Password Protection

The DES-3010F/DES-3010FL/DES-3010G/DES-3016/DES-3018/DES-3026 switch does not have a default user name and password. One of the first tasks when setting up the Switch is to create user accounts. If you log in using a predefined administrator-level user name, you have privileged access to the Switch's management software.

After your initial login, define new passwords for both default user names to prevent unauthorized access to the Switch, and record the passwords for future reference.

To create an administrator-level account for the Switch, do the following:

•At the CLI login prompt, enter create account admin followed by the <user name> and press the Enter key.

•You will be asked to provide a password. Type the <password> used for the administrator account being created and press the Enter key.

•You will be prompted to enter the same password again to verify it. Type the same password and press the Enter key.

•Successful creation of the new administrator account will be verified by a Success message.

NOTE: Passwords are case sensitive. User names and passwords can be up to 15 characters in length.

The sample below illustrates a successful creation of a new administrator-level account on the DES-3026 with the user name "newmanager". The commands for creating a new administrator-level account are identical for the DES-3010F, DES-3010FL, DES-3010G, DES-3016 and DES-3018 switch models.

DES-3026:4#create account admin newmanager

Command: create account admin newmanager

Enter a case-sensitive new password; *****

Enter the new password again for confirmation: *****

Success

DES-3026:4#

NOTICE: CLI configuration commands only modify the running configuration file and are not saved when the Switch is rebooted. To save all your configuration changes in nonvolatile storage, you must use the save command to copy the running configuration file to the startup configuration.

SNMP Settings

Simple Network Management Protocol (SNMP) is an 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.
