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. Each WLAN can
be configured to be broadcast by one or both Altitude 35xx radios. An Altitude 3510 or Altitude 3550
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 and LAN side, 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 2 MIB files:
●
EXTR-CC-adp35xx-MIB-2.0 (standard/common MIB file)
●
EXTR-adp35xx-MIB (Altitude 35xx specific MIB file)
Make configuration changes to access points individually. Optionally, use the access point
import/export configuration function to download settings to other access points.
For detailed information, see “Importing/Exporting Configurations” on page 103 .
Altitude 35xx MAC Address Assignment
For both an Altitude 3510 and Altitude 3550 model access point, MAC address assignments are as
follows:
●
WAN—The access point MAC address can be found on the bottom side of the access point chassis.
●
LAN1—WAN MAC a 1.
