System Configuration TCP / IP Settings Configuring the SMC2555W-AG with an IP address expands your ability to manage the access point. A number of access point features depend on IP addressing to operate. Note: You can use the web browser interface to access IP addressing only if the access point already has an IP address that is reachable through your network.
Page 65 DHCP Client (Enable) – Select this option to obtain the IP settings for the access point from a DHCP (Dynamic Host Configuration Protocol) server. The IP address, subnet mask, default gateway, and Domain Name Server (DNS) address are dynamically assigned to the access point by the network DHCP server.
Page 66 System Configuration If you have management stations, DNS, RADIUS, or other network servers located on another subnet, type the IP address of the default gateway router in the text field provided. Otherwise, leave the address as all zeros (0.0.0.0). • Primary and Secondary DNS Address: The IP address of Domain Name Servers on the network.
Page 67 CLI Commands for TCP/IP Settings – From the global configuration mode, enter the interface configuration mode with the interface ethernet command. Use the ip dhcp command to enable the DHCP client, or no ip dhcp to disable it. To manually configure an address, specify the new IP address, subnet mask, and default gateway using the ip address command.
Page 68: Radius
A primary RADIUS server must be specified for the SMC2555W-AG to implement IEEE 802.1x network access control and Wi-Fi Protected Access (WPA) wireless security. A secondary RADIUS server may also be specified as a backup should the primary server fail or become inaccessible.
Page 69 Primary Radius Server Setup – Configure the following settings to use RADIUS authentication on the access point. • IP Address: Specifies the IP address of the RADIUS server. • Port: The UDP port number used by the RADIUS server for authentication messages.
Page 70 System Configuration authentication fails. (Range: 1-30; Default: 3) Note: For the Timeout and Retransmit attempts fields, accept the default values unless you experience problems connecting to the RADIUS server over the network. Secondary Radius Server Setup – Configure a secondary RADIUS server to provide a backup in case the primary server fails.
Page 71 CLI Commands for RADIUS – From the global configuration mode, use the radius-server address command to specify the address of the primary or secondary RADIUS servers. (The following example configures the settings for the primary RADIUS server.) Configure the other parameters for the RADIUS server. Then use the show show radius command from the Exec mode to display the current settings for the primary and secondary RADIUS servers.
Page 72: Authentication
This provides a basic level of authentication for wireless clients attempting to gain access to the network. A database of authorized MAC addresses can be stored locally on the SMC2555W-AG or remotely on a central RADIUS server. (Default: Local MAC) •...
Page 73 point. The Local MAC Authentication section enables the local database to be set up. Radius MAC: The MAC address of the associating station is • sent to a configured RADIUS server for authentication. When using a RADIUS authentication server for MAC address authentication, the server must first be configured in the Radius window (page 5-10).
Page 74 System Configuration • MAC Authentication Table: Displays current entries in the local MAC database. 802.1x Setup – IEEE 802.1x is a standard framework for network access control that uses a central RADIUS server for user authentication. This control feature prevents unauthorized access to the network by requiring an 802.1x client application to submit user credentials for authentication.
Page 75 all associated wireless clients. If 802.1x authentication is not initiated by a client, the access point will initiate authentication. Only those clients successfully authenticated with 802.1x are allowed to access the network. When 802.1x is enabled, the broadcast and session key rotation intervals can also be configured.

VLAN – Enables or disables VLAN tagging support on the SMC2555W-AG. If enabled, the access point will tag traffic passing from wireless clients to the wired network with the VLAN ID associated with each client on the RADIUS server. Up to 64...
Page 80 System Configuration A VLAN ID (1-4095) is assigned to a client after successful authentication using IEEE 802.1x and a central RADIUS server. The user VLAN IDs must be configured on the RADIUS server for each user authorized to access the network. If a user does not have a configured VLAN ID, the access point assigns the user to its own configured native VLAN ID.
Page 81 When VLAN filtering is disabled, the access point ignores the VLAN tags on any received frames. Local Bridge Filter – Controls wireless-to-wireless communications between clients through the SMC2555W-AG. However, it does not affect communications between wireless clients and the wired network.
Page 82 System Configuration CLI Commands for VLAN Support – From the global configuration mode use the native-vlanid command to set the default VLAN ID for the Ethernet interface, then enable VLANs using the vlan enable command. When you change the access point’s VLAN support setting, you must reboot the access point to implement the change.
Page 83 CLI Commands for Bridge Filtering – Use the filter local-bridge command from the global configuration mode to prevent wireless-to-wireless communications through the access point. Use the filter ap-manage command to restrict management access from wireless clients. To configure Ethernet protocol filtering, use the filter ethernet-type enable command to enable filtering and the filter ethernet-type protocol command to define the protocols that you want to filter.

Page 115: Wi-Fi Protected Access (Wpa)
Wi-Fi Protected Access (WPA) WPA employs a combination of several technologies to provide an enhanced security solution for 802.11 wireless networks. The SMC2555W-AG supports the following WPA components and features: IEEE 802.1x and the Extensible Authentication Protocol (EAP): WPA employs 802.1x as its basic framework for user authentication and dynamic key management.
Page 116 System Configuration Note: To implement WPA on wireless clients requires a WPA-enabled network card driver and 802.1x client software that supports the EAP authentication type that you want to use. Windows XP provides native WPA support, other systems require additional software.
Page 117 multicast and broadcast traffic must be the same for all clients, therefore it restricts encryption to a WEP key. When access is opened to both WPA and WEP clients, no authentication is provided for the WEP clients through shared keys. To support authentication for WEP clients in this mixed mode configuration, you can use either MAC authentication or 802.1x authentication.
Page 118 System Configuration WPA Key Management – WPA can be configured to work in an enterprise environment using IEEE 802.1x and a RADIUS server for user authentication. For smaller networks, WPA can be enabled using a common pre-shared key for client authentication with the access point.
Page 119 WPA Pre-Shared Key Type – If the WPA pre-shared-key mode is used, all wireless clients must be configured with the same key to communicate with the access point. • Hexadecimal: Enter a key as a string of 64 hexadecimal numbers. Alphanumeric: Enter a key as an easy-to-remember form of •...

Page 206: Turbo
Command Line Interface • For most wireless adapters, the channel for wireless clients is automatically set to the same as that used by the access point to which it is linked. Example SMC-AP(if-wireless g)#channel 1 SMC-AP(if-wireless g)# turbo This command sets the access point to an enhanced mode (not regulated in IEEE 802.11a) that provides a higher data rate of up to 108 Mbps.
Page 207: Ssid
ssid This command configures the service set identifier (SSID). Syntax ssid string string - The name of a basic service set supported by the access point. (Range: 1 - 32 characters) Default Setting Command Mode Interface Configuration (Wireless) Command Usage Clients that want to connect to the wireless network via an access point must set their SSIDs to the same as that of the access point.
Page 208: Dtim-Period
Command Line Interface Command Mode Interface Configuration (Wireless) Command Usage The beacon signals allow wireless clients to maintain contact with the access point. They may also carry power-management information. Example SMC-AP(if-wireless g)#beacon-interval 150 SMC-AP(if-wireless g)# dtim-period This command configures the rate at which stations in sleep mode must wake up to receive broadcast/multicast transmissions.
Page 209: Fragmentation-Length
indicates that the access point will save all broadcast/ multicast frames for the Basic Service Set (BSS) and forward them after every second beacon. • Using smaller DTIM intervals delivers broadcast/multicast frames in a more timely manner, causing stations in Power Save mode to wake up more often and drain power faster.
Page 210: Rts-Threshold
Command Line Interface collisions due to high network utilization, try setting the fragment size to send smaller fragments. This will speed up the retransmission of smaller frames. However, it is more efficient to set the fragment size larger if very little or no interference is present because it requires overhead to send multiple frames.
Page 211: Authentication
RTS frame, the station sends a CTS frame to notify the sending station that it can start sending data. • Access points contending for the wireless medium may not be aware of each other. The RTS/CTS mechanism can solve this “Hidden Node” problem. Example SMC-AP(if-wireless g)#rts-threshold 256 SMC-AP(if-wireless g)#...

Use the no form to disable encryption. Syntax encryption <key-length>...
Page 213: Key
• Note that WEP protects data transmitted between wireless nodes, but does not protect any transmissions over your wired network or over the Internet. • Although WEP keys are not needed for WPA, you must enable WEP encryption in order to enable all types of encryption in the access point.
Page 214: Transmit-Key
Command Line Interface Command Usage • To enable Wired Equivalent Privacy (WEP), use the authentication command to select the “shared key” authentication type, use the encryption command to specify the key length, and use the key command to configure at least one key. •...
Page 215: Transmit-Power
Command Mode Interface Configuration (Wireless) Command Usage • If you use WEP key encryption, the access point uses the transmit key to encrypt multicast and broadcast data signals that it sends to client devices. Other keys can be used for decryption of data from clients.
Page 216: Max-Association
Command Line Interface Command Usage • The “min” keyword indicates minimum power. • The longer the transmission distance, the higher the transmission power required. But to support the maximum number of users in an area, you must keep the power as low as possible.
Page 217: Multicast-Cipher
multicast-cipher This command defines the cipher algorithm used for broadcasting and multicasting when using Wi-Fi Protected Access (WPA) security. Syntax multicast-cipher <AES | TKIP | WEP> • AES - Advanced Encryption Standard • TKIP - Temporal Key Integrity Protocol • WEP - Wired Equivalent Privacy Default Setting Command Mode Interface Configuration (Wireless)
Page 218: Wpa-Clients
Command Line Interface • TKIP defends against attacks on WEP in which the unencrypted initialization vector in encrypted packets is used to calculate the WEP key. TKIP changes the encryption key on each packet, and rotates not just the unicast keys, but the broadcast keys as well. TKIP is a replacement for WEP that removes the predictability that intruders relied on to determine the WEP key.
Page 219 Command Usage Wi-Fi Protected Access (WPA) provides improved data encryption, which was weak in WEP, and user authentication, which was largely missing in WEP. WPA uses the following security mechanisms. Enhanced Data Encryption through TKIP WPA uses Temporal Key Integrity Protocol (TKIP). TKIP provides data encryption enhancements including per-packet key hashing (i.e., changing the encryption key on each packet), a message integrity check, an extended initialization...
