What are the different steps in spanning tree operation? |
Determine root bridge Select root port Select designated ports Block ports with loops |
There are four steps. |
|
Define backbonefast |
PVST enhancement which enables immediate expiration of max-age timer in the event of an indirect link failure. |
Deprecated by Rapid-PVST alternate port state. (?) |
|
Define portfast |
Forces switchport to immediately transition to "forwarding" state (Designates port as "edge" in MST) |
|
|
What is the default Forward Delay timer length? |
15 seconds |
|
|
Define a RSTP Shared link. |
Potentially connects to multiple bridges (half-duplex) |
|
|
What is the default Max-age timer length? |
20 seconds |
|
|
How does spanning tree pick a root port? (Spanning tree path selection) |
Bridge with lowest root ID becomes root Prefer neighbor with lowest cost to root Prefer neighbor with lowest bridge ID Prefer lowest sender port ID |
|
|
Define uplinkfast |
PVST+ enhancement which enables switches to maintain backup paths to root bridge. |
Deprecated by Rapid-PVST backup port role.(?) |
|
If I want a switch to become the root, do I want high or low priority? |
Low |
Golfing is fun |
|
Define BPDU Guard |
Err disables a port if a BPDU is received. |
|
|
Define Loop Guard |
Prevents a blocked port from transitioning to listening state after max age timer has expired |
|
|
Define a RSTP Point-to-Point (P2P) link. |
Connects to exactly one other bridge. (Full Duplex) |
|
|
What is the default hello timer length for 802.1d? |
2 seconds |
|
|
Define Root Guard |
Prevents a port from becoming the root port. |
|
|
Define Loop inconsistency |
When a loop guard enabled port stops receiving BPDUs, it moves to a loop-inconsistent state. |
Loop guard |
|
When using the command "show spanning tree, what does the output "P2P Bound" mean? |
Connected device is outside of the MST region |
|
|
Define Root inconsistency |
A root inconsistency comes from a port trying to advertise a better root bridge than the current root bridge. |
