4.3 Ethernet Access: Telnet and SNMP Protocols

The optional 10/100 BaseT Ethernet port provides Telnet- or SNMP-based monitoring and management.

The 10/100 Base T Ethernet management services
card provides Telnet-based monitoring and
management, including firmware update using
FTP.

Remote system monitoring is also available using
Simple Network Management Protocol (SNMP).
An agent resides in the Diamond-VT which takes
information from the Array and translates it into a
form compatible with SNMP. If certain conditions
arise, the agent sends asynchronous notifications
(traps) to a client.

To connect to the Ethernet port

1

Connect a cross-over cable (for a direct
connection to a PC) or regular network cable
from a network device to the optional RJ45
Ethernet port on the Ethernet management
card on the front of the Diamond-VT.

2

If using a direct connection, power on and boot
up the host computer.

3

Attach a DB-9 null modem serial cable (the
cable must be no longer than three meters)
from the RS-232 port of the Diamond Array to a
host computer and open a terminal emulator
program on the host to set the Ethernet
parameters.Turn on the Diamond-VT.

4

First time use: Upon successful power up and
diagnostics, set the host computer with the
appropriate settings.

The host computer must have appropriate
network settings to allow it to communicate with
the Diamond-VT. Please see your system
administrator for more information.

To use Telnet

1

If you have not already done so, change the IP
address from the default by first accessing the
serial connection and using the CLI.

You may change the IP address to a network
specific value or, if the local network uses
DHCP, you may enable automatic IP
addressing (set IPDHCP enabled) using the
CLI.

2

Open a Telnet session on the host computer.

• IP

address

• Port type: telnet

• Terminal

type:

vt100

3

If you make any changes to the network setting
on the Diamond Array, use the
SaveConfiguration Restart

command.

4

Username/password: You are prompted for a
username and password, up to eight characters
each, case insensitive. Only one
username/password combination is available
per Diamond-VT.

• You may change the telnet username and/or

password after entering a CLI session using
the commands

set TelnetUsername [username]

set TelnetPassword [password]

• Or you may change the telnet username

and/or password using the Configuration
page of the ExpressNAV interface.

• The default username is telnet and default

password is diamond

.

5

In the Command Line Interface mode, see a list
of available commands by typing help at the
Ready prompt or refer to

Summary of CLI

Commands

on page 29.

6

Using the ExpressNAV interface, configure the
unit as RAID Level 10 or RAID Level 5 with
zones and/or Hot Spare sleds as described
later in the manual.

To use SNMP

1

Enter the Command Line Interface through the
serial port or Ethernet.

2

Change the IP address to a network specific
value or, if the local network uses DHCP,
enable automatic IP addressing.

3

Set the number of trap client addresses by
typing set SNMPTrapAddress [1-6]
[IPAddress] [Level]

4

Type set SNMPUpdates enabled.

5

Type set SNMPTraps enabled.

6

Type SaveConfiguration restart to reboot the
Diamond-VT.

7

Install SNMP management software on each
client you wish to receive traps (messages).
