PA-3410 Spanning tree cannot be generated

L3 Networker

Hello all,

We have a PA-3050 configured with V-wire and are operating as STP Block on the uplink of Backbone_B.
 
We are going to replace PA-3050 with new construction equipment, PA-3410.
 
STP blocks are not generated in the in-house LAB before deployment, and disconnect occurs during communication.

In conclusion, the issue has been resolved.



1. Set the section between ISP <-> PA-3410 <-> BB, change from Access port to Trunk port  

2. STP Block works normally after changing the tag-allowed setting of Virtual-Wire.

But I want to know why STP Block is not created when setting the access port when setting the PA-3410 equipment's Virtual Wire.


Is anyone aware of this problem?

Thanks,
