A server is showing twice or more on my L2 switch ARP table

Same IP address, mac address, and ethernet port.

What could be causing this?

Describe the switch? – Michael Hampton Feb 26 '14 at 23:48
It's a 3COM 5500G-EI 48-Port - Thanks – atomicluis Feb 27 '14 at 0:09
Are you viewing the table by MAC address or port? – joeqwerty Feb 27 '14 at 0:10
I am using the command "display arp" and it gives me the IP address, MAC address and switch port. Sometimes I will get duplicate entries. – atomicluis Feb 27 '14 at 0:20
