AP-5131 Introduction

1.1.8.9 Content Filtering
Content filtering allows system administrators to block specific commands and URL extensions from
going out through the AP-5131 WAN port only. Therefore, content filtering affords system
administrators selective control on the content proliferating the network and is a powerful screening
tool. Content filtering allows the blocking of up to 10 files or URL extensions and allows blocking of
specific outbound HTTP, SMTP, and FTP requests.
For instructions on configuring content filtering on the AP-5131, see Configuring Content Filtering
Settings on page 6-48.
1.1.9 VLAN Support
A Virtual Local Area Network (VLAN) is a means to electronically separate data on the same AP-5131
from a single broadcast domain into separate broadcast domains. By using a VLAN, you can group by
logical function instead of physical location. There are 16 VLANs supported on the AP-5131. An
administrator can map up to 16 WLANs to 16 VLANs and enable or disable dynamic VLAN
assignment. In addition to these 16 VLANs, the AP-5131 supports dynamic, user-based, VLANs when
using EAP authentication.
VLANs enable organizations to share network resources in various network segments within large
areas (airports, shopping malls, etc.). A VLAN is a group of clients with a common set of requirements
independent of their physical location. VLANs have the same attributes as physical LANs, but they
enable administrators to group clients even when they are not members of the same network
segment. For more information, see Configuring VLAN Support on page 5-5.
1.1.10 Multiple Management Accessibility Options
The AP-5131 can be accessed and configured using one of the following methods:
• Java-Based Web UI
• Human readable config file (imported via FTP or TFTP)
• MIB (Management Information Base)
• Command Line Interface (CLI) accessed via RS-232 or Telnet. Use the AP-5131 DB-9 serial
port for direct access to the command-line interface from a PC. Use Symbol's Null-Modem
cable (Part No. 25-632878-0) for the best fitting connection.
