NA521 - Switch Command - Show Arp v. Show mac-adddress-table - Otis - 03-14-2012
Could someone please confirm this: Which command will show the MAC addresses of stations connected to "switch" ports?
How2Pass Answer: show arp
Is How2Pass incorrect? Thank you.
When I go to Cisco site, I find ARP is mapping IP addresses to MAC addresses in Layer 3 devices. The show mac-address-table command maps MAC addresses to ports on the switch.

Cisco 3560 L3 Switch, I would say know both.
Switch#show arp

Thank you for your reply. So in essence, either answer is correct - show arp for L3 switch and show mac-address-table for L2 switch. I hope the CCNA differentiates which.
