SNMP Setup
TCP/IP networks use a standard management protocol called Simple Network
Management Protocol (SNMP). SNMP is widely used in the industry as a solution for
remote network management and monitoring of networking devices. SNMP actually
includes a protocol, a database structure specification, and a set of database objects. The
database objects are contained in a standard database called Management Information
Base (MIB) that is stored on the networking device called SNMP agent. The print server's
SNMP implementation runs in a TCP/IP environment.
A host on the network running Network Management System (NMS) software can access
the print server device by reading and writing the MIB objects stored in the device. The
Network Management Systems are available from many third-party vendors, such as
Hewlett-Packard's OpenView.
When accessing (traversing) MIB objects in the print server using NMS software called
SNMP manager, you need to provide a community name in each SNMP request for
authentication purpose. The print server supports up to two community names. The default
community name is public (case-sensitive), with Read Only access right in default.
When an unusual condition or activity occurs, the SNMP agent alerts the SNMP manager
through SNMP traps. Following list summaries SNMP trap messages that the print server
will send out.
Activities/SNMP Trap Messages Description
Link Up or Link Down When the network interface on the print server fails, a
link down trap message is generated; if the network
interface comes back to life, a link up trap message is
sent.
Cold Start or Warm Start When the print server restarts, the cold start or warm
start trap message is generated.
Authentication Failure When the print server received a SNMP request with
a community name that does not match the
community name the print server is configured with
(stored in the print server's memory), an
authentication failure trap message is generated.
In the print server's SNMP implementation, the following MIB objects are available for
updating.
MIB Object Names Description
system.sysContact Indicates the network administrator's name.
system.sysName Indicates the print server's name for identification.
system.sysLocation Indicates the location of the print server.
