Altitude 3500 Series Access Point Product Reference Guide
61
d Specify a Subnet Mask for the access point’s WAN connection. This number is available from the
ISP for a DSL or cable-modem connection, or from an administrator if the access point connects
to a larger network. A subnet mask uses a series of four numbers expressed in dot notation. For
example, 255.255.255.0 is a valid subnet mask.
e Define a Default Gateway address for the access point’s WAN connection. The ISP or a network
administrator provides this address.
f Specify the address of a Primary DNS Server. The ISP or a network administrator provides this
address.
6 Optionally, use the Enable PPP over Ethernet checkbox to enable Point-to-Point over Ethernet (PPPoE)
for a high-speed connection that supports this protocol. Most DSL providers are currently using or
deploying this protocol. PPPoE is a data-link protocol for dialup connections. PPPoE will allow the
access point to use a broadband modem (DSL, cable modem, etc.) for access to high-speed data
networks.
a Select the Keep Alive checkbox to enable occasional communications over the WAN port even
when client communications to the WAN are idle. Some ISPs terminate inactive connections,
while others do not. In either case, enabling Keep-Alive maintains the WAN connection, even
when there is no traffic. If the ISP drops the connection after the idle time, the access point
automatically reestablishes the connection to the ISP.
b Specify the Username entered when connecting to the ISP. When the Internet session begins, the
ISP authenticates the username.
c Specify the Password entered when connecting to the ISP. When the Internet session starts, the ISP
authenticates the password.
For additional access point WAN port configuration options, see “Configuring WAN Settings” on
page 125.
7 Click the LAN tab to set a minimum set of parameters to use the access point LAN interface.
a Select the Enable LAN Interface checkbox to forward data traffic over the access point’s LAN
connection. The LAN connection is enabled by default.
b Use the This Interface drop-down menu to specify how network address information is defined
over the access point’s LAN connection. Select DHCP Client if the larger corporate network uses
DHCP. DHCP is a protocol that includes mechanisms for IP address allocation and delivery of
host-specific configuration parameters from a DHCP server to a host. Some of these parameters
are IP address, network mask, and gateway. Select DHCP Server to use the access point as a
DHCP server over the LAN connection. Select the Bootp client option to enable a diskless system
to discover its own IP address.
NOTE
Extreme Networks recommends that the WAN and LAN ports should not both be configured as DHCP
clients.
c If using the static or DHCP Server option, enter the network-assigned IP Address of the access
point.
NOTE
DNS names are not supported as a valid IP address for the access point. The user is required to enter
a numerical IP address.
