Operating Modes

The Access Point can operate in a couple of configurations.
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
Access Point WLANs. Each WLAN can be configured to be broadcast by one or both Access Point
radios. An Altitude 4710 or Altitude 4750 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—The Access Point can assign private IP addresses.
●
Firewall—A Firewall protects against a number of known attacks.
●

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 Access Point's download site contains the following MIB files supporting the Access Point:
- EXTR-CC-AP4700-MIB-2.0 (standard MIB file)
- EXTR-AP4700-MIB-02a02
Make configuration changes to Access Point's individually. Optionally, use the Access Point
import/export configuration function to download settings to other Access Points.

MAC Address Assignment

MAC address assignments are as follows:
LAN (GE1)—The Access Point MAC address can be found underneath the Access Point chassis.
●
WAN (GE2)—The number of the LAN MAC address + 1.
●
LAN2—A virtual LAN not mapped to the LAN Ethernet port. This address is the lowest of the two
●
radio MAC addresses.
