This example shows how to configure these DHCP servers. The VLANs are already

configured.

In this example, the Switch is a DHCP server for clients on VLAN 1 and VLAN 2. The DHCP

clients in VLAN 1 are assigned IP addresses in the range 192.168.1.100 to 192.168.1.200 and

clients on VLAN 2 are assigned IP addresses in the range 172.16.1.30 to 172.16.1.130.

This example shows how to configure the DHCP server for VLAN 1 with the configuration
