Control Access to the Switch
Control Access to the Switch
Username-and-password pairs prevent unauthorized access by those who could
guess the password. We recommend that the switch has at least one
username-and-password pair to secure access to the device manager.
During initial setup, you can enter one username-and-password pair. You must
enter both a username and password.
After initial setup, you can add, modify, and delete username-and-password pairs
from the Users and Passwords window (
Figure 3-5 ).
Many users can have the same password. However, a username can only have one
password.
You can modify passwords but not usernames. If you no longer want a specific
username, you must first delete it, and then add the new username. Deleting a
password also deletes the username.
To display the Users and Passwords window, choose Configure > Users and
Passwords from the device manager menu. See the device manager online help
for additional guidelines and procedures.
PoE
Whether PoE will be supplied to a connected device. Choose either:
• Auto (automatically) to automatically provide power when an
IEEE 802.af-compliant or Cisco pre-standard device is connected.
• Never from the drop-down list.
The default is Auto.
Note
This setting is available only on PoE ports.
