Ingress traffic shaping profile

A traffic shaping profile can be applied to an interface for traffic in the ingress direction. Similar to an egress traffic shaping profile, the guaranteed bandwidth and priority of the profile will be respected when an interface receives inbound traffic. When congestion occurs, any remaining bandwidth will be allotted to classes based on priority.

Example

In this example, the port2 interface has a total inbound bandwidth of 100 Mbps. Traffic from certain clients to certain servers are assigned different classes.

IPv6 traffic from any client PCs to server PCs is assigned class 5.

For each class, the priority, guaranteed bandwidth, and maximum bandwidth are as follows:

Class	Priority	Guaranteed bandwidth	Maximum bandwidth
2	Low	10%	60%
3	High	20%	100%
4	High	30%	100%
5	Medium	10%	50%

Bandwidth will first be allotted to each class according to its guaranteed bandwidth. Then remaining available bandwidth will be allotted to class 3 and 4 first based on their priority. The allocation will be proportional to their guaranteed bandwidth ratio.

To configure ingress traffic shaping:

1. Configure the client and server addresses:

   config firewall address
       edit "pc1"
           set subnet 10.1.100.11 255.255.255.255
       next
       edit "pc2"
           set subnet 10.1.100.22 255.255.255.255
       next
       edit "pc4"
           set subnet 172.16.200.44 255.255.255.255
       next
       edit "pc5"
           set subnet 172.16.200.55 255.255.255.255
       next
   end

2. Configure the class IDs:

   config firewall traffic-class
       edit 2
           set class-name "class2"
       next
       edit 3
           set class-name "class3"
       next
       edit 4
           set class-name "class4"
       next
       edit 4
           set class-name "class5"
       next
   end

3. Configure traffic shaping policies to assign classes to each group of traffic.
   1. Configure a policy to assign traffic from PC1 to PC4 in class 2:

      config firewall shaping-policy
          edit 1
              set name "shaping policy 1"
              set service "ALL"
              set dstintf "wan1"
              set class-id 2
              set srcaddr "pc1"
              set dstaddr "pc4"
          next
      end

   2. Configure a policy to assign traffic from PC2 to PC4 in class 3:

      config firewall shaping-policy
          edit 2
              set name "shaping policy 2"
              set service "ALL"
              set dstintf "wan1"
              set class-id 3
              set srcaddr "pc2"
              set dstaddr "pc4"
          next
      end

   3. Configure a policy to assign traffic from PC2 to PC5 in class 4:

      config firewall shaping-policy
          edit 3
              set name "shaping policy 3"
              set service "ALL"
              set dstintf "wan1"
              set class-id 4
              set srcaddr "pc2"
              set dstaddr "pc5"
          next
      end

   4. Configure a policy to assign all IPv6 traffic to class 5:

      config firewall shaping-policy
          edit 4
              set name "shaping policy 4"
              set ip-version 6
              set service "ALL"
              set dstintf "wan1"
              set class-id 5
              set srcaddr6 "all"
              set dstaddr6 "all"
          next
      end

4. Configure a shaping profile to set the priority, and the guaranteed and maximum bandwidth percentages for each class:

   config firewall shaping-profile
       edit "ingShapeProfile"
           set default-class-id 2
           config shaping-entries
               edit 2
                   set class-id 2
                   set priority low
                   set guaranteed-bandwidth-percentage 10
                   set maximum-bandwidth-percentage 60
               next
               edit 3
                   set class-id 3
                   set guaranteed-bandwidth-percentage 20
                   set maximum-bandwidth-percentage 100
               next
               edit 4
                   set class-id 4
                   set guaranteed-bandwidth-percentage 30
                   set maximum-bandwidth-percentage 100
               next
               edit 5
                   set class-id 5
                   set priority medium
                   set guaranteed-bandwidth-percentage 10
                   set maximum-bandwidth-percentage 50
               next
           end
       next
   end

5. Configure the inbandwidth and apply the ingress shaping profile on port2:

   config system interface
       edit "port2"
           set ip 10.1.100.1 255.255.255.0
           set inbandwidth 100000
           set ingress-shaping-profile "ingShapeProfile"
           config ipv6
               set ip6-address 2000:10:1:100::1/64
           end
       next
   end

   Inbandwidth must be configured for traffic shaping to take effect.

6. Configure firewall policies to allow IPv4 and IPv6 traffic to go through. Since traffic shaping is for inbound traffic on port2, the policy is defined from port2 to wan1:

   config firewall policy
       edit 20
           set uuid d9f9be4c-eaab-51ed-41d6-783cecc11c0c
           set srcintf "port2"
           set dstintf "wan1"
           set srcaddr "all"
           set dstaddr "all"
           set action accept
           set schedule "always"
           set service "ALL"
           set logtraffic all
       next
   end

   config firewall policy
       edit 21
           set uuid c535a92a-eaac-51ed-6e6c-3943f8c2dc8f
           set srcintf "port2"
           set dstintf "wan1"
           set srcaddr6 "all"
           set dstaddr6 "all"
           set action accept
           set schedule "always"
           set service "ALL"
           set logtraffic all
       next
   end
