Added a new switch and all VTP information has changed? %LINK-5-CHANGED: Interface FastEthernet0/1, changed state to administratively down Switch-1(config)#interface GigabitEthernet0/2 Switch-1(config-if)#switchport Comparing and manipulating the AD in order to prefer it over the correct routing protocol In this section of the guide, we will look at the basic steps you should take on every network to protect your switches. All of these steps equally apply to router security (apart from switch port security of course) so review this section again when you come to router security because I won’t repeat the ground already covered.

When the device lease period expires or the device leaves the network, the particular IP address is handed back to the DHCP server, and then it can be assigned to another client.
