SPANNING TREE ALGORITHM CONFIGURATION

Command 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 3-126for 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:

•Spanning Tree – Enables/disables STA on this interface. (Default: Enabled).

•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 Protocol is detecting network loops. Where more than one port is assigned the highest priority, the port with lowest numeric identifier will be enabled.

-Default: 128

-Range: 0-240, in steps of 16
