LLDP Tests

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.

Test LLDP Voice

Description

This scenario checks LLDP voice without VLAN works when 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 voice dscp 54
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: Organization specific TLV (127), length 8: OUI ANSI/TIA (0x0012bb), Network policy Subtype (2), Application type [voice] (0x01), Flags [none] and DSCP value 54.

Test LLDP Voice Vlan

Description

This scenario checks LLDP voice with VLAN works when 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 voice dscp 54
set interfaces ethernet eth0 lldp voice vlan 100 cos 3
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: Organization specific TLV (127), length 8: OUI ANSI/TIA (0x0012bb), Network policy Subtype (2), Application type [voice] (0x01), Flags [Tagged] and Vlan id 100, L2 priority 3, DSCP value 54.

Test LLDP Packets Bridge

Description

This scenario checks that a device can send and receive LLDP packets when LLDP is configured on an Ethernet interface that is part of a bridge group.

Scenario

Step 1: Set the following configuration in DUT0 :

set interfaces bridge br0 address 192.168.100.101/24
set interfaces ethernet eth0 bridge-group bridge br0
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.
