Mark

The following scenario shows how to filter packets based on the meta mark attribute using traffic selectors.

Test Drop Outgoing ICMP Traffic

Description

This scenario demonstrates how to use the special filter mark to drop outgoing ICMP packets without a packet meta mark in DUT0.

Scenario

Step 1: Set the following configuration in DUT1:

set interfaces ethernet eth0 address 10.0.0.2/24

Step 2: Set the following configuration in DUT0:

set interfaces ethernet eth0 address 10.0.0.1/24
set interfaces ethernet eth0 traffic policy out DROP_UNMARKED
set traffic policy DROP_UNMARKED rule 1 action drop
set traffic policy DROP_UNMARKED rule 1 log prefix DROP
set traffic policy DROP_UNMARKED rule 1 selector SEL_UNMARKED
set traffic policy DROP_UNMARKED rule 2 action accept
set traffic policy DROP_UNMARKED rule 2 log prefix BYPASS
set traffic selector SEL_UNMARKED rule 1 mark 0
set traffic selector SEL_UNMARKED rule 1 protocol icmp

Step 3: Ping IP address 10.0.0.2 from DUT0:

admin@DUT0$ ping 10.0.0.2 mark 1 count 1 size 56 timeout 1
