Check Connection Two Interfaces

This scenario shows how to configure two Ethernet interfaces with an IP address and check ICMP and ARP connectivity.

Test ARP Connectivity

Description

Two Ethernet interfaces are configured in each node and the ‘ARPing’ command is used to check link connectivity (ARP protocol).

Scenario

Step 1: Set the following configuration in DUT0:

set interfaces ethernet eth0 address 192.168.100.10/24
set interfaces ethernet eth1 address 192.168.200.10/24
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 192.168.100.20/24
set interfaces ethernet eth1 address 192.168.200.20/24
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 3: Send arp ping from DUT0 to IP address 192.168.100.20:

admin@DUT0$ arping 192.168.100.20 interface eth0 timeout 5 count 1

Show output

ARPING 192.168.100.20 from 192.168.100.10 eth0
Unicast reply from 192.168.100.20 [DE:AD:BE:EF:6C:20]  0.985ms
Sent 1 probes (1 broadcast(s))
Received 1 response(s)

Step 4: Send arp ping from DUT1 to IP address 192.168.200.10:

admin@DUT1$ arping 192.168.200.10 interface eth1 timeout 5 count 1

Show output

ARPING 192.168.200.10 from 192.168.200.20 eth1
Unicast reply from 192.168.200.10 [DE:AD:BE:EF:6C:11]  0.732ms
Sent 1 probes (1 broadcast(s))
Received 1 response(s)

Test ICMP Connectivity

Description

Two Ethernet interfaces are configured in each node and the ‘Ping’ command is used to check network connectivity (ICMP protocol).

Scenario

Step 1: Set the following configuration in DUT0:

set interfaces ethernet eth0 address 192.168.100.10/24
set interfaces ethernet eth1 address 192.168.200.10/24
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 192.168.100.20/24
set interfaces ethernet eth1 address 192.168.200.20/24
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 3: Ping IP address 192.168.100.20 from DUT0:

admin@DUT0$ ping 192.168.100.20 local-address 192.168.100.10 count 1 size 56 timeout 1

Show output

PING 192.168.100.20 (192.168.100.20) from 192.168.100.10 : 56(84) bytes of data.

1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.327/0.327/0.327/0.000 ms

Step 4: Ping IP address 192.168.200.10 from DUT1:

admin@DUT1$ ping 192.168.200.10 local-address 192.168.200.20 count 1 size 56 timeout 1

Show output

PING 192.168.200.10 (192.168.200.10) from 192.168.200.20 : 56(84) bytes of data.
