The AP has many configuration parameters. This section discusses all the AP parameters and how to set them.
The AP has configuration options to operate the unit, including security access and interface control. Some parameters do not require modification. To configure the system parameters, follow the procedure below.
The AP automatically configures most radio parameters. Exercise extreme caution when adjusting radio parameters for the AP since these parameters affect system operations. Options in the RF Configuration window fine-tune the radio and WLAP functions. To configure the radio parameters, follow the procedure below.
To use a Point-to-Point (PPP) connection, choose the appropriate hardware connection (direct or modem). Verify the enable status of the serial port) in the System Configuration menu.
PPP direct is a direct null-modem serial cable connection between an AP and computer. To configure PPP direct, follow the procedure, below.
The PPP interface provides a connection using modems over a telephone line. Connect modems to the APs with null-modem (straight-through) serial cables. Designate one AP as the Originating AP and the other AP as the Answering AP. Configure the Originating AP with dial-out information to the answering AP. The answering AP waits for the originating AP to dial in to it.
The AP supports modems that use the generic Hayes Smartmodem command set. The AP uses Hayes commands and is capable of working with various modems of 19200 baud or faster. 3Com does not support modems the company has not qualified.
The following modems qualify to work with the AP:
Dial out manually through the Special Functions menu or dial out automatically when the system boots up.
To configure an originating AP, do the following from the UI of the originating AP:
To manually initiate dial-out from the originating AP to the answering AP, do the following:
An SNMP manager application gains access to the AP SNMP agent if it has the AP IP address. The agent configures as read-only, read-write or disabled to provide security when using SNMP. The AP sends specific traps for some conditions. Ensure the SNMP trap manager recognizes how to manage these traps.
The AP supports SNMP V1, MIB-II and the 3Com.MIB. To configure the SNMP agent, use the following procedure.
The ACL supports adding wireless client entries by individual MAC address or by a range of MAC addresses. To select a a method of adding wireless clients, do the following:
To select a range of MAC addresses, follow the procedure below.
When you enable the Access Control option, all wireless clients within the specified range can associate with the AP. Specify additional ranges as needed or add to the ACL using individual address entries.
The Access Control List screen provides a facility to add wireless clients to the ACL. To do so, follow the procedure below.
To toggle between enable or disable, locate the ACL in the System Configuration window, then do the following:
You can remove all wireless clients from the ACL by following the procedure below.
The Load ACL from wireless client List option, from the Special Functions menu, takes all currently associated wireless clients and creates an ACL from them. This builds an ACL without you having to manually type addresses. Edit the ACL using the add and delete functions.
The AP has two types of filtering: address filtering and type filtering. This section explains the two types of filtering and how to use them.
The AP can keep a list of the MAC addresses of wireless clients that are disallowed from associating with it. The Disallowed Addresses option provides security by preventing unauthorized access by known devices. Use the option for preferred association of wireless clients to APs. To filter by MAC address, follow the procedure below.
Packet types supported for the type filtering function include the 16-bit DIX Ethernet types. The list can include up to 16 types.
Set the type filters to forward or discard the types listed. To control the type filtering mode:
