• Access Point - As an Access Point, the access point functions as a layer 2 bridge. The wired
uplink can operate as a trunk and support multiple VLANs. Up to 16 WLANs can be defined
and mapped to WLANs. Each WLAN can be configured to be broadcast by one or both
radios (unlike the AP-4131 model access point). An AP-5131 or AP-5181 can operate in both
an Access Point mode and Wireless Gateway/Router mode simultaneously. The network
architecture and access point configuration define how the Access Point and Wireless
Gateway/Router mode are negotiated.
• Wireless Gateway/Router - If operating as a Wireless Gateway/Router, the access point
functions as a router between two layer 2 networks: the WAN uplink (the ethernet port) and
the Wireless side. The following options are available providing a solution for single-cell
deployment:
• PPPoE - The WAN interface can terminate a PPPoE connection, thus enabling the access
point to operate in conjunction with a DSL or Cable modem to provide WAN connectivity.
• NAT - (Network Address Translation) on the Wireless interface. Using NAT, the router is
able to manage a private IP scheme. NAT allows translation of private addresses to the
WAN IP address.
• DHCP - On the Wireless side, the can assign private IP addresses.
• Firewall - In between the WAN and Wireless interfaces, a Firewall protects against a
number of known attacks.
1.3.7 Management Access Options
Managing the access point includes viewing network statistics and setting configuration options.
Statistics track the network activity of associated MUs and data transfers on the AP interfaces.
The access point requires one of the following connection methods to perform a custom installation
and manage the network:
• Secure Java-Based WEB UI - (use Sun Microsystems’ JRE 1.5 or higher available from Sun’s
Web site and be sure to disable Microsoft’s Java Virtual Machine if installed)
• Command Line Interface (CLI) via Serial, Telnet and SSH
• Config file - Human-readable; Importable/Exportable via FTP and TFTP
• MIB (Management Information Base) accessing the access point SNMP function using a
MIB Browser. The AP-5131 or AP-5181 downloads site contains the following 2 MIB files:
• Symbol-CC-WS2000-MIB-2.0 (standard MIB file)
• Symbol-AP-5131-MIB (AP-5131/AP-5181 MIB file)
