OS for EX Series Ethernet Switches, Release 10.4
The default spanning-tree protocol for EX Series switches is Rapid Spanning Tree Protocol
(RSTP). RSTP provides faster convergence times than Spanning Tree Protocol (STP).
However, some legacy networks require the slower convergence times of basic STP.
If your network includes 802.1D 1998 bridges, you can remove RSTP and explicitly
configure STP. When you explicitly configure STP, the EX Series switches use the IEEE
802.1D 2004 specification, force version 0. This configuration runs a version of RSTP that
is compatible with the classic, basic STP.
To configure STP using the CLI:
Delete the RSTP configuration on the interface (here, the interface is

user@switch# delete protocols rstp interface ge-0/0/5
Configure STP on the interface:

EX Series switches provide Layer 2 loop prevention through Spanning Tree Protocol
(STP), Rapid Spanning Tree Protocol (RSTP), Multiple Spanning Tree Protocol (MSTP),
and VLAN Spanning Tree Protocol (VSTP). You can configure STP, RSTP, and MSTP
using the J-Web interface. You can configure bridge protocol data unit (BPDU) protection
on interfaces to prevent them from receiving BPDUs that could result in STP
misconfigurations, which could lead to network outages.
To configure STP, MSTP, or RSTP for an EX Series switch using the J-Web interface:
Select Configure > Switching

The Spanning Tree Configuration page displays the spanning-tree protocol
configuration parameters and a list of interfaces configured for each spanning-tree
protocol configuration.
