questions about SNMP.

[Lisa000]

Hi, I am doing a project in which a NMS tries to get information from multiple managed devices. I wonder if any guru can answer my questions:
1. Can NMS broadcast SNMP request to get information from all devices? Then how do the devices respond it? Or may be NMS need to use select() to get asynchrony information?
2. I want to get printer’s information such as brand, model(e.g. Laser), type(e.g. color, white-black), How to know the OID? Seems that it is defined by enterprise (e.g. I google and found 1.3.6.1.4.1.311.1.7.1.1 means inetSrvStats … of Microsoft. Is there official place to find OID?
3. what if the enterprise does not provide the MIB and OID?
4. If I want to get printer’s information,

Hmm, these look suspiciously like homework questions. Did you ever find the answers to these? If not, where have you looked?

hello,
if u wants to access any object from NMS compulsary u should have MIB file.
and u can find some mibs in mibsearch.com site. u can download it and save it to in ur system. and copy this mib into ur SNMPc managers mib directory where u installed ur manager. and compile the mib by selecting mibdatabase from config menu.
