The First One
A logical grouping of computers through segmentation in a LAN.
What is a Virtual local area network (VLAN)?
The process of providing electrical power to a device by means of a copper Ethernet cable.
What is Power over Ethernet (PoE)?
A switch feature that restricts connection to a given port based on the MAC address.
What is MAC filtering/port security?
An attack in which the attacking host adds two VLAN tags instead of one to the header of the frames that it transmits.
What is Double Tagging?
This comic about a blockheaded kid and his dog is one of the most famous strips of all time. It also spawned one of the most watched Christmas special of all time?
What is Peanuts?
A port configuration that allows multiple VLANs to connect through a single port and is also known as a tagged port.
What is a Trunk Port?
Ethernet frames that exceed the IEEE 802.3 limit of a 1,500 byte payload and can carry a payload of up to 9,000 bytes.
What are Jumbo Frames?
A table maintained by a switch that contains MAC addresses and their corresponding port locations.
What is a Content Addressable Memory (CAM) table?
An unsecure protocol that could allow unauthorized devices to modify a switch's configuration.
What is Dynamic Trunking Protocol (DTP)?
This cartoon cat hates Mondays and enjoys kicking dogs off of tables.
What is Garfield?
A port that allows traffic from only one VLAN.
What is an Access Port?
A switch port security feature that adds the MAC addresses of known devices to the Content Addressable Memory (CAM) table, or MAC address table. These MAC addresses can be dynamically learned or entered manually.
What is Sticky MAC?
An attack that overloads a switch's MAC forwarding table to make the switch function like a hub.
What is MAC Flooding?
A routing technique in which every router sends information about directly connected links to all the routers in the network.
This kid and tiger duo ponders life, philosophy, and the art of slacking off on homework.
What is Calvin and Hobbes?
A buffer network (or subnet) that sits between the private network and an untrusted network (such as the internet.) Also known as an all-in-one appliance.
What is a Screened Subnet?
An attack in which the attacker's MAC address is associated with the IP address of the target's device.
What is ARP Spoofing?
A routing protocol that does not have subnet mask information in the routing updates.
What is Classful Routing Protocol?
A routing technique in which every router sends a complete topography of the routers in the network out to directly connected routers.
What is Distance Vector Routing?
This comic strip is about cavemen and prehistoric animals that make puns and other gags.
What is B.C.?
A line sensing port configured to automatically detect the needed cable connection type and then configure the connection accordingly.
What is Automatic-medium dependent interface crossover (auto-MDIX)?
To avoid switching loops, switches use these frames to determine the network topology. These frames contain such things as the switch ID, its MAC address, and switch port cost. This is an important function used by Spanning Tree Protocol (STP), which is used to prevent these switching loops.
What is a Bridge Protocol Data Unit (BPDU)?
A routing protocol that does include subnet mask information in the routing updates.
What is Classless Routing Protocol?
Firewalls use filtering rules, which are sometimes called this, to identify allowed and blocked traffic.
What is an Access Control List (ACL)?
This comic strip about an orange cat is often mistaken as a ripoff of the more popular Garfield, but it actually came first.
What is Heathcliff?
