Cisco Cisco Web Security Appliance S690 User Guide

The IP address, network mask, and host name to use to manage the Web Security appliance and, by 
default, for proxy (data) traffic. 

You can use the host name specified here when connecting to the appliance management interface (or in 
browser proxy settings if M1 is used for proxy data), but you must register it in your organization’s DNS.

Ethernet Port

(Optional) Check Use M1 port for management only if you want to use a separate 
port for data traffic. 

If you configure the M1 interface for management traffic only, you must configure 
the P1 interface for data traffic. You must also define different routes for 
management and data traffic. However, you can configure the P1 interface even 
when the M1 interface is used for both management and data traffic.

You can enable and configure the P1 port only in the System Setup Wizard. If 
you want to enable the P2 interface, you must do this after finishing the System 
Setup Wizard.

IP Address / 
Netmask

The IP address and network mask to use when managing the Web Security appliance 
on this network interface.

Hostname

The host name to use when managing the Web Security appliance on this 
network interface.

Layer-4 Traffic 
Monitor

The type of wired connections plugged into the “T” interfaces:

Duplex TAP. The T1 port receives both incoming and outgoing traffic. 

Simplex TAP. The T1 port receives outgoing traffic (from the clients to the 
Internet) and the T2 port receives incoming traffic (from the Internet to the 
clients).

Cisco recommends using Simplex when possible because it can increase 
performance and security.
