SNMP Commands
A manager requests information from an agent by sending a single command, the
Get command. The Get command also has a variation (GetNextRequest)
that permits more efficient operation:
■ GetRequest – Requests the value of a specified variable on the agent. This
command is used to retrieve management data.
■ GetNextRequest – Requests the value of the next variable after the one
specified in the command. This command is used to retrieve lists and tables of
management data.
An agent responds to a request by sending a single command, the GetResponse
command. This command contains the requested information.
A manager changes information (variables) in the agent by sending a single
command, the SetRequest command. This command is used to manipulate
management data.
A trap is used by an agent to report extraordinary events. Refer to “Traps and
Their Purpose” on page 20.
