3. Refer to the IP Filtering field to optionally enable the IP filtering feature, and (if enabled) apply
existing IP filters (and their rules and permissions) to LAN1 or LAN2.
NOTE
For an overview of IP Filtering and how to create a filter, see “Configuring IP filtering” on
page 156. For information on applying an existing filter to the IP packet flow of a WLAN, see
“Applying a filter to LAN1, LAN2 or a WLAN (1-16)” on page 158.
4. 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.
5. 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.
6. 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
MU 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 Brocade Mobility
7131N-FGR Access Point:
1. Select Network Configuration -> LAN -> LAN1 (or LAN2) from the Brocade Mobility 7131N-FGR
Access Point menu tree.
2. Click the Advanced DHCP Server button from within the LAN1 or LAN2 screen.
Enable IP Filtering Selecting this checkbox allows the LAN to employ filter policies and
rules to determine which IP packets are processed normally over
the LAN and which are discarded. If discarded, a packet is deleted
and ignored (as if never received).
IP Filtering Select the IP Filtering button to display a screen where existing IP
filter policies can be applied to the LAN to allow or deny IP packets
in either an incoming or outgoing direction based on the rules
defined for the policy.
