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.
