AP-5131 Access Point Product Reference Guide

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 detailed information on configuring VLAN support, see Configuring VLAN Support on page 5-4.
1.2.10 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.
1.2.11 Updatable Firmware
Symbol periodically releases updated versions of the AP-5131 device firmware to the Symbol Web
site. If the AP-5131 firmware version displayed on the System Settings page (see Configuring System
Settings on page 4-2) is older than the version on the Web site, Symbol recommends updating the
AP-5131 to the latest firmware version for full feature functionality.
For detailed information on updating the AP-5131 firmware using FTP or TFTP, see Updating Device
Firmware on page 4-41.
1.2.12 Programmable SNMP v1/v2/v3 Trap Support
Simple Network Management Protocol (SNMP) facilitates the exchange of management information
between network devices. SNMP uses Management Information Bases (MIBs) to manage the device
configuration and monitor Internet devices in remote locations. MIB information accessed via SNMP
is defined by a set of managed objects called object identifiers (OIDs). An object identifier (OID) is
used to uniquely identify each object variable of a MIB.
