To configure and apply CoS:
Configure one-to-one mapping between eight forwarding classes and eight queues:
1.
[edit class-of-service]
user@switch# set forwarding-classes class app queue-num 5
user@switch# set forwarding-classes class mail queue-num 1
user@switch# set forwarding-classes class db queue-num 2
user@switch# set forwarding-classes class erp queue-num 3
user@switch# set forwarding-classes class video queue-num 4
user@switch# set forwarding-classes class best-effort queue-num 0
user@switch# set forwarding-classes class voice queue-num 6
user@switch# set forwarding-classes class network-control queue-num 7
Define the firewall filter
2.
[edit firewall]
user@switch# set family ethernet-switching filter voip_class
Define the term :
voip
3.
[edit firewall]
user@switch# set family ethernet-switching filter voip_class term voip from
source-address 192.168.1.1/32
user@switch# set family ethernet-switching filter voip_class term voip from
source-address 192.168.1.2/32
user@switch# set family ethernet-switching filter voip_class term voip protocol udp
user@switch# set family ethernet-switching filter voip_class term voip source-port
2698
user@switch# set family ethernet-switching filter voip_class term voip then
forwarding-class voice loss-priority low
Define the term network_control
4.
[edit firewall]
user@switch# set family ethernet-switching filter voip_class term network_control from
precedence [net-control internet-control]
user@switch# set family ethernet-switching filter voip_class term network_control then
forwarding-class network-control loss-priority low
Define the term
5. best_effort_traffic
[edit firewall]
user@switch# set family ethernet-switching filter voip_class term best_effort_traffic
then forwarding-class best-effort loss-priority low
Apply the firewall filter
6.
phones:
[edit interfaces]
user@switch# set ge-0/0/0 description phone1–voip-ingress-port
user@switch# set ge-0/0/0 unit 0 family ethernet-switching filter input voip_class
user@switch# set ge-0/0/1 description phone2–voip-ingress-port
voip_class to classify the VoIP traffic:
:
with no match conditions:
as an input filter to the interfaces for the VoIP
