## Enable ICMP Echo

Before the server offers a particular IP address to a client, generate an ICMP request to ensure that the address to be offered is not in use by any host in the network. In this example, this is performed in switch 1.

1. Enable an ICMP echo request.

       SEFOS# configure terminal
       SEFOS(config)# ip dhcp ping packets
       SEFOS(config)# end

2. View the ICMP echo configuration for the DHCP server.

       SEFOS# show ip dhcp server information
