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).
