Manage automatic denial of service
Automatic denial of service prevention mode (Auto DoS prevention mode) enables all
the DoS features. By default, Auto DoS prevention mode is enabled but you can disable
it. We recommend that you keep the Auto DoS prevention mode enabled.
The TCP and UDP ports are always enabled, but you can shut down individual ports
(see Manage the port speed and the port status on page 60).
To manage the Auto DoS prevention mode:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired network connection, or connect directly to a switch that
is off-network using an Ethernet cable.
2. Launch a web browser.

In the address field of your web browser, enter the IP address of the switch.
If you do not know the IP address of the switch, see Access the switch using a web
browser on page 7.
