Port Configuration - 802.1X Tab
802.1x port security requires a user connected to a port on the network to be authenticated by
an authentication server.
When a user connects to a port configured with 802.1x port security, the port forwards an
authentication packet to a Radius authentication server. The authentication server checks if the
user is authorized to use the port, and either allows or blocks the user’s access to the port.
The port can be configured to automatically reauthenticate the user. If the reauthentication fails,
the user is denied further access to the port. For more information, refer to
“Port Configuration -
General Tab” on page 49 .
STP Admin Path
Cost The administratively assigned value for the contribution of this port to
the path cost of paths towards the spanning tree root. A value of 0
assigns the automatically calculated default Path Cost value to the
port.
STP Admin Path Cost complements STP Path Cost, which returns
the operational value of the path cost.
STP Path Cost The operational cost factor used by Spanning Tree Algorithm to
determine the most efficient route for forwarding traffic to its
destination while removing loops in the network.For more
information, refer to Spanning Tree Algorithm (STA) in The Reference
Guide.
STP Priority The priority factor used by STP to determine the activity status of an
individual port on the Spanning Tree.
STP Force Migration When checked and in RSTP mode, the port is forced to transmit
RSTP BPDUs.
Port Classification The classification of a specific port. Port Classification allows network
managers to specify each port level’s importance. The possible
states are:
● Regular - Normal Users
● Valuable - Servers or critical users.
For more information refer to Port Classification in The Reference
Guide.
