Important aspect for Discovering or getting information about Networking Devices such as Printer is to troubleshoot connection from source to devices and identify attributes configured on printer.
I am using SNMP Tester Tool to identify OID/MIB that can be used to gather custom attributes from Printer.
Following are key components to consider during printer troubleshooting -
- MIB/OID -MIB (Management Information Base) and OID (objects) is actual objects which we can read from Printers.
- These might differ with Printer’s Manufacture.
e.g. OID may looks like 1.3.6.1.4.1.11.2.3.9.4.2.2.17
- UDP 161 ports status between Source and Printer-UDP send datagrams and there are no guarantees of responses.
- Community String-It’s kind of Password. SNMP1/2 requires one parameter (password) as Community string (no ID). SNMP 3 requires many more options in form of encryption keys.
Your Provider or Administrator will be able to help with Community String.
Reference to OID used : http://oidref.com/1.3.6.1.4.1.11.2.3.9.4.2.1.1.3
Following are two options I’ve used with tool to identify Printer Details-
- Option 1- Name with OID, Custom OID option - Enter a custom OID to access a specific OID value on the device.
Select SNMP V1, provide Community String and OID to get Model Name of printer.
Input all information and click on Start, Section on right will display attributes.
Please refer the link about to find out OID and the attribute that it stand for.
- Option 2-MIB/OID walk through to retrieve all possible details- This option sends a SNMP request to get all OIDs starting with the OID part you enter here.
Please refer the link about to find out OID and the attribute that it stand for.
