JNCIS-ENT Spanning Tree Practice Question
An administrator has deployed a new EX Series switch running RSTP and notices that access ports connected to end-user workstations take up to 30 seconds to transition to the forwarding state. Which configuration command should be applied to immediately resolve this delay for access ports?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
set protocols rstp interface ge-0/0/1.0 edge
In RSTP, edge ports transition directly to the forwarding state, bypassing the discarding and learning states. Configuring 'no-root-port' or designating the port as an edge port using 'set protocols rstp interface <interface> edge' allows workstations to connect without experiencing STP convergence delay.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
set protocols rstp interface ge-0/0/1.0 edge
Why this is correct
Designating the interface as an edge port skips the listening and learning states, immediately placing it into the forwarding state.
- ✗
set protocols rstp force-version stp
Why it's wrong here
Forcing the version to legacy STP would actually increase convergence times rather than decrease them.
- ✗
set protocols rstp interface ge-0/0/1.0 mode point-to-point
Why it's wrong here
Point-to-point status is automatically detected for full-duplex links and does not eliminate the initial forwarding delay unless edge is also configured.
- ✗
set protocols rstp bridge-priority 0
Why it's wrong here
Lowering the bridge priority affects root bridge selection, not edge port behavior.
