STB NIP 2212 Web Server

SNMP Protocol

Protocol Data Units (PDUs) within SNMP carry requests and responses between the

Data Units

manager and the STB NIP 2212 agent. The following PDUs are used:

(PDUs)

GetRequest—An SNMP manager uses the "Get" PDU to read the value of one

 

or more management information base (MIB) (See Management Information

 

￿Base (MIB), p. 107) objects from the STB NIP 2212 agent.

 

SetRequest—An SNMP manager uses the "Set" PDU to write a value to one or

 

more objects resident on the STB NIP 2212 agent.

 

These PDUs are used in conjunction with MIB objects to get and set information

 

contained in an Object Identifier (OID).

The STB NIP 2212 is configured with SNMP, Version 1.0. When setting up the

Community

SNMP agent function for your STB NIP 2212 (See Configure SNMP Web Page,

Identifiers

p. 105), you should configure private community name(s) for GetRequest and

 

SetRequest.

 

 

 

Note: If you do not configure private community names for GetRequest and

 

SetRequest, any SNMP manager can read the MIB objects for your STB NIP 2212.

 

 

 

The community name is an identifier that you assign to your SNMP network when

 

you set up the SNMP manager. Community names for the SNMP manager and

 

agent must agree before SNMP processing can occur.
