SNMP Management

Introduction

SNMP management and iConfig are always through the Uplink port of the Prisma

EtherLinX unit. This provides a higher level of security because end-users cannot

access management, alter settings, etc.

Assigning IP Information

In order for the Prisma EtherLinX unit to allow for SNMP management, the unit

must be assigned IP configuration information (e.g., IP address, subnet mask, etc.)

using iConfig via PrismaView software; the unit's serial port or DHCP (Dynamic

Host Control Protocol). In addition to assigning an IP address and subnet mask, the

former two methods also allows you to create community strings, assign access

rights, configure traps, and more. However, iConfig offers more options than serial

port configuration (e.g., you can select which traps to assign with iConfig). After

assigning the Prisma EtherLinX unit an IP address, you can use PrismaView

software or another SNMP-compatible Network Management System (NMS) to

remotely configure, monitor, and manage the Prisma EtherLinX unit.

About Serial Port Configuration

Although the Prisma EtherLinX unit does not include a DB-9 serial port, you can use

the supplied RJ-45 to DB-9 adapter on Downlink Port 4 on the Prisma EtherLinX

unit. This adapter uses an IBM-compatible DB-9 serial connector.

Note: Use a straight-through (pin-to-pin) cable. If your computer/terminal has a

COM port using a connection not compatible with a DB-9 connector, use the pin

connection chart below for reference in making a cable.) Make sure the cable length

is less than 50 ft. (15.24 m).
