Denial of Service (DoS)
Security > Denial of Service
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
on page 7).
2. Click on Security and click on Denial of Service.
