Configuring JUNOS EZQoS for CoS (CLI Procedure)

You use JUNOS EZQoS on EX-series switches to eliminate the complexities involved in configuring class of service (CoS) across the network. EZQoS offers templates for key traffic classes.

When you configure EZQoS on EX-series switches, preconfigured values are assigned to all CoS parameters based on the typical application requirements. These preconfigured values are stored in a template with a unique name.

Note: Currently, we provide an EZQoS template for configuring CoS for VoIP applications. The EZQoS VoIP template is stored in /etc/config/ezqos-voip.conf.

To configure EZQoS using the CLI:

1. Load the EZQoS configuration file (/etc/config/ezqos-voip.conf):
   
   

   [edit]
user@switch# load merge /etc/config/ezqos-voip.conf
2. Apply the EZQoS group (ezqos-voip):
   
   

   [edit]
user@switch# set apply-groups ezqos-voip
3. Apply the DSCP classifier (ezqos-dscp-classifier) to a Gigabit Ethernet interface (ge-0/0/0):
   
   

   [edit class-of-service interfaces]
user@switch# set ge-0/0/0 unit 0 classifiers dscp ezqos-dscp-classifier
4. Apply the scheduler map (ezqos-voip-sched-maps) to a Gigabit Ethernet interface (ge-0/0/1):
   
   

   [edit class-of-service interfaces]
user@switch# set ge-0/0/1 scheduler-map ezqos-voip-sched-maps
