# TODO: Add operational data and VAT dump verification if/when avaliable
| TC01: Honeycomb can configure ipv4 proxyARP
| | [Documentation] | Check if Honeycomb can configure the proxyARP feature.
| | [Teardown] | Honeycomb removes proxyARP configuration | ${node}
| | Honeycomb configures proxyARP | ${node} | ${proxyarp_settings_ipv4}

| TC02: Honeycomb can enable proxyarp on an interface

| | ... | on an interface.
| | [Teardown] | Honeycomb disables proxyARP on interface
| | ... | ${node} | ${interface}
| | Honeycomb enables proxyARP on interface | ${node} | ${interface}

| TC03: DUT sends ARP reply on behalf of another machine from the IP range
| | [Documentation]
| | ... | [Top] TG-DUT1.
| | ... | [Ref] RFC1027.
| | ... | [Cfg] On DUT1 configure interface IPv4 address and proxy ARP
| | ... | for IP range, using Honeycomb API.
| | ... | [Ver] Make TG send ARP request to DUT1 interface,
| | ... | verify if DUT1 sends correct ARP reply on behalf of machine whose
| | ... | IP is in the configured range.
| | [Teardown] | Run Keywords
