Edit Rapid Spanning Tree Page
The
Edit Rapid Spanning Tree Page
contains the following fields:
•
Interface
— Specifies whether Rapid STP is enabled is enabled on a port or LAG.
•
Role
— Indicates the port role assigned by the STP algorithm in order to provide to STP
paths. The possible field values are:
–
Root
— Provides the lowest cost path to forward packets to root switch.
–

to the LAN.
–
Alternate
— Provides an alternate path to the root switch from the root interface.
–
Backup
— Provides a backup path to the designated port path toward the Spanning

to-point link. Backup ports also occur when a LAN has two or more connections
connected to a shared segment.
–
Disable
— Indicates the port is not participating in the Spanning Tree.
•
Mode
— Indicates the current Spanning Tree mode. The possible field values are:
–
STP
— Indicates that Classic STP is enabled on the port.
–
Rapid STP
— Indicates that Rapid STP is enabled on the port.
•
Fast Link Operational Status
— Indicates if Fast Link is enabled or disabled for the port or
