The port table can be used to inspect the following values for all available ports (LAN, wireless LAN, point-to-point connections).
- Priority The priority of this port taken from the port configuration
- StatusThe current state of the port:
- Disabled: No packets can be sent or received through this port. This occurs when the port has either been disabled manually or when it has a negative link status.
- Listening: Intermediate state on the way to enabling. Only Spanning Tree packets are listened to, data packets are ignored and are also not forwarded to this port.
- Learning: Another intermediate state. As opposed to 'listening' additional MAC addresses from data packets entering this port are learned but data packets are still not forwarded.
- Forwarding: The port is completely active, data packets are received and forwarded in both directions
- Blocking: Spanning Tree has identified this port to be redundant and disabled it for data traffic.
- RootThe ID for the root bridge that can be reached through this port.
- BridgeThis is the ID for the bridge through which the root bridge can be reached.
- CostsThis value defines the 'costs' for this port. The value is determined by the port technology (Ethernet, WLAN, etc.) and the bandwidth. Examples of values used are:
Transfer technology Costs of Classic Spanning Tree Costs of Rapid Spanning Tree Ethernet 10 MBit 100 2000000 Ethernet 100 MBit 19 200000 Ethernet 1000 MBit 4 200000 WLAN 2 MBit 500 12500000 WLAN 11 MBit 140 4000000 WLAN 54 MBit 35 900000 WLAN 108 MBit 25 450000 Note: If path costs for a port were manually entered, then the configured value appears in this column.
