Show ARP returns info only on VLAN 1

We have a number of 4507s. Most are managed via VLAN 1 address. All have multiple VLANS for traffic control. When I do a show ARP or show IP ARP the command only shows VLAN 1 info. No entries for any of the other VLANS on the switch. Any thoughts as to what I am doing wrong?

Re: Show ARP returns info only on VLAN 1

You will only see arp entries if the switch has a layer 3 interfaces for that vlan. Vlan1 has an ip that is why you see arp entires. For the other vlans you will only see layer2 , mac addresses

Are you trying to see the addresses that the switch has learned for its locally-generated traffic, or are you trying to look at the table of addresses learned by the switch for forwarding?

If the latter, try one of the following:

show mac-address-table

show mac address-table

Best regards,

Ed
