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?

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. :-) Regards, Joel Hansell On Thu, Apr 10, 2014 at 4:25 PM, < [email protected] > wrote:question about SNMP Protocol: where is installed MIB files (vendor-specific): on the Network management station (NMS) or on the network devices (network node)? ------------------------------------------------------------------------------ Put Bad Developers to Shame Dominate Development with Jenkins Continuous Integration Continuously Automate Build, Test & Deployment Start a new project now.
