AirWorks AWK-3131A Web Console Configuration Channel (for AP mode only) Setting Description Factory Default Available channels vary The AWK-3131A plays the role of wireless AP.
AirWorks AWK-3131A Web Console Configuration Open For security reasons, you should NOT set security mode to Open System, since authentication and data encryption are NOT performed in Open System mode. WEP (only for legacy mode) NOTE Moxa includes WEP security mode only for legacy purposes. WEP is highly insecure and is considered fully deprecated by the Wi-Fi alliance. We do not recommend the use of WEP security under any circumstances. According to the IEEE802.
AirWorks AWK-3131A Web Console Configuration WEP key 1-4 Setting Description Factory Default ASCII type: A string that can be used as a WEP seed for the RC4 encryption None 64 bits: 5 chars engine. 128 bits: 13chars HEX type: 64 bits: 10 hex chars 128 bits: 26 hex chars WPA/WPA2-Personal WPA (Wi-Fi Protected Access) and WPA2 represent significant improvements over the WEP encryption method. WPA is a security standard based on 802.
AirWorks AWK-3131A NOTE Web Console Configuration The key renewal value dictates how often the wireless AP encryption keys should be changed. The security level is generally higher if you set the key renewal value to a shorter number, which forces the encryption keys to be changed more frequently. The default value is 3600 seconds (6 minutes). Longer time periods can be considered if the line is not very busy.
AirWorks AWK-3131A Web Console Configuration Key renewal Setting Description Factory Default 60 to 86400 seconds Specifies the time period of group key renewal 3600 (seconds) (1 minute to 1 year) WPA/WPA2-Enterprise (for Client/Slave mode) When used as a client, the AWK-3131A can support three EAP methods (or EAP protocols): EAP-TLS, EAP-TTLS, and EAP-PEAP, corresponding to WPA/WPA-Enterprise settings on the AP side.
AirWorks AWK-3131A Web Console Configuration EAP-TTLS It is usually much easier to re-use existing authentication systems, such as a Windows domain or Active Directory, LDAP directory, or Kerberos realm, rather than creating a parallel authentication system. As a result, TTLS (Tunneled TLS) and PEAP (Protected EAP) are used to support the use of so-called “legacy authentication methods.” TTLS and PEAP work in a similar way.
AirWorks AWK-3131A Web Console Configuration PEAP There are a few differences in the TTLS and PEAP inner authentication procedures. TTLS uses the encrypted channel to exchange attribute-value pairs (AVPs), while PEAP uses the encrypted channel to start a second EAP exchange inside of the tunnel. The AWK-3131A provides MS-CHAP-V2 merely as an EAP method for inner authentication.
AirWorks AWK-3131A Web Console Configuration Multicast Rate Setting Description Factory Default Available rates You can set a fixed multicast rate for the transmission of 6M broadcast and multicast packets on a per-radio basis.
AirWorks AWK-3131A Web Console Configuration Noise protection Setting Description Factory Default Enable/Disable Adjusts the interference coping capability of the wireless signal. Disable This option should be enabled for communication distance under 500 meters, and should be disabled for communication distances over 500 meters. NOTE Make sure the same Transmission distance parameters are set in both AP and Client.
AirWorks AWK-3131A A A Web C Console Con nfiguration WLAN Certific cation Settings S s (for EAP-TLS E S in Clie ent/Slave mode only) o When EAP-TLS is used, a WLAN Certific cate will be required at the t client end to supportt WPA/WPA2-nterprise.
AirWorks AWK-3131A Web Console Configuration Advanced Settings Several advanced functions are available to increase the functionality of your AWK-3131A and wireless network system. A VLAN is a collection of clients and hosts grouped together as if they were connected to the broadcast domains in a layer 2 network. The DHCP server helps you deploy wireless clients efficiently. Packet filters provide security mechanisms, such as firewalls, in different network layers.
AirWorks AWK-3131A Web Console Configuration Finally, the switch would be configured to route packets from the marketing department to the appropriate corporate resources such as printers and servers. Packets from the human resource department could be restricted to a gateway that allowed access to only the Internet. A member of the human resource department could send and receive e-mail and access the Internet, but would be prevented from accessing servers or hosts on the local corporate network.
AirWorks AWK-3131A NOTE Web Console Configuration The VLAN feature can allow wireless clients to manage the AP. If the VLAN Management ID matches a VLAN ID, then those wireless clients who are members of that VLAN will have AP management access. CAUTION: Once a VLAN Management ID is configured and is equivalent to one of the VLAN IDs on the AP, all members of that User VLAN will have management access to the AP. Be careful to restrict VLAN membership to those with legitimate access to the AP.
AirWorks AWK-3131A Web Console Configuration Subnet mask Setting Description Factory Default subnet mask Identifies the type of sub-network (e.g., 255.255.0.0 for a None Class B network, or 255.255.255.0 for a Class C network) Primary/ Secondary DNS server Setting Description IP address of Primary/ The IP address of the DNS Server used by your network. After None Factory Default Secondary DNS server entering the DNS Server’s IP address, you can use URL as well.
AirWorks AWK-3131A Web Console Configuration ATTENTION Be careful when you enable the filter function: Drop + “no entity on list is activated” = all packets are allowed Accept + “no entity on list is activated” = all packets are denied IP Protocol Filter The AWK-3131A’s IP protocol filter is a policy-based filter that can allow or filter out IP-based packets with specified IP protocol and source/destination IP addresses.
AirWorks AWK-3131A Web Console Configuration TCP/UDP Port Filter The AWK-3131A’s TCP/UDP port filter is a policy-based filter that can allow or filter out TCP/UDP-based packets with a specified source or destination port. The AWK-3131A provides 8 entities for setting the range of source/destination ports of a specific protocol. In addition to selecting TCP or UDP protocol, you can set either the source port, destination port, or both. The end port can be left empty if only a single port is specified.
AirWorks AWK-3131A Web Console Configuration RSTP Settings (for Master or Slave mode only) AWK-3131A supports IEEE802.1D Spanning Tree Protocol and IEEE802.1w Rapid STP standards. In addition to eliminating unexpected path looping, STP/RSTP can provide a backup path recovery if a wired/ wireless path fails accidentally. The reliability and availability can increase because this fail-over function. AWK-3131A’s STP/RSTP feature is disabled by default.

AirWorks AWK-3131A Web Console Configuration SNMP Agent The AWK-3131A supports SNMP V1/V2c/V3. SNMP V1 and SNMP V2c use a community string match for authentication, which means that SNMP servers access all objects with read-only or read/write permissions using the community string public/private (default value). SNMP V3, which requires you to select an authentication level of MD5 or SHA, is the most secure protocol. You can also enable data encryption to enhance data security.
AirWorks AWK-3131A Web Console Configuration Remote Management Setting Description Factory Default Enable Allow remote management via SNMP agent Disable Disable Disallow remote management via SNMP agent Read community (for V1, V2c) Setting Description Factory Default V1, V2c Read Use a community string match with a maximum of 31 public Community characters for authentication. This means that the SNMP agent can access all objects with read-only permissions using this community string.
AirWorks AWK-3131A Web Console Configuration Link Fault Pass-Through (for Client/Slave mode only) This function means if Ethernet port is link down, wireless connection will be forced to disconnect. Once Ethernet link is recovered, AWK will try to connect to AP. If wireless is disconnected, AWK restarts auto-negotiation on Ethernet port but always stays in the link failure state. Once the wireless connection is recovered, AWK will try to recover the Ethernet link.
