Policy

Tests for HTB classification using traffic policies. Verifies that rate shaping works with policy-based classification and that assigning traffic to a non-leaf parent class causes it to fall to the default class.

Test HTB Policy Rate TCP 8080

Description

Configures a two-level HTB hierarchy with traffic policy pre-classification and verifies that TCP traffic on port 8080 is shaped to ~30 Mbps by class 2 (child of class 1).

Scenario

Step 1: Set the following configuration in DUT0 :

set interfaces ethernet eth0 address 10.0.0.2/24
set interfaces ethernet eth0 traffic control out QDISC
set interfaces ethernet eth0 traffic policy out CLASSIFIER
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
set traffic control QDISC type htb bandwidth 100
set traffic control QDISC type htb class 1 bandwidth percentage 50
set traffic control QDISC type htb class 1 ceiling percentage 100
set traffic control QDISC type htb class 2 bandwidth rate 30
set traffic control QDISC type htb class 2 parent 1
set traffic control QDISC type htb class 3 bandwidth percentage 10
set traffic control QDISC type htb default-class 3
set traffic policy CLASSIFIER rule 1 selector SEL_TCP_8080
set traffic policy CLASSIFIER rule 1 set class 2
set traffic selector SEL_TCP_8080 rule 1 destination port 8080
set traffic selector SEL_TCP_8080 rule 1 protocol tcp

Step 2: Set the following configuration in DUT1 :

set interfaces ethernet eth0 address 10.0.0.1/24
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 3: Ping the IP address 10.0.0.1 from DUT0:

admin@DUT0$ ping 10.0.0.1 count 1 size 56 timeout 1

Step 4: Initiate a bandwidth test from DUT0 to DUT1

admin@DUT1$ monitor test performance server port 8080
admin@DUT0$ monitor test performance client 10.0.0.1 duration 5 port 8080 parallel 1

Step 5: Run the command traffic control show on DUT0 and check whether the output matches the following regular expressions:

class 2\s+1:1\s+[1-9]
