DES-3550 Fast Ethernet Layer 2 Switch
Password Protection
The DES-3550 does not have a default user name and password. One of the first tasks when settings 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 with the user name "newmanager".
DES-3550:4#create account admin newmanager
Command: create account admin newmanager
Enter a case-sensitive new password:********
Enter the new password again for confirmation:********
Success.
DES-3550:4#
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
