Hi,
Thank you for input.
I don't understand. I've read specification RFC 2741 and RFC 1157, not full
though, just important moments. My understanding is that SNMP is protocol, SNMP
agent is plain daemon that run on the background, and MIB files is a sort of
centralized database, where agent sends a request. Therefore MIB database must
be installed somewhere. If MIB files is not installed, where SNMP agent will
take information about OID values?
Well, suppose it depends on application and network device. Where the MIB files
resides on cable modem or set-top box, for example? Is it hard-coded into their
program code or they are located on a management station? If its hard-coded
inside program code, then to add a new MIB file requires replacement of the
entire software, if its on management station, then we just need add new MIB to
database which is more easy?
Thanks

Dear Anonymous,
In principle, the MIB files don't have to be installed anywhere. They are only
a specification. The describe which objects are available on the agent, and
which notifications the agent may send.
Some SNMP managers let the user "load" MIB files, in order to better present
the data fetched from the agents. But this is not mandatory.
Some SNMP agents let the user "load" MIB files, to alter structure of the data
which is published, but this is more unusual. Many SNMP agents in industrial
use have the MIB structure hard-coded into their program code.
I'm sure such an answer will lead to more questions, please go ahead. :-)

Joel Hansell
