Does the ARP table exist on the access switch
The Switch maintains an ARP table which is comprised of mapped IP addresses and MAC addresses. If you have a switch that can be pinged / managed etc over the network then yes it does have an ARP table. 06-28-2006 02:43 PM PC's also have arp table and we know PCs are not. Only L3 devices contain ARP tables. It's my understanding that you would model a switch as a set of (switch) ports. Ports are numbered packet queues. An ARP (Address Resolution Protocol) table is a crucial component of a network switch, enabling it to forward data packets efficiently within a local. By extension, an ARP table is simply the method for storing the information discovered through ARP.

MAC table content of core switches
A MAC (Media Access Control) address table, also known as a forwarding database (FDB), serves as the switch's “memory” for device locations within a Local Area Network (LAN). It is represented in hexadecimal. The switch keeps. At the heart of a switch's functionality lies the MAC address table —a critical component that enables efficient data forwarding by intelligently mapping network paths. It explains forwarding decisions at Layer 2, exposes mispatches, reveals loops and misconfigured trunks, and even helps validate segmentation. By the end, you'll understand how switches use these.
