Test LLDP Packets
Description
This scenario checks that a device can send and receive LLDP packets when LLDP is configured on an Ethernet interface.
Scenario
Step 1: Set the following configuration in DUT0 :
set interfaces ethernet eth0 address 192.168.100.101/24 set interfaces ethernet eth0 lldp set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
Step 2: Set the following configuration in DUT1 :
set interfaces ethernet eth0 address 192.168.100.102/24 set interfaces ethernet eth0 lldp set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
Note
Start packet capture in DUT0.
Step 3: Run command traffic dump monitor interface eth0 detail at DUT0.
Note
Stop packet capture in DUT0 and expect LLDP.
