Viewing Switch Port Configuration
- Viktoryia Varapayeva (Deactivated)
The Port Config page (Device Viewer > Switch > Port Config) lists all the ports on the chosen switch, the VLAN provisioned for each port, and basic information such as the port state, the Port Fast state, and the administrative and operational state of each switch port (Up or Down). Non-normal data appears in red. The port state can show one of five different values, as follows:
Forwarding: The port is sending and receiving user data.
Learning: The switch is building the bridging table.
Listening:Â The switch port is sending and receiving bridging PDUs in an effort to determine the active switching topology.
Blocking:Â Where the port is only allowed to receive bridging PDUs but otherwise passes no user traffic.
Disabled:Â The port is administratively down.
In a stable spanning-tree network, only Blocking and Forwarding states will typically be seen. The Forwarding state is the only state in which the switch port transmits user data PDUs.
The Interface column provides links to the Interface viewer for every switch port. The VLAN ID and VLAN Name columns column provides links to the VLAN viewer, in which you see the list of devices participating in the VLAN.
