1 Overview Device Manager is a device management application that lets you manage Allied Telesis' hubs, switches and routers using Simple Network Management Protocol (SNMP). You can perform various operations on the devices from an intuitive graphical user interface. Since Device Manager is written in Java, it runs on multiple platforms, including Windows, Solaris and HP-UX, and provides a common look and feel on all supported platforms.
2 Starting Device Manager Device Manager can be started in two ways, from the command line or from a network management application. When started, Device Manager identifies the target device after you enter its IP address. Device Manager will then display the main panel of that device. Note - In Windows environments, Device Manager can also be launched from the Start menu or from the Run command in the File menu.
2.1 Starting From the Command Line The command line interface is the most basic way to start Device Manager. Topics: • • • • • • • • • • • • • • • Command Syntax Target Host SNMP Version Get Community Set Community Trap Community Titlebar String User Account Name Security Level Authentication Protocol Authentication Password Privacy Protocol Privacy Password Trap Version Parameter File 2.1.1 Command Syntax To start Device Manager from the command line, use the following syntax.
DisplayName Titlebar string. UserName User account name to be used for accessing the MIB. This is required when using SNMPv3. SecLevel Security level that is configured for the User Name. This is required when using SNMPv3. AuthProtocol Authentication protocol that is configured for the User Name. This is required when using SNMPv3. AuthPassword Authentication password that is configured for the User Name. This is required when using SNMPv3.
Examples: devicemanager -TargetHost 172.16.99.123 -SnmpVersion 1 devicemanager -TargetHost 172.16.99.123 -SnmpVersion 2 2.1.4 Get Community Get Community is an SNMP community string used to get MIB values from the agent. You must specify the same community string as the one configured on the target host. If the string is not specified, the default community string "public" is used. Examples: devicemanager -TargetHost 172.16.99.
2.1.7 Titlebar String You can specify a string to display on the titlebar. Example: devicemanager -TargetHost dvcmgrhub -DisplayName dvcmgr 2.1.8 User Account Name If you specified 3 (SNMPv3) for the SNMP Version, you must also specify a User Account Name that is already configured on the target host. Examples: devicemanager -TargetHost 172.16.99.123 -SnmpVersion 3 -UserName AlliedView -SecLevel noAuthNoPriv devicemanager -TargetHost 172.16.99.
Examples: devicemanager -TargetHost 172.16.99.123 -SnmpVersion 3 -UserName AlliedView -SecLevel authNoPriv -AuthProtocol MD5 -AuthPassword PASS1234 devicemanager -TargetHost 172.16.99.123 -SnmpVersion 3 -UserName AlliedView1 -SecLevel authNoPriv -AuthProtocol SHA -AuthPassword PASS1233 2.1.
2.1.13 Privacy Password If you specified 3 (SNMPv3) for the SNMP Version, and your Security Level is authPriv, you must specify a Privacy Password that is configured for the User Account Name on the target host. Examples: devicemanager -TargetHost 172.16.99.123 -SnmpVersion 3 -UserName AlliedView -SecLevel authPriv -AuthProtocol MD5 -AuthPassword PASS1234 -PrivProtocol DES -PrivPassword PASS5678 devicemanager -TargetHost 172.16.99.
2.1.15 Parameter File Option parameters can be written in a file and can be used by Device Manager to access the device. The parameter file is a plain text file which contains a name-value pair on each line. Example: devicemanager -TargetHost H3600 @para1.txt where para1.txt is: -SetCommunity set -GetCommunity get -Displayname TEST 2 Starting Device Manager AlliedView™-EMS 3.
2.2 Starting From a Network Management Application Device Manager can be started from an integrated network management application. Topics: • • • • Starting From Castle Rock SNMPc Starting From HP OpenView Network Node Manager Starting From IBM Tivoli NetView Starting From Ipswitch WhatsUp AlliedView™-EMS 3.
2.2.1 Starting From Castle Rock SNMPc To start Device Manager from SNMPc, double-click on a node icon on the map window. If the node is supported by Device Manager, the main panel of the node is displayed. Note that Device Manager and SNMPc run independently of each other, so exiting SNMPc has no effect on Device Manager. Device Manager continues to run even after SNMPc stops running. To exit Device Manager, select Exit from its File menu.
2.2.2 Starting From HP OpenView Network Node Manager To start Device Manager from HP OpenView, select a node on the map window, then select AlliedView-EMS > Device Manager from the Tools menu.

The window has some common components regardless of the information displayed. This section describes operations which are common for all such MIB variable windows.
MIB Variable Window 6 MIB Variable Window AlliedView™-EMS 3.
6.1 Table Tab In the Table tab, MIB variables are displayed in a table. This is the default tab opened by a menu item. Values in the table are updated at each polling interval. Note - The type of variables displayed determines which kind of tabs are displayed and which are not. For example, chart tabs are not displayed when you are only viewing string variables.
6.1.1 Transpose Button : flips rows and columns. 6 MIB Variable Window AlliedView™-EMS 3.
6.2 Plot Chart Tab In the Plot Chart tab, variables are displayed as a graph. To the right of the graph is a table of the numeric variables which can be displayed in the graph. Variables selected in the table are plotted on the graph. The scale of the vertical axis is automatically adjusted according to the values of the variables. The graph is updated at each polling interval. Note - The polling interval can be changed in the Options tab. When you resize the window, the graph is resized accordingly.
The components of the Plot Chart tab are discussed below. 6.2.1 Graph The left half of the window contains the graph showing the values of the selected variables. The vertical (Y) axis shows the values and the horizontal (X) axis shows time. New values are plotted when Device Manager gets them, at the predefined polling interval. The scale of the X-axis is automatically adjusted according to the number of values plotted. The X-axis can display a maximum of the latest 20 values.
Note - Displaying many variables at the same time imposes a load on system resources. If you encounter delay or reduced system performance, reduce the number of variables displayed, or increase the polling interval. To reduce the number of variables, uncheck some variables in the MIB variable table. To increase the polling interval, click the Options tab and change the Polling Interval. 6 MIB Variable Window AlliedView™-EMS 3.
6.3 Bar Chart Tab The Bar Chart tab displays variables as a bar chart. To the right of the graph is a table of the numeric variables which can be displayed in the chart. Only variables selected in the table are displayed in the chart. The scale of the vertical axis is automatically adjusted according to values of the variables displayed. The chart is updated at the polling interval. Note - The polling interval can be changed in the Options tab. When you resize the window, the chart is resized accordingly.
The components of the Bar Chart tab are discussed below. 6.3.1 Chart In the left half of the window is the chart showing the values of the selected variables. The vertical (Y) axis shows the values and the horizontal (X) axis shows the variable name or number. You can select whether to display the name or the number in Option > Option > Other. Each variable is shown with a different color. The colors of the variables are displayed between the chart and the variable table.
Note - Displaying many variables at the same time imposes a load on system resources. If you encounter delay or reduced system performance, reduce the number of variables displayed, or increase the polling interval. To reduce the number of variables, uncheck some variables in the MIB variable table. To increase the polling interval, click the Options tab and change the Polling Interval. 6 MIB Variable Window AlliedView™-EMS 3.
6.4 Edit Tab In the Edit tab, you can change the value of any variable with read-write access. All variables are displayed in a table. For variables which can be changed, a checkbox is displayed in the first column. To change a value, input or select a new value in the MIB Value column, check the variable, then click the Set MIB Value button.
6.4.1 Checkbox Column The first (leftmost) column shows whether or not the variable can be changed (i.e. the variable supports the SNMP Set operation). If a checkbox is displayed in the column, the variable's value can be changed. When you change several variables, set the new values in the Value column and then check all corresponding boxes. Device Manager sends new values for selected variables in a batch. 6.4.2 MIB Variable Column MIB variable names are displayed. 6.4.
6.4.8 Set MIB Value Button : Changes the values of the checked variables, using the SNMP Set operation. The values in the MIB Value fields are sent to the SNMP agent on the device. Note - SNMPv3: Depending on the WRITE VIEW access settings of the User Account Name used, there is a possibility that Device Manager may not be able to set some MIB values. When this happens, a "No access error." value will be displayed on the affected MIB Value cells.
To set a threshold, enter a threshold value in the Value field, then click OK. Note that this specifies a rising threshold which triggers an event when the variable's value increases to exceed the threshold, i.e. crosses the threshold from below. When the threshold is reached, a pop-up message is displayed or a predefined command is executed. You can select which action is executed in the Option > Option > User Action tab.
6.5 Options Tab In the Options tab, preferences specific to the MIB variable windows can be changed. Topics: • • • • • • Polling Interval Display Data Type of Chart Regist Menu Save Polling Data Start Snapshot Default Button Options tab 6.5.1 Polling Interval Specifies the polling interval. The valid range is 5 seconds to 3600 seconds (1 hour). However, a short polling interval may reduce system performance. Care must be taken to set an appropriate value for your system. 6.5.
Absolute Displays a value as it is. Relative Displays a change in the value per second. This is (Current value - Previous value) / Polling Interval. Note - The change here takes effect the next time the data is polled. 6.5.3 Regist Menu Add this window to the User Menu. If you want to view the current window repeatedly, do the following. 1. Click "Regist menu". 2. On "Regist Menu Item" dialog box, select one of "Common Menu" or "Target Menu".
