3. Configuring the AMU Note: The following terms are used interchangeably in this chapter: 2411EZYLINK-9 and AirEZY, Base Radio Transceiver and Server, Client Radio Transceiver and Client. Features and Theory of Operation of AMU The AMU supports the following features: • Multiple (up to 4) AirEZY servers flow control Due to the discrepancy of the transmission speed for Ethernet port (10 MB) and transceiver port (1.2 MB to 5.
If a single server is used, the AMU also supports client bridging provided the option is selected. The client bridging allows clients under the same server to communicate with each other based on MAC address via an AMU. With Ethernet bridging, the packet forwarding only happens between the two Ethernet ports in the AMU (i.e.: packets received from a interface would not be transmitted over the same interface, even the address table indicates that the destination is on the same Ethernet port).
Step 2: Use the EthA IP address as the URL in the browser: Type in http://192.168.169.170 , and hit the Return key. Step 3: The browser will prompt for user id (pre-configured default id is airezy)and password (preconfigured default password is adairezy). Once correct user id and password is received, the browser displays all the information related to the AMU and associated base radio transceivers.
0) 1) 2) 3) 4) Display Configuration Configure Bridge Configure Router Reboot AMU Exit This will allow telnet user to configure the AMU without using a browser or a SNMP manager. If 0 is the input, the current AMU configuration is displayed. If 1 is the input, a user will be prompt to input IP address and network mask for EthA, and default gateway IP address. The input shall use a.b.c.d notation for IP address.
4. Configuring, Monitoring the Base Radio Transceiver (the Server) and the Client Radio Transceiver (the Client) Note: The following terms are used interchangeably in this chapter: 2411EZYLINK-9 and AirEZY, Base Radio Transceiver and Server, Client Radio Transceiver and Client. Similar to that for modifying the default configuration of the AMU, there are two approaches to configure and monitor the AirEZY servers and clients.
There are two types of users defined: “ADMIN”, and “READ”. The ADMIN user has the privilege to view and modify the AMU, the server and the client configurations. The ADMIN user also has the privilege to add, modify, or delete users. The READ user may only view AMU, server and client configuration. There are two default users configured with AMU: an ADMIN user, and a READ user. The ADMIN user is assigned “airezy” as the user id, and “adairezy” as the password.
Figure 1. Web Interface Login Screen When Change Password button is clicked, the user will be requested to enter the old password and the new password. The new password shall be entered twice to ensure the user entered correctly. Figure 2.
Clicking the Submit button will update the password file in the AMU if both Password and the two New Passwords are entered correctly, and the user will be prompt to login. If updating password operation is unsuccessful, the user will be asked to re-enter all the fields. 4.1.3 Display Views for AMU and Servers Once the correct user id and password are entered and AirEZY Control button is selected, the AMU web interface presents a graphical representation of the AMU and Servers (Base Radio Transceivers).
Figure 4. Web Interface - Detailed AMU Information Screen The AMU Information table contains networking related configuration about the AMU. The Server List table contains all the servers known to the AMU. The number of servers in the table could be 0 to 4. A user may modify any field in the AMU information table by double clicking the value of that field; the user is prompted to enter a valid value for the field. Once the correct value is entered, user may click the Submit button.
and clicking Select Server button to view details of the server. A user may modify any fields with modifiable property marked “yes” in the table. To change any of the modifiable fields, double click the value of the field, the user is prompted to enter a valid value for the field. Once the correct value is entered, user may click the Submit button. User may abort the modification by click the Cancel button. Note: In order to allow any of the IP address changes to take place, the AirEZY AMU must be rebooted.
Figure 6. Web Interface – Detailed Server Information Screen Certain fields in the server information table can be modified by double clicking that field. One can also double clicking a particular client number in the client list to view the detailed information about that client, as shown in Figure 7. The Set Auto Monitor button is used to activate monitoring a server unit statistics automatically.
Total Octets Received (in) Total ACK Packets (out) Total Retransmission (out) No No No It indicates the number of octets received by the server unit since last retrieval. It indicates the number of acknowledgement packets sent out by the server unit since last retrieval. It indicates the number of packet retransmissions sent out by the server unit since last retrieval. A user may modify any fields with modifiable property marked “yes” in the table.
A user may select a client in the client list shown in Fig. 6 and click the Select Client button, or double click a client icon in Figure 5, the detailed information about the client is also displayed. Figure 8. Web Interface – Detailed Client Information Screen The following table describes the fields contained in the Detailed Client Information Screen.
(out) client unit since last retrieval. A user may modify any fields with modifiable property marked “yes” in the table. To change any of the modifiable fields, double click the value of the field; the user is prompted to enter a valid value for the field. Once the correct value is entered, user may click the Submit button. User may abort the modification by click the Cancel button.
4.2 Using an External SNMP Manager 4.2.1 Access to SNMP Agent The SNMP agent, by default, is not configured to interact with any other external SNMP manager for security reasons. If an external SNMP manager is desired, the file /etc/snmp/snmpd.conf must be modified to include the host IP address of the SNMP manager. Example of /etc/snmp/snmpd.conf #### # First, map the community name (COMMUNITY) into a security name # (local and mynetwork, depending on where the request is coming # from): # sec.
2) Server Object • Once Server Discovery object has been retrieved (via SNMP GET operation), server objects may be manipulated via GET, SET operations. 3) Polling List Objects • After a server object has been retrieved, the polling list of the server may be retrieved and modified.
• Polling list and server has one to one relationship. That is to say, server instance n contains the polling list represented by polling list instance n (where n has a range of 1 to 4). • When perform SNMP SET operation on a polling list, the SNMP manager must send the updated and complete polling list in the above format in order for the server to poll the clients properly.
4.3 AMU Web User Administration The AMU provides web user administration utility in addition to configuration and monitoring capability of AIREZY server and clients. This utility allows a system administrator to add users, and delete users. To login web user administration utility, the User Admin button must be clicked in the User Login Screen (Figure 1. Web Interface Login Screen).
Figure 10. Web Interface – Add a User Once Submit button is clicked after the form is filled out correctly, the information will be saved. When deleting a user is required, the Delete User button must be used on the side bard. Figure 11.
Once a user is selected by high-lighting, clicking OK button will erase the highlighted user information from the AMU. Login button on the side bar allows a user to restart the login process.
