-
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
•
Path Cost
– This parameter is used by the STP 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 3-63), 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
