ProLiant BL p-Class GbE Interconnect Switch Command Line Interface Reference Guide

Configuring the GbE Interconnect Switch using the Command Line Interface
The authentication protocol ensures that both the switch SNMP agent and the remote user
SNMP application program discard packets from unauthorized users. SNMP (version 1)
implements a form of security by requiring that each request include a “community string.” A
community string is an arbitrary string of characters used as a “password” to control access to
the GbE Interconnect Switch. If the GbE Interconnect Switch receives a request with a
community name it does not recognize, it triggers an authentication trap.
Traps are messages that alert you of events that occur on the GbE Interconnect Switch. The
events can be as serious as a reboot (someone accidentally reset the interconnect switch), or
less serious like a configuration file update. The GbE Interconnect Switch generates traps and
sends them to the network manager (trap recipient).
Trap recipients are special users of the network who are given certain rights and access in
overseeing the maintenance of the network. Trap recipients will receive traps sent from the
GbE Interconnect Switch, and they may take certain actions to avoid future failure or
breakdown of the network.
You can specify which network managers may receive traps from the interconnect switch by
entering a list of the IP addresses of authorized network managers. Up to four trap-recipient
IP addresses and four corresponding SNMP community strings can be entered.
In addition, the GbE Interconnect Switch supports Remote Management (RMON) version 1,
groups 1 (Statistics), 2 (History), 3 (Alarm), and 9 (Event).
The following shows the SNMP factory default settings:
Feature Default Value
SNMP Community String
• public
• private
SNMP Community String Access Right
• public = read-only
• private = read/write
SNMP Trap Manager IP None
Adding SNMP Management Interface Community Strings
SNMP allows up to four community names to be defined. The community names “public”
and “private” are defined by default. You can change the names in addition to adding others.
You must coordinate these names with the community name settings you use in your network
management system.
