##############
Server-Control
##############

These scenarios check DHCP server control options that affect server behavior.
This includes: authoritative, one-lease-per-client, lease time, and max-lease time.

*************************
Test One Lease Per Client
*************************

Description
===========

This scenario checks the ``one-lease-per-client`` option.
The test simulates a client that moves between networks by using different
dhcp-client-identifiers. Without one-lease-per-client, the server keeps
both leases active. With the option enabled, when the client requests a
new lease, the server automatically frees any other leases the client holds.
This is useful for mobile clients that change networks frequently.

*****************************
Test One Lease Per Client VRF
*****************************

Description
===========

This scenario checks the ``one-lease-per-client`` option when the server
is configured with VRF. Same behavior as the non-VRF test: when enabled,
the server frees old leases when a client requests a new one.

***************
Test Lease Time
***************

Description
===========

This scenario checks the ``lease`` and ``max-lease`` options.
The DHCP server configures custom lease times (default and maximum).
The client should receive a lease with the configured lease time.
The lease time determines how long the client can use the IP address before renewal.

**********************
Test Server-Identifier
**********************

Description
===========

This scenario checks the ``server-identifier`` option.
The DHCP server configures a specific server identifier IP address.
The client receives this identifier in the DHCP lease, which identifies the DHCP server.
This is useful in environments with multiple DHCP servers.
