You can configure the appliance network interfaces by modifying IP address, subnet, and host 
name information for the Management, Data, and L4 Traffic Monitor interfaces. Table 21-1 
describes the network interface settings you can configure. 

Note — If the Management and Data interfaces are all configured, each must be assigned IP 
addresses on different subnets.

You can manage the network interfaces using the following methods:

• Web interface. Use the Network > Interfaces page. For more information, see 

• Command line interface. Use the 

ifconfig

 CLI command to create, edit, and delete 

network interfaces.

You can configure the Web Security appliance to use any of the following combinations of 
network interfaces for data traffic:

• M1 only

• M1 and P1

• M1, P1, and P2

Table 21-1 Web Security Appliance Network Interface Settings

Port Number

Description

Management

M1

By default, the Management interface is used to administer the 
appliance and Web Proxy (data) monitoring. However, you can 
configure the M1 port for management use only.

Data

P1 and P2 
(proxy)

The Data interfaces are used for Web Proxy monitoring and L4 
Traffic Monitor blocking (optional). You can also configure these 
interfaces to support outbound services such as DNS, software 
upgrades, NTP, and traceroute data traffic.
For more information about configuring the Data interfaces, see 
“Configuring the Data Interfaces” on page 465.

L4 Traffic 
Monitor

T1 and T2

The L4 Traffic Monitor interfaces are used to configure a duplex 
or simplex wiring type. 
• Duplex. The T1 interface receives incoming and outgoing 

traffic. 

• Simplex. T1 receives outgoing traffic and T2 receives incoming 

traffic.
