Linksys EF1324 manual Spanning Tree Port Information

Page 50

Instant EtherFast® Series

•Root Cost - The path cost from the root port on this Switch to the root device.

•Root Port - The number of the port on this Switch that is closest to the root. This Switch communicates with the root device through this port. If there is no root port, then this Switch has been accepted as the root device of the Spanning Tree network.

•Configuration Changes - The number of times the Spanning Tree has been reconfigured.

•Topology Up Time - The time since the Spanning Tree was last recon- figured.

Spanning Tree Port Information

The STA Port Information screen displays a summary of STA information for the various ports.

•Port (#) - Number of the port.

•Type - Shows port type as:

100TX 10BaseT/100Base-TX 1000T 1000Base-T

EtherFast® Layer 3 Management 24-Port 10/100 + 2-Port Gigabit Ethernet Switch

• Status - Displays current state of this port within the Spanning Tree:

Disabled	No link has been established on this port.
	Otherwise, the port has been disabled by the user
	or has failed diagnostics.
Blocking	Port received STA configuration messages, but
	does not forward packets.
Listening	Port will leave blocking state due to a topology
	change. It starts transmitting configuration mes-
	sages, but does not yet forward packets.
Learning	Port has transmitted configuration messages for an
	interval set by the Forward Delay parameter with
	out receiving contradictory information. Port
	address is cleared, and the port begins learning
	addresses.
Forwarding	The port forwards packets, and continues learning
	addresses.

•Designated Cost - The cost for a packet to travel from this port to the root in the current Spanning Tree configuration. The slower the media, the higher the cost.

•Designated Bridge (ID) - The priority and MAC address of the device through which this port must communicate to reach the root of the Spanning Tree.

•Designated Port (ID) - The priority and number of the port on the des- ignated bridging device through which this Switch must communicate with the root of the Spanning Tree.

•Root Cost - The path cost from the root port on this Switch to the root device.
