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
Link Up or Link Down
Cold Start or Warm Start When the print server restarts, the cold start or warm start trap
Authentication Failure
In the print server's SNMP implementation, the following MIB objects are available for
updating.
MIB Object Names
system.sysContact
system.sysName
system.sysLocation
snmp.snmpEnableAuthenTraps
Description
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.
message is generated.
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
memory), an authentication failure trap message is generated.
Description
Indicates the network administrator's name.
Indicates the print server's name for identification.
Indicates the location of the print server.
