Hi and thanks in advance.
I have this issue.(both Juniper & Cisco stack or virtual chassis)
Juniper EX4200 CORE with Ge1/0/8 trunk port with Vlan1 added as native (in order to "talk" with Cisco)
Cisco Catalyst 2960X with Gi5/0/1 trunk Vlan1 native
Cisco 2960X Gi5/0/1 trunk -------------------------------------------------Ge1/0/8 Trunk Juniper EX4200
Trunk allowed Vlan1,100,114,120 Trunk allowed Vlan1,100,114,120
PVST enabled VSTP enabled ALL Vlans
so I get this from Juniper side
Ethernet-switching table: 6 unicast entries

as you can see everytime I refresh the command it connects, disconnects, and so
Same Cisco side
What seems to ne the problem?
before this I had RSTP on Juniper and ports blocked, NOW with VSTP I can see ports BUT get disconnected???
