3.3.4 - Spanning Tree Protocol Configuration

Flashcards about Spanning Tree Protocol Configuration

What is the purpose of setting the priority value in spanning tree configuration?

To predetermine root bridge selection.

Why should the root bridge be part of a high-bandwidth backbone or core switch group?

Performance will suffer if a switch on a low-bandwidth segment becomes root.

What command is used to report the current spanning tree configuration on a Cisco switch?

show spanning-tree

Which frames does the port drop in the Blocking state?

All frames other than BPDUs.

In which port state does the port listen for BPDUs to detect loops?

Listening

In which port state does the port discover the topology of the network and build the MAC address table?

Learning

What two states are ports typically in when the network is converged?

Forwarding or Blocking

What happens when the network is not converged?

No communications can take place.

What is the key difference between 802.1D and RSTP regarding network availability during configuration changes?

RSTP creates outages of a few seconds or less, while 802.1D can cause extended periods of unavailability (tens of seconds).

In RSTP, what happens to the blocking, listening, and disabled states?

They are aggregated into a discarding state.
