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 system.sysContact system.sysName system.sysLocation Description Indicates the network administrator's name. Indicates the print server's name for identification. Indicates the location of the print server. snmp.snmpEnableAuthenTraps 45

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.
