Configure Simple Network Management Protocol
The SX-550 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 23 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-550 module is PUBLIC.
Table 23 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
RESPONSE This is the information sent back from the unit in response to the GET, GET NEXT
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 set the SNMP Traps:
1. Using ExtendView, web browser interface or internal command console, click SNMP Traps tab. The
SNMP Traps window displays.
