  • Port no of that computer is to be used
  • Switch> enable
  • Switch# configure terminal
  • Switch(configure)# mac-add-table static 0052.45b5.2g52(mac address)  int fa 0/1(port no) vlan 1
  • If we want that to take the mac address automatically we use the work “sticky” for mac address as
  • Switch(configure)# mac-add-table static sticky int fa 0/1 vlan 1

If we want to remove it from table as

  • Switch(configure)# no mac-add-table static 0052.45b5.2g52 int fa 0/1 vlan 1 and save it as
