Security > Gratuitous ARP
The Gratuitous ARP page shows the settings on the Switch. An ARP announcement (also known as
Gratuitous ARP) is a packet (usually an ARP Request) containing a valid SHA (Sender Hardware Address)
and SPA (Sender Protocol Address) for the host which sent it, with TPA (Target Protocol Address) equal to
SPA. Such a request is not intended to solicit a reply, but merely update the ARP caches of other hosts
which receive the packet and determine if there are any IP conflicts.
Figure 4.115 – Security > Gratuitous ARP
Send when IP Interface is up: This is used to enable/disable the sending of gratuitous ARP request
packets while an IP interface comes up. This is used to automatically announce the interface’s IP address to
other nodes. By default, the state is Disabled, and only one ARP packet will be broadcast.
Send when duplicated IP is detected: This is used to enable/disable the sending of gratuitous ARP
request packets while a duplicate IP is detected. By default, the state is Disabled. Duplicate IP detected
means that the system received an ARP request packet that is sent by an IP address that matches the
system’s own IP address.
Learn received Gratuitous ARP: This is used to enable/disable updating ARP cache based on the received
gratuitous ARP packet. If a switch receives a gratuitous ARP packet and the sender’s IP address in its ARP
table, it should update the ARP entry. This is Disabled by default.
Gratuitous ARP Send Interval: Specify the interval value.
Interface Name: Specify the Interface Name.
Time Interval (0-65535): Specify the time interval, the range is from 0 to 65535, and the default is 0 seconds.

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 cannot be changed once the port is
enabled.
