SNMP代理如何将正确的数据映射到相应的对象标识符

Question

For example, sending a GET request to receive how many hours a device has been on for. You send the OID value with the GET request from the manager to an agent, so the agent knows which MIB to traverse into etc... But once it has checked and validated the OID exists how does the correct data get mapped to that specific OID in order to send it back?

Thanks.

Answer 1

It is very specific to SNMP agent implementation. SNMP does not cover this part. It is up to you as SNMP agent developer to decide how you bind OIDs and values.

Usually, it is some sort of hash table that maps oid to value.
