aggregate (BA) classifiers to determine the forwarding treatment for packets entering the device. Note that only IEEE 802.1p BA classifier types are supported on devices operating in transparent mode. Rewrite rules to redefine IEEE 802.1 CoS values in outgoing packets

Define a CoS behavior aggregate (BA) classifier for classifying packets. You can associate the classifier with a forwarding class or code-point mapping, and import a default classifier …

A Junos OS classifier identifies and separates traffic flows and provides the means to prioritize traffic later in the class-of-service (CoS) process. A behavior aggregate (BA) classifier performs this function by associating well-known CoS values with forwarding classes and loss priorities

Classifiers associate packets with a forwarding class and loss priority and assign packets to output queues based on the associated forwarding class. Junos OS supports two general types of classifiers: Behavior aggregate (BA) classifier—Examine the CoS value in the packet header

Junos OS provides a range of default BA classifiers that you can apply to logical interfaces and that map various CoS values to assured-forwarding and expedited-forwarding forwarding classes as well as to the best-effort and network-control forwarding classes

On Juniper Networks devices, you configure CoS functions using different CoS-related components, such as BA classifiers, schedulers, rewrite-rules etc. Aside of this, some CoS functions may also be configured using firewall filters (e.g. MF classification)

Traffic entering a Juniper router (M, MX & T Series) or firewall (J-Series and SRX) will be classified in the following order: Packet is first classified based on BA classifier and code-points. Next packet is checked for any MF classifiers. If one exists it overrides the BA classifier and sends the packet to the queue as defined in MF classifier

Classifiers. These observe DSCP, Inet Precedence or other marker types to assign ingress traffic to forwarding classes. JunOS comes with a default classifier for each type of classification (DSCP, MPLS, Inet Precedence, etc.). On a private network which you control, this is my preferred way of doing it

May 22, 2011 · If the value of an alias changes, it alters the behavior of any classifier that references that alias. The table below shows the default mappings between the bit values and standard aliases. For example, it is widely accepted that the alias for DSCP 101110 is ef (expedited forwarding)

May 22, 2017 · https://www.juniper.net/documentation/en_US/junos/topics/concept/classifier-ba-overview-cos-config-guide.html The BA classifier looks at specific bit field in the incoming packet, and maps a CoS value in the packet header to a forwarding class and loss priority so the acket can be further processed. The forwarding class determines the output queue

Unlike Cisco, Juniper does not support a shape command that queues the traffic by default. You have to build this functionality manually. From Packet entering the router to the packet leaving the router these are the CoS steps that are taken: ... Enter packet -> BA Classifier (sets forwarding class, loss priority) -> Multifield Classifier (can

Junos Fusion provides a method of significantly expanding the number of available network interfaces on an aggregation device by allowing the aggregation device to add interfaces through interconnections with satellite devices. The entire system—the interconnected aggregation device and satellite devices—is called Junos Fusion. Junos Fusion simplifies network administration by appearing in

Sep 14, 2017 · The first thing to know is that Juniper call it Class of Service (CoS). In Cisco land, the term ‘CoS’ is used exclusively for layer 2 (802.1q) QoS, so this can be confusing initially. As with my other Juniper posts, the configuration will be for an MX104 router
