Silex technology SX-560 manual Configuring Snmp, Snmp Commands, Command Description

Configuring SNMP

The SX-560 module contains a Simple Network Management Protocol (SNMP) agent that collects and stores management information for network managers using standard SNMP commands. The management information is referenced as a hierarchically organized database called a Management Information Base (MIB).

To prevent naming conflicts, all of the manageable features of all products from all vendors are arranged in a single tree structure. Each vendor of SNMP equipment has an exclusive section of the MIB Tree.

Each branch of the MIB Tree has a number and name. The path from the top of the tree down to the point of interest forms the name of that point. A name created in this way is known as an Object ID or OID.

Table 20 describes the messages used to communicate between the network manager and the SNMP agent, as defined in RFC 1157. Each SNMP message must contain a Community Name, which is used like a password. The default Community name for the SX-560 module is PUBLIC.

	Table 20 SNMP Commands
Command	Description
GET	Retrieves management information for a specific managed object contained in the
	agent.
	The GET message must contain the OID for the specified object. The response is a
	GET-RESPONSE message containing either the current value of the requested
	object, or an indication as to why the request failed.
GET NEXT	Retrieves management information from a non-specific managed object.
	The GET NEXT contains either a complete OID or a fragment of an OID. The
	response is a GET-RESPONSE message containing either the OID and data of the
	item immediately right of the specified OID in the tree or an indication as to why the
	request failed.
GET	This is the information sent back from the unit in response to the GET, GET NEXT
RESPONSE	command.
SET	Requests a change to the value of a specified object.
	The response is a GET-RESPONSE message with either an indication that the
	requested change had been made or with an indication as to why the request failed.
TRAP	Sends a one-way notification from the agent to the manager that a significant event
	has occurred. This is the only message initiated by the SNMP agent.

To configure the SNMP server settings:

1.Log into the SX-560 internal web pages using a standard web browser. Click Server Settings to access the screen shown in Figure 10. You can then enter the relevant SNMP information for your network.
