Test HTB Matches
Description
This scenario tests different matches in HTB qdisc.
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 local-out POL 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 100 set traffic control QDISC type htb class 2 bandwidth percentage 100 set traffic control QDISC type htb default-class 2 set traffic control QDISC type htb match 1 class 1 set traffic policy POL rule 1 set mark 99
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'
