ONFIGURING THE
- 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
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
• Path Cost - This parameter is used by the STA to determine the best
path between devices. Therefore, lower values should be assigned to
ports attached to faster media, and higher values assigned to ports with
slower media. (Path cost takes precedence over port priority.) Note that
when the Path Cost Method is set to short (page 4-212), the maximum
path cost is 65,535.
- Range:
- Ethernet: 200,000-20,000,000
- Fast Ethernet: 20,000-2,000,000
- Gigabit Ethernet: 2,000-200,000

- Default:

- Ethernet - Half duplex: 2,000,000; full duplex: 1,000,000;
trunk: 500,000
- Fast Ethernet - Half duplex: 200,000; full duplex: 100,000;
trunk: 50,000
- Gigabit Ethernet - Full duplex: 10,000; trunk: 5,000
