Saving Configuration Changes; Snmp Settings - D-Link DGS-6600 Series Hardware Installation Manual

DGS-6600 Layer 3 Chassis Ethernet Managed Switch Hardware Installation Guide
When creating a user account, the user can specify if the password will be entered in an encrypted or plain text
form. If a password is entered into the Switch in plain-text form, but the password encryption function is enabled;
the password will be converted to encrypted form.
NOTICE: Make sure that the password is changed correctly before saving the changes to
the startup configuration
To create a new user account, use the following command in global configuration mode:
DGS-6600:15(config)#username admin privilege 15 password plain-text mypassword
DGS-6600:15(config)#
The command creates a user with the administrator level 15 (Privileged EXEX) and account username admin .
The password is mypassword which is not encrypted. To save configuration changes refer to the following:
Saving Configuration Changes on page 63.

Saving Configuration Changes

When making changes to the DGS-6604 configuration you must copy the current configuration (running-config)
to the Start-up configuration (startup-configuration). If this configuration copy is not performed the next bootup of
the switch will not initialize with the changes made and they will be lost. Use this command after making changes
you want to save:
DGS-6600:15#copy running-config startup-config
Save system configuration (y/n) [n]?Y
Configuration has been copied successfully.
DGS-6600:15#

SNMP Settings

Simple Network Management Protocol (SNMP) is an Open Systems Interconnection (OSI) Layer 7 (Application
Layer) designed specifically for managing and monitoring network devices. SNMP enables network management
stations to read and modify the settings of gateways, routers, switches and other network devices. Use SNMP to
configure system features for proper operation, monitor performance and detect potential problems in the Switch,
switch group or network.
Managed devices that support SNMP include software (referred to as an agent), which runs locally on the device.
A defined set of variables (managed objects) is maintained by the SNMP agent and used to manage the device.
These objects are defined in a Management Information Base (MIB), which provides a standard presentation of
the information controlled by the on-board SNMP agent. SNMP defines both the format of the MIB specifications
and the protocol used to access this information over the network.
The Switch supports SNMP versions 1, 2c, and 3. The administrator may specify which version of SNMP to use
to monitor and control the Switch. The three versions of SNMP vary in the level of security provided between the
management station and the network device.
In SNMP v.1 and v.2, user authentication is accomplished using 'community strings', which function like
passwords. The remote user SNMP application and the Switch SNMP must use the same community string.
SNMP packets from any station that has not been authenticated are ignored (dropped).
The default community strings for the Switch used for SNMP v.1 and v.2 management access are:
"public - Allows authorized management stations to retrieve MIB objects.
"private - Allows authorized management stations to retrieve and modify MIB objects.
