Topics to Look For¶
- Ethernet learning algorithm
- MAC flooding
- Distributed spanning tree algorithm
Reading¶
- Dordal: 2.4 - Ethernet Switches
-
MAC flooding
— describes an attack on switches to allow packet capture (“sniffing”) where a switch would normally prevent it. - Dordal: 3.0-3.1 - Spanning Tree Algorithm and Redundancy
Supplemental¶
- Peterson & Davie, 6th ed: 3.2 [note: this may gloss over some parts of the distributed spanning tree protocol so much that it may not make sense if you really try to follow it]
- CNP3: Ethernet Switches and CNP3: The Spanning Tree Protocol (802.1d) — This is complementary to the assigned Dordal reading above. Use it to augment any confusing parts from Dordal or to add detail if you’re interested.
