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
Protocol Address Age (min) Hardware Addr Type Interface
Internet 10.0.0.1 0 0006.2A7A.AE01 ARPA FastEthernet0/1
Internet 10.0.0.2 - 00E0.F7C8.C501 ARPA FastEthernet0/1
Internet 192.168.1.1 - 00D0.D33A.5609 ARPA Vlan1
Internet 192.168.26.1 - 00D0.D33A.5609 ARPA Vlan260
Internet 192.168.55.1 - 00D0.D33A.5609 ARPA Vlan55
Switch#show mac-address-table

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.
