Nov 15, 2020 · It is only Layer 3 network devices (routers, Layer 3 switches, firewalls) and hosts that create ARP tables. Layer 2 switches do not create an ARP table. ARP table is a list of MAC address (Layer 2) to IP address (Layer 3) bindings. ARP requests are broadcast between all Layer 3 devices and sent on the shared local subnet.

Jul 27, 2005 · No, since not every OS uses TCP/IP. Address Resolution Protocol (ARP) is one of the SUITE of protocols commonly known together as TCP/IP. If you block ARP, you will break TCP/IP. When a device using TCP/IP and Ethernet wants to send to another device - it will issue an ARP to retrieve the destination HARDWARE or MAC address (if it's not cached).

Mar 22, 2023 · ARP table requires L3 interface configure. If this switch is only Layer 2, you are not seeing the ARP for users connected to it. But you dont need.
