Forcing RSTP or VSTP to Run as IEEE 802.1D STP (CLI Procedure)
 | Note: This procedure uses Junos OS for EX Series switches with support for the Enhanced Layer 2 Software (ELS) configuration style. For ELS details, see Getting Started with Enhanced Layer 2 Software. |
On EX Series switches running Rapid Spanning Tree Protocol (RSTP) (the default) or VLAN Spanning Tree Protocol (VSTP), you can force the original IEEE 802.1D Spanning Tree Protocol (STP) version to run in place of RSTP or VSTP. Configure the force-version stp statement for compatibility with older bridges that do not support RSTP or VSTP.
To force the spanning-tree protocol version to be the original IEEE 802.1D STP:
- Enable IEEE 802.1D STP:
[edit protocols]
user@switch# set (rstp | vstp) force-version stp
| Note: After using the force-version statement to enable xSTP globally, apply the force-version statement for specific Layer 2 ports. |
