Command Attributes
• STP State — Displays current state of this port within the
Spanning Tree:
- Discarding — Port receives STP 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.
• Priority — Defines the priority used for this port in the
Spanning Tree Protocol. If the path cost for all ports on a switch
is 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)
