PVST+ Configuration
PVST+ is supported in a VLT domain.
Before you configure VLT on peer switches, configure PVST+ in the network. PVST+ is required for initial
loop prevention during the VLT startup phase. You may also use PVST+ for loop prevention in the
network outside of the VLT port channel.
Run PVST+ on both VLT peer switches. PVST+ instance will be created for every VLAN configured in the
system. PVST+ instances running in the Primary Peer will control the VLT-LAGs on both Primary and
Virtual Link Trunking (VLT)
