VLAN Spanning Tree Protocol (VSTP) allows J-EX Series switches to run one or more
Spanning Tree Protocol (STP) or Rapid Spanning Tree Protocol (RSTP) instances for
each VLAN on which VSTP is enabled. For networks with multiple VLANs, VSTP improves
intelligent tree spanning by defining best paths within the VLANs instead of within the
entire network.
To configure VSTP:
(Optional) Enable Rapid Spanning Tree Protocol (RSTP):
1.
[edit protocols]
user@switch# set rstp
VSTP can run on a maximum of 253 VLANs; RSTP runs on the remaining VLANs if
configured. Enabling RSTP ensures that a spanning-tree protocol runs on all VLANs.
Enable VSTP.

Your Action
1. In the Interfaces box, click
an interface from the list, or select an
interface from the list and click
2. Specify the link cost to determine which
bridge is the designated bridge and which
interface is the designated interface.
3. Specify the interface priority to determine
which interface is elected as the root port.
4. If you want to disable the interface, select
the check box.
5. Click OK.
To delete an interface configuration, select the
