The TCP/IP address ranges for printer detection can be entered here. Two methods for automatic recognition of the network printing systems are available.

For recognition of the network printing systems, please enter the TCP/IP addresses or address ranges into the input fields of your preferred detection method. For accepting your configuration settings please click the 'Apply' button.


Source Identifier

Chose the desired source identifier here for which you want to configure the following parameters. Please note that network ranges and IP addresses for printer detection of source identifiers must not overlap.


Schedule

Within this panel it can be specified which timeframes and time intervals should be used from the FSM client software for automatic search of new printing systems within the configured TCP/IP addresses or address ranges, and whether new recognized printing systems should be automatically monitored by the FSM client software.

By clicking the 'Search now
' button, an immediate search and detection process can be initiated.


SNMP v3 Credentials

Here you define user names for use with SNMP v3. A user name represents a set of parameters and passwords which can be used in several network ranges.

For authentication at the printer chose the appropriate authentication protocol
and enter the password for it. Also chose the required encryption protocol and enter that password as well. This set of parameters is defined by the user name. Please be aware that communication with the printers will be working only if these parameters fit the settings at the printer.

Using the button 'Add
' you may add several sets of credentials into the list of user names and select these when setting up a network range for printer detection.


Network Ranges

Here you define networks and network ranges, in which the FSM client will search for printers. A network is defines by its IP address and its subnet mask. Within a network, a finite number of host addresses exists. Example:

Host address:   192.168.178.100     
Network address:   192.178.178.0     
Subnet mask:   255.255.255.0     

The address in the example above describes a class C network. The beginning part with 192.168.178 - built of 3 bytes - always remains constant, while the last byte addresses from 1 to 254 devices. Values 0 and 255 are reserved. The constant part is the network address, consisting of 3 bytes, that is 24 bit. This allows writing the network address using 2 different notations:

Network address:   192.168.178.0     
Subnet mask:   255.255.255.0     

or using the CIDR notation (Classless Inter-Domain Routing) :

Network address:   192.168.178.0 / 24  

More examples for CIDR notation and subnet masks:

CIDR   Subnet mask      Available host addresses  
/8       255.0.0.0       max. 16.777.214  
/12       255.240.0.0       max. 1.048.574  
/16       255.255.0.0       max. 65.534  
/20       255.255.240.0       max. 4094  
/21       255.255.248.0       max. 2046  
/22       255.255.252.0       max. 1022  
/23       255.255.254.0       max. 510  
/24       255.255.255.0       max. 254  
/25       255.255.255.128    max. 126  
/26       255.255.255.192    max. 62  
/27       255.255.255.224    max. 30  
/28       255.255.255.240    max. 14  
/29       255.255.255.248    max. 6  
/30       255.255.255.252    max. 2  

Chose the scan method. A broadcast usually will only work if FSM Client and printers are residing in the same network. The broadcast has the advantage of sending out one data packet only to make all devices answer. In case a network is attached via a router, it is most probable that this router will block broadcasts into this network. Then you have to use Scan method. This will address all possible host addresses explicitly. Answering a broadcast by devices is not guaranteed.

Using Scan
method, the number of addressed devices might be reduced by restricting the search range. Therefore enter a From IP address and a To IP address. The search then will only go through this restricted range of addresses.

Then enter the network address
of the network. Your network administrator will give you the corresponding subnet mask or CIDR number. One of both will be sufficient to enter, the other one will be calculated automatically.

Searching sends an UDP package for printer identification and waits for a response of the potential printing system. Usually printers answer on SNMP queries made on UDP port
161. If you want to detect SNMP Extenders for local printers set the UDP port to 51950. The buttons 'Std.' and 'Ext.' will set the content of the UDP port edit field to the required value.

Chose the SNMP version to be used. With v1/v2 a community
name is required. This usually is set to public, if not configured different at printer. You might have to change the name here to fit to printer configuration. With SNMP v3 a user name and a context name is required. The user name references a set of credentials which are configured separately in panel SNMP v3 credentials. SNMP v3 transfers data and authentication passwords encrypted. With option v1/v2/v3, first a communication with the printer via v3 is tried, if that is not answered, v1/v2 will be used.

Using the button 'Add
' you may add several partial ranges of one network as also several complete networks.
