| ■ What Effect Do DHCP Devices Have On The Map? |

How Traffix | Traffix™ Manager normally uses the Network Layer Address (for example, |
Manager Monitors | IP address, IPX address) as the unique way to identify objects on your |
DHCP Devices | network. However, the IP address of devices managed using the Dynamic |
| Host Control Protocol (DHCP) can change, and therefore this is an |
| unreliable method of identification for these devices. |
| The only certain way of identifying such devices in the Map is to use the |
| MAC address of the device. You can use the DHCP configuration file to |
| specify which devices you want Traffix Manager to identify using this |
| method. You can open this file by clicking DHCP Setup in the Traffix |
| Control Panel. |

What Effect Do | If a device which is managed using DHCP is discovered on your network, |
DHCP Devices Have | it may appear on the Traffix Manager Map as a normal device until Traffix |
On The Map? | Manager realizes it is a DHCP device. |
| A DHCP device requests an IP address from the DHCP server. DHCP is a |
| dynamic protocol, and the DHCP server can provide a different IP address |
| for the same device each time this request is made. If, according to your |
| local DHCP policy, the IP address of a device changes, the device will |
| appear exactly the same in the Map, except that its IP address will |
| change. |
| If the old IP address of a device is assigned to a new MAC address, a new |
| device is created in the Map. This new device will have the old IP address |
| and the new MAC address attribute assigned to it. The original device |
