5 Configuration D-Link Web Smart Switch User Manual
The ARP Spoofing Prevention function can discard the ARP Spoofing Attack in the network by checking the
gratuitous ARP packets and filtering those with illegal IP or MAC addresses. Enter the Router/Gateway IP
Address, MAC Address, Ports and then click Add to create a checking/filtering rule. Click Delete to remove
an existing rule and Delete All to clear all the entries.
Figure 93 – Security > ARP Spoofing Prevention Setting
Security > Port Security
Port Security is a security feature that prevents unauthorized computers (with source MAC addresses)
unknown to the Switch prior to stopping auto-learning processing from gaining access to the network.
A given ports’ (or a range of ports') dynamic MAC address learning can be stopped such that the current
source MAC addresses entered into the MAC address forwarding table can not be changed once the port
lock is enabled. Using the drop-down menu, change Admin State to Enabled, and then click Apply to
confirm the setting.
Figure 94 – Security > Port Security
Security > SSL Settings
Secure Sockets Layer (SSL) is a security feature that provides a secure communication path between a Web
Management host and the Switch Web UI by using authentication, digital signatures and encryption. These
security functions are implemented by Ciphersuite, a security string that determines the cryptographic
parameters, encryption algorithms and key sizes.
This page allows you to configure the SSL global state and the Ciphersuite settings. Select Enable or
Disable and then click Apply to change the SSL state or the Ciphersuite settings of the Switch. By default,
SSL is Disabled and all Ciphersuites are Enabled.
