VLAN Spanning tree issue

vyl-coyot
Level 1
Level 1

Hello,

I have issues with my VLAN 200 on 1 of my 2 switch, they are configured as client VTP and get the same VLAN from my Backbone switch. These two switch has almost same configuration (swihv33 has just more VLAN allowed than swihv31).

So i have extract some configuration and made a schema of the topology (photo below).

On my switch swihv33 the vlan 200 works fine and i can get an IP from my DHCP for example but i get nothing on my switch swihv31. The only thing that i noticed in spanning-tree configuration that is one (swihv31) is with Desg role on the interface Po1 and the other one (swihv33) is with Root role on interface Po1 :

Any idea, why it works on 1 and not on the other ?

Post VTP information from all the switches, looks like some VTP sync version mismatch or database not syncing ?

Do you have any config related to VLAN 200 on local switch like any priority setup that to become as root bridge ?

what  IOS XE code running, i am guessing all should be same IOS XE code and same VTP Version,
