NOTE
DNS names are not supported as a valid IP address. The user is required to enter a numerical
IP address.
Once the IP address is entered, the Mobility 5181 Access Point’s Network Time Protocol (NTP)
functionality is engaged automatically. Refer to the Mobility 5181 Access Point Product
Reference Guide for information on defining alternate time servers and setting a
synchronization interval for the Mobility 5181 Access Point to adjust its displayed time. Refer to
“Configuring Network Time Protocol (NTP)” on page 76 (if necessary) for information on setting
alternate time servers and setting a synchronization interval for the Mobility 5181 Access Point
to adjust its displayed time.
5. Click the WAN tab to set a minimum set of parameters for using the WAN interface.
a. Select the Enable WAN Interface check box to enable a connection between the Mobility
5181 Access Point and a larger network or outside world through the WAN port. Disable
this option to effectively isolate the Mobility 5181 Access Point’s WAN connection. No
connections to a larger network or the Internet will be possible. Clients cannot
communicate beyond the configured subnets.
b. Select the This Interface is a DHCP Client check box to enable DHCP for the Mobility 5181
Access Point’s WAN connection. This is useful, if the larger corporate network or Internet
Service Provider (ISP) 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.
NOTE
Brocade recommends that the WAN and LAN ports should not both be configured as DHCP
clients.
c. Specify an IP address for the Mobility 5181 Access Point’s WAN connection. An IP address
uses a series of four numbers expressed in dot notation, for example, 190.188.12.1 (no
DNS names supported).
d. Specify a Subnet Mask for the Mobility 5181 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 Mobility 5181 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 Mobility 5181 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 check box 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.
