I think openvswitch should be similar to a three-layer switch implemented at the software level? The Layer 3 switch supports displaying the arp cache table, such as using the command dis arp vlan <ID>, then how does openvswitch achieve the same effect? I tried the command ovs-dpctl dump-flows, which can print out the flow of arp request, as well as the correspondence between ip and mac address, but the function of displaying arp table was not found.
