Description
For Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP), VLAN Spanning Tree Protocol (VSTP), or Multiple Spanning Tree Protocol (MSTP), specifies the interface priority to control which interface is elected as the root port. The interface priority must be set in increments of 16.
Default
The default value is 128.
Options
priority—(Optional) Interface priority. The interface priority must be set in increments of 16.
Range: 0 through 240
Required Privilege Level
routing—To view this statement in the configuration.
routing-control—To add this statement to the configuration.
Release Information
Statement introduced in Junos OS Release 8.4.
Statement updated in Junos OS Release 9.4 for EX Series switches to add VSTP support.
Support for logical systems added in Junos OS Release 9.6.
