Configuring Interface Settings for MSTP
You can configure the STA interface settings for an MST Instance using the MSTP
Port Configuration and MSTP Trunk Configuration pages.
Field Attributes
The following attributes are read-only and cannot be changed:
• STA State – Displays current state of this port within the Spanning Tree.
(See Displaying Interface Settings on page 10-10 for additional information.)
• Discarding - Port receives STA configuration messages, but does not forward
packets.
• Learning - Port has transmitted configuration messages for an interval set by
the Forward Delay parameter without receiving contradictory information. Port
address table is cleared, and the port begins learning addresses.
• Forwarding - Port forwards packets, and continues learning addresses.
• Trunk – Indicates if a port is a member of a trunk.
(STA Port Configuration only)
The following interface attributes can be configured:
• MST Instance ID – Instance identifier to configure. (Range: 0-4094; Default: 0)
• Priority – Defines the priority used for this port in the Spanning Tree Protocol. If
the path cost for all ports on a switch are the same, the port with the highest priority
(i.e., lowest value) will be configured as an active link in the Spanning Tree. This
makes a port with higher priority less likely to be blocked if the Spanning Tree
