SNMP Parameter Configuration


SNMP Community Pool
An SNMP "Community"is a relationship between an SNMP agent and a set of SNMP managers that defines authentication, access-control, and proxy characteristics. Its mechnism is that by showing it to the SNMP agent, a user who wish to use the SNMP device can identify himself/herself, and that allows the SNMP agent to decide what sort of "Access Right" to give to the user. There are three kinds of access rights: "DENY, READ-ONLY, READ-WRITE". The accessing community with "DENY" configured here would be denied of its access. "READ-ONLY" allows the user to read but is not allowed to alter any of the SNMP settings. "READ-WRITE" allows both read and write abilities. The "Valid" field is used to enable/disable its corresponding row. When disabled, such community with no matter what access right is defined for it, would be denied of its entry. This field is usually used when you just want to temporarily diable the entry for a party and do not wish to erase this settings.

 

SNMP Trap Host Pool
Usually the SNMP agent responds when a request/command is made from a manager station. But for a trap operation, it is the reverse of such a case - the agent automatically sends an unsolicited (not requested by the manager) respond back to the manager simply if a certain predefined condition has been met. "Community" and "IP Address" refer to which community and IP address these unsolicited repsonds should be sent to. What type of SNMP version a respond belongs to can be defined in the field "Version". The option "Free" refers to that a respond may belong to version 1 or version 2.
