Parameters

callback

A RequestReceived delegate specifying the method to execute when a RequestMessage is received.

localEP

IPEndPoint specifying the local network interface to bind to.

acceptBroadcast

Specifies whether the Agent should accept requests that are broadcast to the network. Must be false when using an IPv4-mapped IPv6 dual mode socket.

dualMode

Specifies whether the socket should be a dual mode IPv6 socket. Only supported on Vista and newer operating systems.

state

Object to pass to the callback method; can be null.

Use this method to receive SNMP requests from SNMP managers. It is possible for the RequestReceived delegate to be raised concurrently on multiple IO Completion threads, so its code should be thread-safe.

If dual mode (simultaneous IPv4 and IPv6) socket operation is desired, use IPAddress.IPv6Any (for all IPv4 and IPv6 interfaces) or an IPv4-mapped IPv6 address for the localEP address, and true for the dualMode argument. An IPv4-mapped IPv6 address is the IPv4 address of a network interface preceded by "::ffff:". Ex: ::ffff:192.168.1.1. If an IPv4-mapped IPv6 address is used then acceptBroadcast must be false. To accept broadcast packets in dual mode, IPAddress.IPv6Any must be used.

This method always creates a new SocketBase.Socket. Use multiple Agent instances to accept SNMP requests on multiple sockets.

Unhandled exceptions thrown on the IO Completion thread are caught and reported by the Error event.

Scripting applications should use Receive instead.
