Policy
The following scenarios show how to configure different
traffic policies
. Policies can be used to manage and
classify network packets. traffic selectors
can be
configured to filter packets based on certain fields.
Test Policy Actions
Description
In this scenario, an ingress traffic policy
is configured
in DUT0 (‘eth0’ interface). Different traffic actions are
configured to accept, drop or limit incoming traffic.
Scenario
Step 1: Set the following configuration in DUT0
:
set interfaces ethernet eth0 address 10.0.0.1/24 set interfaces ethernet eth0 traffic policy in POLICY set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0' set traffic policy POLICY rule 1 action accept
Step 2: Set the following configuration in DUT1
:
set interfaces ethernet eth0 address 10.0.0.2/24 set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
Step 3: Ping IP address 10.0.0.1
from DUT1
:
admin@DUT1$ ping 10.0.0.1 count 1 size 56 timeout 1Show output
PING 10.0.0.1 (10.0.0.1) 56(84) bytes of data. 64 bytes from 10.0.0.1: icmp_seq=1 ttl=64 time=0.561 ms --- 10.0.0.1 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.561/0.561/0.561/0.000 ms
Step 4: Modify the following configuration lines in DUT0
:
delete traffic policy POLICY rule 1 action accept set traffic policy POLICY rule 1 action drop
Step 5: Expect a failure in the following command:
Initiate a udp connection from DUT1
to DUT0
and try to send some messages between both endpoints
admin@DUT0$ monitor test connection server 8080 udp admin@DUT1$ monitor test connection client 10.0.0.1 8080 udp
Step 6: Modify the following configuration lines in DUT0
:
delete traffic policy POLICY rule 1 action drop set traffic policy POLICY rule 1 action rate-limit 10
Step 7: Initiate a bandwidth test from DUT1
to DUT0
admin@DUT0$ monitor test performance server port 5001 admin@DUT1$ monitor test performance client 10.0.0.1 duration 5 port 5001Expect this output in
DUT1

Note
Previous test should show a very low bandwidth rate.
