Xerox 4500 PS TR

19. Problem Determination

This chapter describes how to monitor the operations of the Xerox 4500 PS TR and how to troubleshoot the supported protocols during installation, configuration, and printing.

19.1 Monitoring tools

The operations of the Xerox 4500 PS TR may be monitored using the SNMP (MIB II) or the LEDs on the rear panel.

19.1.1 SNMP support

The Xerox 4500 PS TR has been added support for SNMP using TCP/IP as protocol for LAN access. The SNMP operates as a monitoring tool for the Xerox 4500 PS TR .

19.1.1.1 What is SNMP

SNMP (Simple Network Management Protocol) is an application protocol offering network management services in the Internet Protocol suite to operate in connection with installation, configuration and management of the PS.

SNMP defines a client/server relationship. The client program is the connection to the SNMP agent (the PS) which is referred to as the SNMP Management Information Base (MIB). The SNMP implementation in the Xerox 4500 PS TR supports the MIB II.

There are, however, exceptions to the extension of MIB II support:

The SET option on different objects (ARP table, ROUTE table, etc.) will not be supported and any attempt to SET the objects will be rejected. No support for EGP and Transmission Group.

By default the application uses the community string “public” for SNMP GET and SET operations. If the community string used by NMS (Network Management System) does not match the one expected by the SNMP agent in the managed device, the operation fails.

NOTE:

You should be aware that a small amount of knowledge is required for general use the SNMP. It is assumed that you have basic networking knowledge (protocols, addressing, network errors, etc). For more advanced use of SNMP, you are required a substantial amount of knowledge.
