Oct 25, 2018 · Maximum Client Lead Time (MCLT) is defined as the maximum amount of time that one server can extend a lease for a client's binding beyond the time known by the partner server.

1) DHCP lease times mean nothing if the computer is connected (RFC2131 is what's pertinent here). As long as a client is connected to the network, it can (and will/should) keep requesting (and being granted) the same address before the lease time expires, and the server will keep granting it.

Maximum client lead time (MCLT)) The maximum amount of time that one server can extend a lease for a DHCP client beyond the time known by the partner server. Maximum client lead time (MCLT) State switchover interval.

DHCP snooping is built on the concept of using one or more trusted ports that have been identified as having legitimate DHCP servers attached. As clients communicate on the network, the switch builds a "bindings table"—a database that lists the client MAC address, DHCP-assigned address, switchport, VLAN, and remaining DHCP lease time. May 07, 2019 · For best practice, I wouldn’t recommend using Static IPs inside of the DHCP pool range. For example, you’d want to have your DHCP range from .100 to .199 and then have your servers in .10 to .19 and printers from .20 to .30, etc… It just avoids problems… As for DHCP reservations, you can have those within or outside of your DHCP scope
