IP Source Guard
IP Source Guard is a secure feature used to restrict IP traffic on DHCP snooping untrusted ports by filtering traffic based on
the DHCP Snooping Table or manually configured IP Source Bindings. It helps prevent IP spoofing attacks when a host
tries to spoof and use the IP address of another host.

rotocol(LLDP) specified in this standard allows stations attached to an IEEE 802 LAN to
advertise, to other stations attached to the same IEEE 802 LAN, the major capabilities provided by the system
incorporating that station, the management address or addresses of the entity or entities that provide management of those
capabilities, and the identification of the stations point of attachment to the IEEE 802 LAN required by those management
entity or entities. The information distributed via this protocol is stored by its recipients in a standard Management
Information Base (MIB), making it possible for the information to be accessed by a Network Management System (NMS)
using a management protocol such as the Simple Network Management Protocol (SNMP).

MAC Table
Switching of frames is based upon the DMAC address contained in the frame. The switch builds up a table that maps MAC
addresses to switch ports for knowing which ports the frames should go to ( based upon the DMAC address in the frame ).
This table contains both static and dynamic entries. The static entries are configured by the network administrator if the
