3. Click Apply to save any changes to the LAN1 or LAN2 screen. Navigating away from the screen
without clicking the Apply button results in all changes to the screen being lost if the prompts
are ignored.
4. Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the
settings displayed on the LAN1 or LAN2 screen to the last saved configuration.
5. Click Logout to securely exit the Access Point applet. A prompt displays confirming the logout
before the applet is closed.
Configuring Advanced DHCP Server Settings
Use the Advanced DHCP Server screen to specify (reserve) static (or fixed) IP addresses for specific
devices. Every wireless, 802.11x-standard device has a unique Media Access Control (MAC)
address. This address is the device's hard-coded hardware number (shown on the bottom or back).
An example of a MAC address is 00:A0:F8:45:9B:07.
The DHCP server can grant an IP address for as long as it remains in active use. The lease time is
the number of seconds an IP address is reserved for re-connection after its last use. Using very
short leases, DHCP can dynamically reconfigure networks in which there are more computers than
available IP addresses. This is useful, for example, in education and customer environments where
Client users change frequently. Use longer leases if there are fewer users.
To generate a list of client MAC address to IP address mappings for the Mobility 5181 Access Point:
1. Select Network Configuration -> LAN -> LAN1 (or LAN2) from the Mobility 5181 Access Point
menu tree.
2. Click the Advanced DHCP Server button from within the LAN1 or LAN2 screen.
3. Specify a lease period in seconds for available IP addresses using the DHCP Lease Time
(Seconds) parameter. An IP address is reserved for re-connection for the length of time you
specify. The default interval is 86400 seconds.
4. Click the Add button to create a new table entry within the Reserved Clients field.
If a statically mapped IP address is within the IP address range in use by the DHCP server, that
IP address may still be assigned to another client. To avoid this, ensure all statically mapped IP
addresses are outside of the IP address range assigned to the DHCP server.
If multiple entries exist within the Reserved Clients field, use the scroll bar to the right of the
window to navigate.
WINS Server Enter the numerical (non DNS name) IP address of the WINS server. WINS
is a Microsoft NetBIOS name server. Using a WINS server eliminates the
broadcasts needed to resolve computer names to IP addresses by
providing a cache or database of translations.
Mesh STP Configuration Click the Mesh STP Configuration button to define bridge settings for this
specific LAN. Each of the access point’s two LANs can have a separate
mesh configuration. As the Spanning Tree Protocol (STP) mentions, each
mesh network maintains hello, forward delay and max age timers. These
settings can be used as is using the current default settings, or be
modified. However, if these settings are modified, they need to be
configured for the LAN connecting to the mesh network WLAN.
For information on mesh networking capabilities, see
“Configuring Mesh
Networking” on page 359. If new to mesh networking and in need of an
overview, see “Configuring Mesh Networking” on page 359.
