Description

This article describes how to add a unique DHCP lease time to a Specific IP range under the same DHCP server.

Scope

7.2.4 onwards.

Solution

There might be a requirement where a specific set of IP ranges needs a higher DHCP lease and others need a lower DHCP lease time under the same DHCP server.

In the below example:

DHCP server has a global lease time of 7 days (604800 seconds).

1) First IP range will use the global DHCP lease time.
2) Second IP range will use 1 hour (3600 secs) as its DHCP lease time (only available over CLI).

# config system dhcp server
