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 :
3. voip
[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
4. network_control
[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 best_effort_traffic
5.
[edit firewall]
user@switch# set family ethernet-switching filter voip_class term best_effort_traffic
then forwarding-class best-effort loss-priority low
to classify the VoIP traffic:
voip_class
