b. Type 1 to select IP Address and, when prompted, enter the IP
address of one of the devices connected to the switch, preferably
the lowest IP address.
c. Type 2 to select Subnet Mask and enter the mask. A binary “1”
indicates the switch should filter on the corresponding bit of the
IP address, while a “0” indicates that it should not. As an example,
assume that the devices connected to a switch are using the IP
address range 149.11.11.1 to 149.11.11.50. The mask would be
0.0.0.63.
d. If you are activating the Land defense, type 3 to select Uplink Port
and enter the number of the port connected to the device (e.g.,
DSL router) that leads outside your network. You can specify only
one uplink port.
e. Type R to return to the Denial of Service (DoS) Configuration
menu and continue with the next step.
4. Type the number of the DoS attack that you want to enable or disable.
5. When prompted, enter the port(s) where you want to enable or
disable a defense mechanism.
Note
If you plan to use the Teardrop defense, Allied Telesyn recommends
activating it on only the uplink port and one other port. The defense
is CPU intensive and can overwhelm the switch’s CPU.
