How do I specify device to use

[GaikwadPratik]

@dresende
I have multiple interfaces defined on my server. One of them is used as prod interface and others might be used for internal communication. So how do I specify what device to be used in the library?

For instance, on terminal I use

# arping 192.168.122.3 -I prod
ARPING 192.168.122.3 from 192.168.122.2 prod
Unicast reply from 192.168.122.3 [52:54:00:6C:AE:66]  0.873ms
Unicast reply from 192.168.122.3 [52:54:00:6C:AE:66]  1.807ms
Unicast reply from 192.168.122.3 [52:54:00:6C:AE:66]  1.920ms
Unicast reply from 192.168.122.3 [52:54:00:6C:AE:66]  0.920ms

where in prod is the name of the interface

let me know if anything needs clarification

edit: After reading the code, I figured out that I need to use library like

arp.ping("192.168.122.3", {spa: "192.168.122.2"}, (err, info) => console.log(err, info))

OR

arp.ping("192.168.122.3", {sha: "52:54:00:93:e4:27"}, (err, info) => console.log(err, info))

but I always get error:
