ARP Table don´t show every host

[Luiz Eduardo]

On my OS6450 i have a lot of devices connected, the arp table only show who i ping with switch. Can someone help me?

If your switch isn't the default gateway for the clients, than the switch is working like a pure L2-switch. So this behavior is normal. The switch didn't need the ip addresses (L3). You have to look in the arp at your router/gateway (L3-switch or firewall). There you can find out the mac-addresses of the searched ip. With this mac you can look in the mac-address-table of the L2-switch.....
