DHCP Duplicate Client Differentiation Using Client Subinterface Overview
In some network environments, client IDs and MAC addresses might not be unique,
resulting in duplicate clients. For example, two network adapters might be manufactured
with the same hardware address, resulting in a duplicate MAC address among the DHCP
clients attached to the router. A duplicate DHCP client occurs when a client attempts to
get a lease, and that client has the same client ID or the same MAC address as an existing
DHCP client.
When an extended DHCP local server receives a request from a new client that has a
duplicate ID or MAC address, the DHCP server terminates the address lease for the existing
client and returns the address to its original address pool. The DHCP server then assigns
a new address and lease to the new client.
