arp requests coming from core multilayer switch

Hi all, I have my core multilayer switch producing hundreds of arp requests each minute, I can only see the router as the source address of the broadcasts, is there anyway i could pick up the original source address, i think it could be the print server trying to connect to printers that are no longer there, im currently deleting printers that are no longer used from it, has anyone had this before ?

Re: arp requests coming from core multilayer switch

You can use various " ip arp inspection " commands for blocking a ARP request from a particulr interface .
