„ You can assign a port to multiple interfaces (up to 255).

firewall traffic and Fast Ethernet ports for management traffic.
This example refers to the example illustrated in Figure 2 on page 31 .
„ The Switched Firewall management network is configured on port 1. The management
network is automatically configured when you ran the setup utility described in

„ Interface 2 is for untrusted (external) network traffic and resides on port 4.
1. (Optional) Reset the firewall to factory defaults.
If you are configuring the Switched Firewall for the first time, the unit is already set to factory
defaults. Therefore you may skip this step. However, if you wish to override the previous
configuration, then you should perform the following steps:
a. Enter
/boot/delete
to reset the Switched Firewall to the factory default.
b. Reboot the machine.
c. Perform the initial setup procedure (see Setting up the basic configuration on page 37 ).
2. Configure the ports and interfaces for the attached networks.

Nortel recommends that you assign a descriptive name to each port so that it is easier to
remember which port is assigned to a particular interface.
