# Monitoring DHCP Traffic Between Remote Clients and DHCP Servers

You can configure the router to monitor DHCP packets between remote clients and specified DHCP servers. You can specify up to four DHCP servers.

To monitor DHCP packets between remote clients and a DHCP server:

- Issue the ip dhcp-external server-address command and specify the IP address of the DHCP server:
  host1(config)#ip dhcp-external server-address 10.10.10.1 host1(config)#ip dhcp-external server-address 10.20.10.1

  You can specify a maximum of four DHCP servers to monitor.
