Useful DHCP Show Commands

In this post I will demonstrate a few useful show commands that will help me see the state of the routers DHCP server which I set up in the previous post.

• show ip dhcp binding
• show ip dhcp pool
• show ip dhcp server statistics

These commands were run after a computer was issued the IP 10.0.2.1 from the dmz pool.
