What is VSTP in Juniper?

VLAN Spanning Tree Protocol (VSTP) enables Juniper Networks 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. You can configure VSTP for a maximum of 509 VLANs. VSTP and RSTP can be configured at the same time.

Does Juniper support PVST?

Cisco supports a proprietary Per-VLAN Spanning Tree (PVST) protocol, which maintains a separate spanning tree instance per each VLAN. PVST runs on Cisco proprietary ISL trunks which is not supported by Juniper. Juniper switches only inter-operate with PVST+ and Rapid-PVST+.

How do I set priority in Rstp?

Steps: How to Configure STP/RSTP on UniFi Network

  1. Navigate to Devices section of the UniFi Network application and click on the switch in which you wish to change the priority to open its Properties Panel.
  2. Navigate to Config (gear icon) > Services > Spanning Tree.

How do I enable STP on a Juniper switch?

Enable STP either on all interfaces or on a specific interface:

  1. To enable STP on all interfaces: [edit protocols] user@switch# set stp interface all.
  2. To enable STP on a specific interface: [edit protocols] user@switch# set stp interface interface-name.

What is VLAN STP?

Introduction. Spanning Tree Protocol (STP) prevents loops in networks and VLAN (Virtual Local Area Network) is used to create many virtual Local Area Networks. Redundant links are helpful in networks as backups in failover cases. When the primary link fails, the backup (redundant) link is activated.

What is the difference between Pvst and Pvst+?

Per VLAN Spanning Tree (PVST) is a Cisco proprietary protocol that allows a Cisco device to have multiple spanning trees. PVST+ is an extension of PVST that allows a Cisco device to also interoperate with devices that are running a single spanning tree (IEEE 802.1Q).

How do I know if my juniper switch is STP?

Checking the Status of Spanning-Tree Instance Interfaces

  1. To check the status of spanning-tree instance interface, use the show interfaces command: user@host> show interfaces interface-name.
  2. You can determine the status of the interface as follows: If the BPDU Error field is none, the interface is enabled.

What is the RSTP configuration with VSTP in Junos?

RSTP configuration with VSTP was Introduced in Junos OS Release 10.2 (Release Note Feature from 10.2) RSTP configuration with VSTP—VSTP and RSTP can now be configured concurrently. When VSTP and RSTP are configured concurrently, the first 253 VLANs are configured with VSTP and the remaining VLANs are configured using RSTP.

What is the default configuration file for the EX4200 switch?

The default configuration file sets values for system parameters such as syslog and commit; configures Power over Ethernet (PoE), storm control, and Ethernet switching on all interfaces; and enables the LLDP and RSTP protocols. Configuring Junos OS on the EX4200 | EX4200 Switch Hardware Guide | Juniper Networks TechLibrary X

How many VLANs can a juniper switch support?

On an EX Series switch running Junos OS that does not support ELS—VSTP can support up to 253 VLANs. You can use Juniper Networks switches with VSTP and Cisco switches with PVST+ and Rapid-PVST+ in the same network. Cisco supports a proprietary Per-VLAN Spanning Tree (PVST) protocol, which maintains a separate spanning tree instance per each VLAN.

Does juniper support per-VLAN spanning trees?

Cisco supports a proprietary Per-VLAN Spanning Tree (PVST) protocol, which maintains a separate spanning tree instance per each VLAN. One Spanning Tree per VLAN allows fine grain load balancing but requires more BPDU CPU processing as the number of VLANs increases. PVST runs on Cisco proprietary ISL trunks which is not supported by Juniper.
