About switching, vlans and spanning tree notes
GoConqr OriginalSwitching, VLANs and Spanning Tree notes
The notes approach this unit through individual protocols and switch features. Spanning Tree introduces redundant Ethernet links and switching loops, while VTP and DTP cover VLAN replication and trunk negotiation. The EtherChannel Tutorial discusses protocols used to create EtherChannels.
Working with the notes
The note on CCNP switch basics is a useful starting point for looking at MAC address table commands. From there, Spanning Tree provides context for the shorter STP and RSTP notes. The notes on port channels and EtherChannel offer another route through link aggregation.
As you read, summarize each protocol's purpose and compare the commands or modes described. Return to the notes when you need to check a detail. When you want to test your recall, switch to a quiz on the unit page; a mind map can help you organize related topics. Choose a note and begin with the topic you need most.
Frequently asked questions
Which note is a useful starting point?
The note on CCNP switch basics is a useful place to start if you want to look at MAC address table commands. For spanning tree, Spanning Tree introduces redundant links and switching loops before you move on to the more focused STP and RSTP notes.
What topics do these notes cover?
The notes cover spanning tree, VLAN replication, trunk negotiation and EtherChannel. VTP discusses VLAN replication, while DTP looks at negotiated trunking. EtherChannel Tutorial describes protocols for creating EtherChannels, and the port channel note lists PAgP and LACP modes.
Are these notes free to use?
Yes. Every note listed here is free to open and study without an account. The resources were made by GoConqr users. A free account also lets you save quiz scores and make your own quizzes, mind maps, flashcards and notes.
