Altitude 4700 Series Access Point Product Reference Guide

g Optionally, use the Enable PPP over Ethernet checkbox to enable Point-to-Point Protocol 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.

h 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.

i Specify the Username entered when connecting to the ISP. When the Internet session begins, the

ISP authenticates the username.

j 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 135.

6 Select the LAN#1 tab to set a minimum set of parameters to use the LAN#1 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 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 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.

d The Subnet Mask defines the size of the subnet. The first two sets of numbers specify the network

domain, the next set specifies the subset of hosts within a larger network. These values help

divide a network into subnetworks and simplify routing and data transmission.

e If using the static or DHCP Server option, enter a Default Gateway to define the numerical IP

address of a router the access point uses on the Ethernet as its default gateway.

f If using the static or DHCP Server option, enter the Primary DNS Server numerical IP address.

g If using the DHCP Server option, use the Address Assignment Range parameter to specify a range

of IP address reserved for mapping clients to IP addresses. If a manually (static) mapped IP

address is within the IP address range specified, that IP address could still be assigned to another
