Hi,
I have scarce behavior in Switch Port.
network based Pinpad is connected to 2960 switch port and the port configuration is normal access VLAN allowed (sw mode acc & sw acc vla XXX) pinpad is configured with Static IP address.
There is no mac address table under the interface. if i ping the device, i could see the mac address. once i stop pinging, MAC disappears after few secs
if i unplug the cable and connect it back nothing is working. any suggestion ??

Hello,
what is the brand and type of that Pinpad ?
Try:
clear mac address-table dynamic interface FastEthernet0/x
Do you have the same issue when you connect a 'normal' device such as a laptop or PC to the switchport ?

if i set to dhcp it works good but i can see MAC only when i ping the pinpad and i tried clearing the mac.
i don't have any issue with other devices.
