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

1Connect 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.

2If using a direct connection, power on and boot up the host computer.

3Attach 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.

4First 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

1If 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.

2Open a Telnet session on the host computer.

•IP address

•Port type: telnet

•Terminal type: vt100

3If you make any changes to the network setting on the Diamond Array, use the SaveConfiguration Restart command.

4Username/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.

5In 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.

6Using 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

1Enter the Command Line Interface through the serial port or Ethernet.

2Change the IP address to a network specific value or, if the local network uses DHCP, enable automatic IP addressing.

3Set the number of trap client addresses by typing set SNMPTrapAddress [1-6] [IPAddress] [Level]

4Type set SNMPUpdates enabled.

5Type set SNMPTraps enabled.

6Type SaveConfiguration restart to reboot the Diamond-VT.

7Install SNMP management software on each client you wish to receive traps (messages).
