Configuring VLAN Spanning Tree Protocol (CLI Procedure)
VLAN Spanning Tree Protocol (VSTP) allows 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:
1.
(Optional) Enable Rapid Spanning Tree Protocol (RSTP):
[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.
2.
Enable VSTP.
