Chapter 1 Introduction Auranet series products provide wireless coverage solutions for small-medium business. They can either work independently as standalone APs or be centrally managed by the EAP Controller software, providing a flexible, richly-functional but easily-configured enterprise-grade wireless network for small and medium business. “Celling lamp” appearance and easily mounting design with chassis make EAP easy to be installed on a wall or ceiling and blend in with most interior decorations. EAP245: Figure 1-1 Top View of the EAP 2
Chapter 2 Network Topology A typical network topology for the EAP is shown below. Figure 2-1 Typical Topology To deploy an EAP in your local network, a DHCP server is required to assign IP addresses to the EAP and clients. Typically, a router acts as the DHCP server. A computer running the EAP Controller software can locate in the same or different subnet with the EAPs. EAPEAPEAPManangement HostSwitchRouterInternetClientsEAP Controller3
The EAP can be managed by the EAP Controller software, which is a management software specially designed for the TP-Link EAP devices on a local wireless network, allowing you to centrally configure and monitor mass EAP devices using a web browser on your PC. For more information about the EAP Controller, please find the EAP Controller User Guide from our official website: http://www.tp-link.com/en/support/download/ 4
Chapter 3 Management Mode Auranet series products can either work under the control of the EAP Controller software or work independently as a standalone access point. When user establishes a large-scale wireless network, the management of every single AP in the network is complex and complicated. With the EAP Controller software, you can centrally manage the mass APs simply in a web browser. The Standalone mode applies to a relatively small-sized wireless network. EAPs in the Standalone mode cannot be managed centrally by the EAP Controller software. 3.1 Standalone Mode By default, the EAP works independently as a standalone access point. By entering the IP address of the standalone EAP, you can log in to its web interface and perform configurations. The factory default IP address configuration of the EAP is DHCP (Dynamic Host Configuration Protocol). Before you access the web interface of the EAP, please make sure the DHCP server works properly. Typically, a router acts as the DHCP server. Follow the steps below to log in to the web interface of a standalone EAP. 1. Launch a web browser, enter the DHCP address in the address field and press the Enter key. 2. Enter admin (all lowercase) for both username and password. 3.2 Managed Mode The EAP will become a managed AP once it is adopted via the EAP Controller software. Users can manage the AP via a web browser. Refer to the EAP Controller User Guide from our website at www.tp-link.com to know more about EAP Controller software. 3.3 Switch to Standalone Mode The web interface of a specific EAP is not available once this EAP is adopted by the EAP Controller. You can Forget the EAP via the EAP Controller to turn it back as a standalone AP. Refer to the EAP Controller User Guide from our website at www.tp-link.com to learn more. TIPS: Proceed to the following chapters for information on using the EAP in standalone mode. 5
Chapter 4 Network On Network page you can configure the IP address of the standalone EAP. Figure 4-1 Network Page Dynamic/Static: By default, the EAP device obtains an IP address from a DHCP server (typically a router). Select Static to configure IP address manually. Fallback IP: If the EAP fails to get a dynamic IP address from a DHCP server within ten seconds, the fallback IP will work as the IP address of the device. After that, however, the device will keep trying to obtain an IP address from the DHCP server until it succeeds. DHCP Fallback IP/IP MASK: Enter the fallback IP/IP mask. DHCP Fallback Gateway: Enter the fallback gateway. 6
Chapter 5 Wireless Wireless page, consisting of Wireless Settings, Portal, MAC Filtering, Scheduler, QoS and Rogue AP Detection, is shown below. Figure 5-1 Wireless Page 7
5.1 Wireless Settings Following is the page of Wireless Settings. Figure 5-2 Wireless Settings Page 8
5.1.1 Wireless Basic Settings Figure 5-3 Wireless Basic Settings 2.4GHz Wireless Radio: Check the box to enable 2.4GHz Wireless Radio. Wireless Mode: Select the protocol standard for the wireless network. For 2.4GHz network, we recommend that select 802.11b/g/n, in which way clients supporting any one of these modes can access your wireless network. For 5GHz network, we recommend that select 802.11a/n or 802.11a/n/ac, in which way clients supporting any one of these modes can access your wireless network. Channel Width: Select the channel width of this device. According to IEEE 802.11n standard, using a higher bandwidth can increase wireless throughput. However, users may choose lower bandwidth due to the following reasons: 1. To increase the available number of channels within the limited total bandwidth. 2. To avoid interference from overlapping channels occupied by other devices in the environment. 3. Lower bandwidth can concentrate higher transmit power, increasing stability of wireless links over long distances. TIPS: Proceed to the following chapter for information on configuring the wireless network of the EAP. The configuring information of 2.4GHz is taken as the example. 9
Channel: Select the channel used by this device to improve wireless performance. 1/2412MHz means the Channel is 1 and the frequency is 2412MHz. By default, channel is automatically selected. Tx power: Enter the transmit power value. By default, the value is 20. If the maximum transmit power is set to be larger than local regulation allows, the maximum Tx power regulated will be applied in actual situation. NOTE: In most cases, it is unnecessary to select maximum transmit power. Selecting larger transmit power than needed may cause interference to neighborhood. Also it consumes more power and will reduce longevity of the device. Select a certain transmit power is enough to achieve the best performance. 5.1.2 SSIDs SSIDs can work together with switches supporting 802.1Q VLAN. The EAP can build up to eight virtual wireless networks per radio for users to access. At the same time, it adds different VLAN tags to the clients which connect to the corresponding wireless network. It supports maximum 8 VLANs per radio. The clients in different VLAN cannot directly communicate with each other. Clients connected to the device via cable do not belong to any VLAN. Thus wired client can communicate with all the wireless clients despite the VLAN settings. Click in the Modify column, the following content will be shown. Figure 5-4 SSIDs 10
Click to add up to 8 wireless networks per radio. SSID Name: Enter up to 32 characters as the SSID name. Wireless VLAN ID: Set a VLAN ID for the wireless network. Wireless networks with the same VLAN ID are grouped to a VLAN. SSID Broadcast: Enable this function, AP will broadcast its SSID to hosts in the surrounding environment, as thus hosts can find the wireless network identified by this SSID. If SSID Broadcast is not enabled, hosts must enter the AP’s SSID manually to connect to this AP. Security Mode: Select the security mode of the wireless network. For the security of wireless network, you are suggested to encrypt your wireless network. This device provides three security modes: WPA-Enterprise, WPA-PSK (WPA Pre-Shared Key) and WEP (Wired Equivalent Privacy). WPA-PSK is recommended. Settings vary in different security modes as the details are in the following introduction. Select None and the hosts can access the wireless network without password. Portal: Portal provides authentication service for the clients who want to access the wireless local area network. For more information, refer to 5.2 Portal. After Portal is enabled, the configurations in 5.2 Portal will be applied. SSID Isolation: After enabling SSID Isolation, the devices connected in the same SSID cannot communicate with each other. Modify: Click to open the page to edit the parameters of SSID. Click to delete the SSID. Following is the detailed introduction of security mode: WEP, WPA-Enterprise and WPA-PSK.  WEP WEP (Wired Equivalent Privacy), based on the IEEE 802.11 standard, is less safe than WPA-Enterprise or WPA-PSK. NOTE: WEP is not supported in 802.11n mode. If WEP is applied in 802.11n mode, the clients may not be able to access the wireless network. If WEP is applied in 11b/g/n mode (in the 2.4GHz frequency band) or 11a/n (in the 5GHz frequency band), the device may work at a low transmission rate. 11
Figure 5-5 Security Mode-WEP Type: Select the authentication type for WEP.  Auto: The default setting is Auto, which can select Open System or Shared Key automatically based on the wireless station's capability and request.  Open System: After you select Open System, clients can pass the authentication and associate with the wireless network without password. However, correct password is necessary for data transmission.  Shared Key: After you select Shared Key, clients has to input password to pass the authentication, or it cannot associate with the wireless network or transmit data. Key Selected: You can configure four keys in advance and select one as the present valid key. Wep Key Format: Select the wep key format ASCII or Hexadecimal.  ASCII: ASCII format stands for any combination of keyboard characters in the specified length.  Hexadecimal: Hexadecimal format stands for any combination of hexadecimal digits (0-9, a-f, A-F) in the specified length. Key Type: Select the WEP key length for encryption.  64-bit: You can enter 10 hexadecimal digits (any combination of 0-9, a-f, A-F without null key) or 5 ASCII characters.  128-bit: You can enter 26 hexadecimal digits (any combination of 0-9, a-f, A-F without null key) or 13 ASCII characters.  152-bit: You can enter 32 hexadecimal digits (any combination of 0-9, a-f, A-F without null key) or 16 ASCII characters. Key Value: Enter the key value. 12
 WPA-Enterprise Based on RADIUS server, WPA-Enterprise can generate different passwords for different users and it is much safer than WPA-PSK. However, it costs much to maintain and is more suitable for enterprise users. At present, WPA-Enterprise has two versions: WPA-PSK and WPA2-PSK. Figure 5-6 Security Mode_WPA-Enterprise Version: Select one of the following versions:  Auto: Select WPA-PSK or WPA2-PSK automatically based on the wireless station's capability and request.  WPA-PSK: Pre-shared key of WPA.  WPA2-PSK: Pre-shared key of WPA2. Encryption: Select the encryption type, including Auto, TKIP, and AES. The default setting is Auto, which can select TKIP (Temporal Key Integrity Protocol) or AES (Advanced Encryption Standard) automatically based on the wireless station's capability and request. AES is more secure than TKIP and TKIP is not supported in 802.11n mode. It is recommended to select AES as the encryption type. RADIUS Server IP/Port: Enter the IP address/port of the RADIUS server. RADIUS Password: Enter the shared secret of RADIUS server to access the RADIUS server. Group Key Update period: Specify the group key update period in seconds. The value can be either 0 or 30-8640000 seconds. NOTE: Encryption type TKIP is not supported in 802.11n mode. If TKIP is applied in 802.11n mode, the clients may not be able to access the wireless network of the EAP. If TKIP is applied in 13
11b/g/n mode (in the 2.4GHz frequency band) or 11a/n (in the 5GHz frequency band), the device may work at a low transmission rate.  WPA-PSK Based on pre-shared key, security mode WPA-PSK is characterized by high security and simple configuration, which suits for common households and small business. WPA-PSK has two versions: WPA-PSK and WPA2-PSK. Figure 5-7 Security Mode_WPA-PSK Version:  Auto: Select WPA or WPA2 automatically based on the wireless station's capability and request.  WPA: Pre-shared key of WPA.  WPA2: Pre-shared key of WPA2. Encryption: Select the encryption type, including Auto, TKIP, and AES. The default setting is Auto, which can select TKIP (Temporal Key Integrity Protocol) or AES (Advanced Encryption Standard) automatically based on the wireless station's capability and request. AES is more secure than TKIP and TKIP is not supported in 802.11n mode. It is recommended to select AES as the encryption type. Wireless Password: Configure the WPA-PSK/WPA2-PSK password with ASCII or Hexadecimal characters. For ASCII, the length should be between 8 and 63 characters with combination of numbers, letters (case-sensitive) and common punctuations. For Hexadecimal, the length should be 64 characters (case-insensitive, 0-9, a-f, A-F). Group Key Update Period: Specify the group key update period in seconds. The value can be either 0 or 30-8640000 seconds. 14
5.1.3 Wireless Advanced Settings Figure 5-8 Wireless Advanced Settings Beacon Interval: Beacons are transmitted periodically by the device to announce the presence of a wireless network for the clients. Beacon Interval value determines the time interval of the beacons sent by the device. You can specify a value from 40 to 100. The default value is 100 milliseconds. DTIM Period: This value indicates the number of beacon intervals between successive Delivery Traffic Indication Messages (DTIMs) and this number is included in each Beacon frame. A DTIM is contained in Beacon frames to indicate whether the access point has buffered broadcast and/or multicast data for the client devices. Following a Beacon frame containing a DTIM, the access point will release the buffered broadcast and/or multicast data, if any exists. You can specify the value between 1-255 Beacon Intervals. The default value is 1, indicating the DTIM Period is the same as Beacon Interval. An excessive DTIM period may reduce the performance of multicast applications. It is recommended to keep it by default. RTS Threshold: When the RTS threshold is activated, all the stations and APs follow the Request to Send (RTS) protocol. When the station is to send packets, it will send a RTS to AP to inform the AP that it will send data. After receiving the RTS, the AP notices other stations in the same wireless network to delay their transmitting of data. At the same time, the AP inform the requesting station to send data. The value range is from 1 to 2347 bytes. The default value is 2347, which means that RTS is disabled. Fragmentation Threshold: Specify the fragmentation threshold for packets. If the size of the packet is larger than the fragmentation threshold, the packet will be fragmented into several packets. Too low fragmentation threshold may result in poor wireless performance caused by the excessive packets. The recommended and default value is 2346 bytes. 5.1.4 Load Balance By restricting the maximum number of clients accessing the EAPs, Load Balance helps to achieve rational use of network resources. 15
Figure 5-9 Load Balance Load Balance: Disable by default. Click ON to enable the function. After enabling it, you can set a number for maximum associated clients to control the wireless access. Maximum Associated Clients: Enter the number of clients to be allowed for connection to the EAP. The number ranges from 1 to 99. 5.2 Portal Portal authentication enhances the network security by providing authentication service to the clients that just need temporary access to the wireless network. Such clients have to log into a web page to establish verification, after which they will access the network as guests. What's more, you can customize the authentication login page and specify a URL which the newly authenticated clients will be redirected to. Please refer to Portal Configuration or Free Authentication Policy according to your need. 16
Following is the page of Portal. Figure 5-10 Portal Page NOTE: To apply Portal in a wireless network, please go to Wireless→Wireless Settings→SSIDs to enable Portal of a selected SSID. 5.2.1 Portal Configuration Three authentication types are available: No Authentication, Local Password and External RADIUS Server. 17
No Authentication：Users are required to finish only two steps: agree with the user protocol and click the Login button. Local Password：Users are required to enter the preset password, which are saved in the EAP. External RADIUS Server：Users are required to enter the preset user name and password, which are saved in the database of the RADIUS server. The RADIUS server acts as the authentication server, which allows you to set different usernames and passwords for different users. Refer to the following content to configure Portal based on actual network situations.  No Authentication Figure 5-11 Portal Configuration_No Authentication Authentication Type: Select No Authentication. Authentication Timeout: After successful verification, an authentication session is established. Authentication Timeout decides the active time of the session. Within the active time, the device keeps the authentication session open with the associated client. To reopen the session, the client needs to log in the web authentication page and enter the user name and password again once authentication timeout is reached. Select Custom from the drop-down list to customize the parameter. 18
Redirect: Disable by default. Redirect specifies that the portal should redirect the newly authenticated clients to the configured URL. Redirect URL: If you enable the Redirect function, please enter the URL that a newly authenticated client will be directed to. Portal Customization: Select Local Web Portal, the authentication login page will be provided by the built-in web server. The page configured below will be presented to users as the login page.

Figure 5-29 QoS Page 2.4GHz/5GHz: Select the 2.4GHz or 5GHz to show and configure the setting of 2.4GHz or 5GHz. Wi-Fi Multimedia (WMM): By default, WMM is enabled. After WMM is enabled, the device has the QoS function to guarantee the transmission of audio and video packets with high priority. 5.5.1 AP EDCA Parameters AP Enhanced Distributed Channel Access (EDCA) parameters affect traffic flowing from the EAP device to the client station. 32
Figure 5-30 AP EDCA Parameters Queue: Queue displays the transmission queue. By default, the priority from high to low is Data 0, Data 1, Data 2, and Data 3. The priority may be changed if you reset the EDCA parameters. Data 0 (Voice)—Highest priority queue, minimum delay. Time-sensitive data such as VoIP and streaming media are automatically sent to this queue. Data 1 (Video)—High priority queue, minimum delay. Time-sensitive video data is automatically sent to this queue. Data 2 (Best Effort)—Medium priority queue, medium throughput and delay. Most traditional IP data is sent to this queue. Data 3 (Background)—Lowest priority queue, high throughput. Bulk data that requires maximum throughput and is not time-sensitive is sent to this queue (FTP data, for example). Arbitration Inter-Frame Space: A wait time for data frames. The wait time is measured in slots. Valid values for Arbitration Inter-Frame Space are from 1 to 15. Minimum Contention Window: A list to the algorithm that determines the initial random backoff wait time (window) for retry of a transmission. This value cannot be higher than the value for the Maximum Contention Window. Maximum Contention Window: The upper limit (in milliseconds) for the doubling of the random backoff value. This doubling continues until either the data frame is sent or the Maximum Contention Window size is reached. This value must be higher than the value for the Minimum Contention Window. Maximum Burst The Maximum Burst is a AP EDCA parameter that applies only to traffic flowing from the EAP devices to the client station. This value specifies (in milliseconds) the maximum burst length allowed for packet bursts on the wireless network. A packet burst is a collection of multiple frames transmitted without header information. The decreased overhead results in higher throughput and better performance. The valid values are multiples of 32 between 0 and 8192. 33
5.5.2 Station EDCA Parameters Station EDCA parameters affect traffic flowing from the client station to the EAP device. Figure 5-31 Station EDCA Parameters Queue： Queue displays the transmission queue. By default, the priority from high to low is Data 0, Data 1, Data 2, and Data 3. The priority may be changed if you reset the EDCA parameters. Data 0 (Voice)—Highest priority queue, minimum delay. Time-sensitive data such as VoIP and streaming media are automatically sent to this queue. Data 1 (Video)—High priority queue, minimum delay. Time-sensitive video data is automatically sent to this queue. Data 2 (Best Effort)—Medium priority queue, medium throughput and delay. Most traditional IP data is sent to this queue. Data 3 (Background)—Lowest priority queue, high throughput. Bulk data that requires maximum throughput and is not time-sensitive is sent to this queue (FTP data, for example). Arbitration Inter-Frame Space： A wait time for data frames. The wait time is measured in slots. Valid values for Arbitration Inter-Frame Space are from 0 to 15. Minimum Contention Window： A list to the algorithm that determines the initial random backoff wait time (window) for retry of a transmission. This value cannot be higher than the value for the Maximum Contention Window. Maximum Contention Window： The upper limit (in milliseconds) for the doubling of the random backoff value. This doubling continues until either the data frame is sent or the Maximum Contention Window size is reached. This value must be higher than the value for the Minimum Contention Window. 34
TXOP Limit： The TXOP Limit is a station EDCA parameter and only applies to traffic flowing from the client station to the EAP device. The Transmission Opportunity (TXOP) is an interval of time, in milliseconds, when a WME client station has the right to initiate transmissions onto the wireless medium (WM) towards the EAP device. The valid values are multiples of 32 between 0 and 8192. No Acknowledgement： Select Enable to specify that the EAP device should not acknowledge frames with QosNoAck as the service class value. By default, it is disabled. Unscheduled Automatic Power Save Delivery： Select Enable to enable APSD, which is a power management method. APSD is recommended if VoIP phones access the network through the EAP device. By default, it is enabled. 5.6 Rogue AP Detection A Rogue AP is an access point that has been installed on a secure network without explicit authorization from a system administrator. The EAP device can scan all channels to detect all APs in the vicinity of the network. If rogue APs are detected, they are shown on the Detected Rogue AP List. If an AP listed as a rogue is legitimate, you can add it to the Trusted AP List. 35

Chapter 7 Management Management page is mainly used for device management and maintenance. 7.1 System Log System log records information about hardware, software as well as system issues and monitors system events. With the help of system log, you can get informed of system running status and detect the reasons for failure. Following is the page of System Log. Figure 7-1 System Log Page 49
7.1.1 Log List From Log List you can view detailed information about hardware, software, system issues and so on. Figure 7-2 Log List 7.1.2 Log Settings You can choose the way to receive system logs in Log Settings zone, where these parameters can be configured: Enable Auto Mail, Enable Server and Enable Nvram. Figure 7-3 Log Settings 50
 Enable Auto Mail If Auto Mail Feature is enabled, system logs will be sent to a mailbox. The following content will be shown. Figure 7-4 Enable Auto Mail From: Enter the sender’s email address. To: Enter the recipient’s email address, which will receive the system logs. SMTP Server: Enter the IP address of the SMTP server. Enable Authentication: Generally users are required to log in to the SMTP server by entering user name and password.  User Name: Enter the sender’s email address.  Password: Enter the password of the sender’s email address.  Confirm Password: Enter the password again for confirmation. Time Mode: System logs can be sent at specific time or time interval.  Fixation Time: Set a fixed time, for example, 15:00. The recipient will receive the system logs sent by the device at 15:00 every day.  Period Time: Set a time interval, for example, 5 hours. The recipient will receive the system logs sent by the device every 5 hours.  Enable Server System logs can also be sent to a server. After Enable Server is enabled, the following content will be shown. 51
Figure 7-5 Enable Server System Log Server IP: Enter the IP address of the remote server. System Log Server Port: Enter the port of the remote server.  Enable Nvram By default, Nvram is disabled. Check the box to enable Nvram, system logs will be saved after power supply is cut. Nvram (Non-volatile Random Access Memory) is a RAM that can still save data even if a device is power off. All TP-Link EAPs are equipped with Nvram. With this option enabled, the Nvram feature can help reserve the system logs when an EAP device is power off. 7.2 Web Server You can log in web management interface, thereby manage and maintain the device. Following is the page of Web Server. Figure 7-6 Web Server Page HTTPS: HTTPS (Hypertext Transfer Protocol Secure) is enabled by default. Secure Server Port: Designate a secure server port for web server in HTTPS mode. By default the port is 443. 52
Server Port: Designate a server port for web server in HTTP mode. By default the port is 80. Session Timeout: Set the session timeout time. If you do nothing with the web management page within the timeout time, the system will log out automatically. Please login again if you want to go back to web management page. 7.3 Management Access Management Access Control allows you to configure up to four MAC addresses of the hosts that are allowed to log in to the web management page of the EAP. Click Add PC’s MAC and the MAC address of the current host will be added to MAC address list. Following is the page of Management Access. Figure 7-7 Management Access Page MAC Authentication: Check the box to enable MAC Authentication.

All PCs in LAN can log in and manage the device. MAC1~MAC4: Enter the MAC addresses of the PCs which are authorized to log in the device. 7.4 LED ON/OFF Following is the page of LED ON/OFF. By default the LED is on. 53
Figure 7-8 LED ON/OFF 7.5 SSH This device supports the SSH Server function that allows users to login and manage it through SSH connection on the SSH client software. SSH (Secure Shell) is a security protocol established on application and transport layers. SSH-encrypted-connection is similar to a telnet connection, but essentially the old telnet remote management method is not safe, because the password and data transmitted with plain-text can be easily intercepted. SSH can provide information security and powerful authentication when you login this device remotely through an insecure network environment. It can encrypt all the transmission data and prevent the information in remote management from being leaked. Following is the page of SSH. Figure 7-9 SSH Page Server Port: Enter the server port. By default, it is port 22. SSH Login: Check the box to enable SSH Server. By default, it is disabled. 54
7.6 Management VLAN Management VLAN provides a safer way for you to manage the EAP. With Management VLAN enabled, only the hosts in the management VLAN can manage the EAP. Since most hosts cannot process VLAN TAGs, connect the management host to the network via a switch, and set up correct VLAN settings for the switches on the network to ensure the communication between the host and the EAP in the management VLAN. Following is the page of Management VLAN. Figure 7-10 Management VLAN Page Management VLAN: Enable Management VLAN. Management VLAN ID: Specify the Management VLAN ID. The valid values are from 1 to 4094. 7.7 SNMP The device can be configured as an SNMP agent. SNMP (Simple Network Management Protocol), the most widely applied network management protocol, provides a management framework to monitor and maintain Internet devices. Main functions of SNMP include monitoring network performance, detecting and analyzing network error, configuring network devices, and so on. When networks function properly, SNMP can perform the functions of statistics, configuration and testing. When networks have troubles, SNMP can detect and restore these troubles. An SNMP consists of three key components: manager, agent and MIB (Management Information Base). SNMP manager is a client program operating at workstation, assisting network administrators to accomplish most network device management tasks. An agent is a network-management software module that resides on a managed device and responsible for receiving and dealing with data sent by managing device. Generally the 55
managed devices are network devices including hosts, bridges, switches and routers. MIB is the collection of managed devices. It defines a series of properties of the managed devices. Every SNMP agent has its own MIB. Once the device has become an SNMP agent, it is able to receive and process request messages from SNMP manager. Following is the page of SNMP. Figure 7-11 SNMP Page SNMP Agent: Enable SNMP Agent and the SNMP Agent will collect the information of this device and respond to information requests from one or more management systems. SysContact: Enter the textual identification of the contact person for this managed node. SysName: Enter an administratively-assigned name for this managed node. SysLocation: Enter the physical location of this managed node. Get Community: Community refers to a host group aiming at network management. Get Community only has the read-only right of the device's SNMP information. The community name can be considered a group password. The default setting is public. Get Source: Defines the IP address (for example, 10.10.10.1) or subnet for management systems that can serve as Get Community to read the SNMP information of this device. The format of subnet is “IP address/bit” (such as 10.10.10.0/24). The default is 0.0.0.0, which means all hosts can read the SNMP information of this device. 56
Set Community: Set Community has the read and write right of the device's SNMP information. Enter the community name that allows read/write access to the device's SNMP information. The community name can be considered a group password. The default setting is private. Set Source: Defines the IP address (for example, 10.10.10.1) or subnet for management systems that can serve as Set Community to read and write the SNMP information of this device. The format of subnet is “IP address/bit” (such as 10.10.10.0/24). The default is 0.0.0.0, which means all hosts can read and write the SNMP information of this device. NOTE: Defining community can allow management systems in the same community to communicate with the SNMP Agent. The community name can be seen as the shared password of the network hosts group. Thus, for the security, we suggest modifying the default community name before enabling the SNMP Agent service. If the field of community is blank, the SNMP Agent will not respond to any community name. 57
Chapter 8 System System page is mainly used to configure some basic information like user account and time, and realize functions including reboot, reset, backup, restore and upgrade the device. 8.1 User Account You can change the username and password to protect your device from unauthorized login. We recommend that you change the default user password on the very first system setup. Figure 8-1 User Account Page Old User Name/Password: Enter the present user name and password of the admin account to get the permission of modification. New User Name/Password: Enter a new user name and password for the admin account. Both values are case-sensitive, up to 64 characters and with no space. New Password must not be "admin" Confirm New Password: Enter the new password again. 8.2 Time Settings System time represents the device system’s notion of the passing of time. System time is the standard time for Scheduler and other time-based functions. You can manually set 58
the system time, configure the system to acquire its time settings from a preconfigured NTP server or synchronize the system time with the PC’s clock. The device supports DST (Daylight Saving Time).
