Denial of Service
Denial of Service (DoS)
Security > DoS
The switch has built-in DoS prevention features to restrict specific type of traffic
associated denial of service attacks on your network. By default, all of the DoS settings
are set to Allow, which allow any type of traffic to pass through the switch. Setting one
of the items to Deny will set the switch to check for traffic matching the selected item
and deny any traffic matching the rule. On the other hand, setting one of rules to Deny
may deny a specific type of traffic that may prevent traffic essential to running your
network such as devices in load balancing configuration using virtual IP addresses (Ex. If
ARP MAC SA Mismatch is set to Deny, it may cause devices in load balance configuration
using shared virtual IP addresses communication issues essential for network server
load balancing.) For additional security, you can set these rules to Deny as necessary.
1. Log into your switch management page (see
"Access your switch management
page"
on page 9).
2. Click on Security and click on DoS
3. Select Enabled to enable DoS or Disabled to disable DoS.
4. Click Apply to save the settings to the Flash.
Note: This step saves all configuration changes to the NV-RAM to ensure that if the
switch is rebooted or power cycled, the configuration changes will still be applied.
