Configuring Junos Os Ezqos For Cos (Cli Procedure) - Juniper JUNOS OS 10.4 - FOR EX REV 1 Manual

Table 459: Assigning CoS Components to Logical Interfaces (continued)
Field Function
Rewrite Rules Allows you to alter the CoS values in outgoing packets to
meet the requirements of the targeted peer. A rewrite rule
examines the forwarding class and loss priority of a packet
and sets its bits to a corresponding value specified in the
rule.

Configuring Junos OS EZQoS for CoS (CLI Procedure)

You use Junos OS 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:
Load the EZQoS configuration file (
1.
[edit]
user@switch# load merge /etc/config/ezqos-voip.conf
Apply the EZQoS group (
2.
[edit]
user@switch# set apply-groups ezqos-voip
Apply the DSCP classifier (
3.
( ge-0/0/0 ):
[edit class-of-service interfaces]
user@switch# set ge-0/0/0 unit 0 classifiers dscp ezqos-dscp-classifier
Apply the scheduler map (
4.
( ge-0/0/1 ):
[edit class-of-service interfaces]
user@switch# set ge-0/0/1 scheduler-map ezqos-voip-sched-maps
Your Action
To assign rewrite rules to the interface, select the
appropriate rewrite rule for each CoS value type
used on the interface.
