my Cisco 4006 SUP II only show entries in ARP after I connect to the switch via telnet. It will only have entries in ARP for the computers that I have used to telnet into the SUP. The switch appears to be working fine as all the computers can talk to each other. Why would the table not show entries for all devices?
