Check Connection

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

Test ARP Connectivity

Description

An Ethernet interface is 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

Step 2: Set the following configuration in DUT1:

set interfaces ethernet eth0 address 192.168.100.20/24

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]  0.887ms
Sent 1 probes (1 broadcast(s))
Received 1 response(s)

Test ICMP Connectivity

Description

An Ethernet interface is 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

Step 2: Set the following configuration in DUT1:

set interfaces ethernet eth0 address 192.168.100.20/24

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.
