Troubleshooting Spanning Tree Protocol

I have made configurations on the three switches:

commands @ S$1$:

S$1($config$)$#spanning$-$tree vlan $10$ priority $4096$

S$1($config$)$#spanning$-$tree vlan $20$ priority $16384$

commands @ S$2$:

S$2($config$)$#spanning$-$tree vlan $20$ priority $4096$

S$2($config$)$#spanning$-$tree vlan $30$ priority $16384$

commands @ @S$3$:

S$3($config$)$#spanning$-$tree vlan $30$ priority $4096$

S$3($config$)$#spanning$-$tree vlan $10$ priority $16384$

But, completion meter is still stuck at $0\%.$ CPEP$114$L: Troubleshooting Spanning Tree Protocol

Learning Objectives

Identify the initial state of all trunks.

Correct the source of the problem.

Document the switch configuration.

Scenario

forwarding packets in the default STP configuration currently running. The solution to this problem requires more effective use of the available trunks.

This activity is complete when all wired trunks are carrying traffic, and all three switches are participa
