3. Use the Port Settings field to define how the access point manages throughput over the WAN
port.
Primary DNS Server Specify the address of a primary Domain Name System (DNS) server. The
ISP or a network administrator provides this address.
A DNS server translates a domain name (for example, www.brocade.com)
into an IP address that networks can use.
Secondary DNS Server Specify the address of a secondary DNS server if one is used. A
secondary address is recommended if the primary DNS server goes
down.
More IP Addresses Click the More IP Addresses button to specify additional static IP
addresses for the Mobility 5181 Access Point. Additional IP addresses
are required when users within the WAN need dedicated IP addresses, or
when servers need to be accessed (addressed) by the outside world. The
More IP Addresses screen allows the administrator to enter up to seven
additional WAN IP addresses for the Mobility 5181 Access Point WAN.
Only numeric, non-DNS names can be used.
If PPP over Ethernet is enabled from within the WAN screen, the VPN
WAN IP Configuration portion of the More IP Addresses screen is
enabled. Enter the IP address and subnet mask used to provide the
PPPoE connection over the access point’s WAN port. Ensure the IP
address is a numerical (non DNS) name.
Refresh Click the Refresh button to update the network address information
displayed within the WAN IP Configuration field.
Enable Use the 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 allows a host
PC to use a broadband modem (DSL) for access to high-speed data
networks.
Username Specify a username entered when connecting to the ISP. When the Internet
session begins, the ISP authenticates the username.
Password Specify a password entered when connecting to the ISP. When the Internet
session starts, the ISP authenticates the password.
PPPoE State Displays the current connection state of the PPPoE client. When a PPPoE
connection is established, the status displays Connected. When no PPPoE
connection is active, the status displays Disconnected.
Keep-Alive Select the Keep-Alive check box to maintain the WAN connection
indefinitely (no timeout interval). Some ISPs terminate inactive
connections. Enabling Keep-Alive keeps the Mobility 5181 Access Point’s
WAN connection active, even when there is no traffic. If the ISP drops the
connection after an idle period, the Mobility 5181 Access Point
automatically re-establishes the connection to the ISP. Enabling Keep-Alive
mode disables (grays out) the Idle Time field.
