Basic configuration of the web application
Increasing the reliability of network connections through link aggregation
In the default settings, both network interfaces can be used at the same time to access the web application from two different network segments, for example.
To increase the reliability, the network interfaces can be grouped through link agg-
regation. Only one interface is active within the group. Another interface only becomes active if the active interface fails.
We provide two different modes to monitor the interfaces:
MII mode:
The carrier status of the network interface is monitored through the
Media Independent Interface. This mode only checks the function of the network interface.
ARP mode:
The address resolution protocol sends requests to an ARP target within the network. The answer of the ARP target confirms both the functionality of the network interface and the proper network connection to the ARP target.
If the ARP target is connected to the network but is temporarily offline, requests cannot be answered. Define multiple ARP targets to receive an answer from at least one target if an ARP target fails.
NOTE: MII
and
ARP mode
cannot be combined.
How to configure the settings of grouped network interfaces:
NOTE:
According to RFC 3330, the Link Local address space 169.254.0.0/16 is reserved for the internal communication between devices. An IP address of this addres space cannot be assigned.

Updating the stored SSL certificate
An SSL-secured connection connects the web browser to the web application. The device on which the web application is operated stores an SSL certificate, which enables the user or the web browser to authenticate the opposite site.
If the device’s IP address differs from the IP address given in the certificate, the web browser sends a message. It is therefore recommended to import an individual certificate in order to ensure that the device IP address complies with the IP address given in the certificate.

User authentication against directory services
In in-house networks, the user accounts of different users are often administrated by a directory service. The device can access such a directory service and authenticate users against the directory service.
NOTE:
If the Admin user account cannot be authenticated by the directory service, the user account is authenticated by the device’s data base.
The directory service is exclusively used to authenticate a user. The user rights are assigned within a database of the KVM system. The following paragraphs describe the different scenarios:
The user account exists within the directory service and the KVM system
The user can log in with the password stored in the directory service. After the login, the user is assigned with the rights of the correspondent account in the
KVM system.
NOTE:
The password which the user used to log in, is taken over into the database of the KVM system.
The user account exists within the directory service, but not within the KVM system
A user that has been successfully authenticated against the directory service, but does not have an account of the same name within the database of the KVM system, is assigned with the rights of the RemoteAuth user.
If required, change the rights of this particular user account to set the rights for users without a user account.
ADVICE:
Deactivate the RemoteAuth user to prevent users without user accounts to log in to the KVM system.
The user account exists within the KVM system, but not within the directory service
If the directory service is available, it reports that the user account does not exist.
The access to the KVM system is denied to the user.
G&D DL-Vision(M/S) · 27
Network functions of the devices
If the server is not available, but the fallback system is active (see below), the user can log in with the password that is stored within the KVM system.
IMPORTANT:
Mind the following safety instructions to prevent a locked or deactivated user from logging in to the system in case the connection to the directory service fails:
If a user account is deactivated or deleted in the directory service, this action can also be carried out within the user database of the KVM system.
Only activate the fallback system in reasonable exceptional cases.
How to configure the user account authentication:
NOTE:
If no directory service is applied, the user accounts are administered by the device.

Monitoring functions
The current monitoring values of all devices within the KVM system can be viewed in the device-specific branches (e.g. KVM matrix systems) as well as in the KVM Combina-
tions and Critical Devices branches of the tree view.
The various information regarding a device can either be displayed in individual val-
ues or in monitoring groups, which are sorted according to topic. The following exemplary figure shows the Status values and three different monitoring groups:
Figure 2: Detailed view of an exemplary monitoring table
Individual values (the Status value in the figure above) immediately show if the status is correct (green) or deviating from the normal operating value (red). The text in the column also provides information about the current status.
Monitoring groups allow you to group various individual values. The column of a monitoring group shows if all values are within range (OK) or if at least one value is deviating from the normal operating values (Error).
Clicking the arrow in the column opens a separate window, which displays the individual values of the group.

Viewing monitoring values
NOTE:
An overview of the possible monitoring values of all different device types
By applying different monitoring sets, the monitoring values are displayed in the different branches of the tree view.
Several branches (e.g. Critical devices) provide another view to enable the user to detect critical monitoring values as fast as possible.
Listing values by applying monitoring sets
A monitoring set defines which individual values and groups are to be displayed.
The column, which shows the individual values, enables you to read the status and check whether it is deviating from the normal operating values.
Monitoring groups allow you to group various individual values. The column of a monitoring group shows if all values are within range (OK) or if at least one value is deviating from the normal operating values (Error).
Clicking the arrow in the column opens a window, which contains detailed information regarding the individual values of the group.
ADVICE:
The following pages of this chapter provide detailed information regarding monitoring groups and monitoring sets.
Listing individual values of critical devices
If a device shows a value that deviates from the normal operating values, the device is additionally listed in the Critical devices branch. This branch displays all deviating
(red) values in tabular form. This way, deviating values can be detected as fast as possible.
NOTE:
To be able to find deviant values as fast as possible, monitoring sets are not applied here.
Disabling the monitoring values
Any monitoring value can be disabled. After disabling, the monitoring values are no longer shown in the web application.
IMPORTANT:
Critical values are no longer shown for any disabled values.
How to enable/disable the monitoring values:

Marking the messages from a critical device as read
Many messages require immediate actions from the administrator. Other messages
(e.g. the break-down of the redundant power supply), however, point to possibly uncritical conditions.
In such a case, all peculiar values of a device can be marked as read, which causes the following:
A device whose deviating values have been marked as read shows no blinking status bar.
The cells, info dialogs, and monitoring windows of all “read” devices are highlighted in yellow.
If a monitoring group contains critical values, which have been marked as read, the column displays Error. In addition, the cell is highlighted in yellow.
NOTE:
The system only highlights values that have been deviating from the normal operating values at the time the function has been executed. The web application shows if another monitoring value of such a device deviates from the normal operating values.
How to mark the Monitoring messages of a device as read:
1. Click on the

Practical use of the SNMP protocol
A Network Management System (NMS) is used to monitor and control computers and network devices. The system queries and collects data from the agents of the monitored devices.
NOTE:
An Agent is a program, which runs on the monitored device and detects its status. Via SNMP, the detected data are transmitted to the Network Management System.
If an Agent detects a severe failure within the device, it can send a Trap packet to the
Network Management System. This way, the administrator is directly informed about such occurrences.
Configuring the SNMP agent
How to configure the SNMP agent:
1. Use the tree view to click on
KVM Extenders > [All extenders]
.
2. Right-click the device to be configured. Now click the
Configuration
entry in the context menu.
3. Click the
Network> SNMP Agent
tabs.
4. Enter the following data in the Global paragraph:
Status:
Protocol:
Port:
SysContact:
SysName:
SysLocation:
Select the particular entry to either switch the SNMP agent off (
Off
) or on (
Enabled
).
Select the protocol (
TCP
or
UDP
) – normally UDP – via which the SNMP packets are to be transmitted.
Define the port – normally 161 – on which the incoming
SNMP packets are to be accepted.
Enter the admin’s contact data (e.g. direct dial or email address).
Enter the device name.
Enter the location of the device.
5. If you want to process the packets of the
SNMPv2c
protocol version, enter the following data in the paragraph of the same name:

Users and Groups
Efficient rights administration
The web application administrates up to 256 user accounts as well as the same amount of user groups. Any user within the system can be a member of up to 20 groups.
The user accounts and the user groups can be provided with different rights to operate the system.
ADVICE:
The rights administration can almost be carried out completely through user groups. Therefore, the user groups and the assigned rights have to be planned and implemented beforehand.
This way, the user rights can be quickly and efficiently changed.
The effective right
The effective right determines the right for a particular operation.
IMPORTANT:
The effective right is the maximum right, which consists of the user account’s individual right and the rights of the assigned group(s).
EXAMPLE:
The user JDoe is member of the Office and TargetConfig groups.
The following table shows the user account rights, the rights of the assigned groups, and the resulting effective right:
Right
Target config
Change own password
Target access
User
JDoe
No
No
Group
Office
No
Yes
Group
TargetConfig
Yes
No
Effective right
Yes
Yes
Full
View No

The settings of the Target config and Change own password rights result from the rights assigned to the user groups. The Target access right which, in this case, enables full access, was given directly in the user account.
The dialogue windows of the web application additionally display the effective right for every setting.
ADVICE:
Click the
Details
button to get a list of the groups and rights that are assigned to the user account.

Users and Groups
Efficient user group administration
User groups enable the creation of a shared right profile for several users with identical rights. Furthermore, the user accounts that are included in the member list can be grouped and therefore no longer have to be individually configured. This facilitates the rights administration within the matrix system.
If the rights administration takes place within the user groups, the user profile only stores general data and user-related settings (key combinations, language settings, …).
When initiating the matrix system, it is recommended to create different groups for users with different rights (e. g., »Office« and »IT«) and assign the respective user accounts to these groups.
EXAMPLE:
Creat more groups if the user rights are to be further divided. If, for example, some users of the »Office« group are to be provided with the multi-access right, a respective user group can be created:
Create a user group (e. g., »Office_MultiAccess«) with identical settings for the »Office« group. The multi-access right is set to full. Assign the respective user accounts to this group.
Create a user group (e. g., »MultiAccess«) and only set the multi-access right to Yes. In addition to the »Office« group, also assign the respective user accounts to this group.
In both cases, the user is provided with the full effective right for multi-access.
ADVICE:
The user profile offers the possibility to provide extended rights to a group member.
Administrating user accounts
User accounts enable you to define individual rights for every user.
IMPORTANT:
The administrator and any user that holds the Superuser right are permitted to create and delete user accounts and edit rights and user-related settings.

Support for special Multimedia and Sun keys
Various manufacturers added special keys to the standard keyboards.
Some keyboards are provided with multimedia keys through which it is possible to comfortably operate special multimedia functions of the computer. For example, the keyboard of the Apple Mac mini is provided with a key to open the DVD drive.
Compared to standard keyboards, Sun desktops and servers are provided with separate keys (Solaris Shortcut Keys) to operate special system functions. After the keyboard mode for Sun desktops and servers has been activated, the Solaris Shortcut Keys can be used at the console. If the console only provides a standard keyboard, several key combinations can be applied to emulate the Solaris Shortcut Keys (see page 81).
Several USB keymodes are provided to use the special keys of such keyboards.
