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:
1. At the CLI login prompt, enter create account admin followed by the <user
name> and press the Enter key.
2. You will be asked to provide a password. Type the <password> used for the
administrator account being created and press the Enter key.
3. You will be prompted to enter the same password again to verify it. Type the
same password and press the Enter key.
4. Successful creation of the new administrator account will be verified by a
Success message.
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.

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
NOTE: Passwords
are case sensitive.
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.
