OUI
An OUI address is a unique identifier assigned by IEEE (Institute of Electrical and Electronics Engineers) to a device vendor. It
comprises the first 24 bits of a MAC address. You can recognize which vendor a device belongs to according to the OUI
address. The following table shows the OUI addresses of several manufacturers. There is also the option to add a custom one
based on user needs.
Spanning Tree
STP (Spanning Tree Protocol), Devices running STP discover loops in the network and block ports by exchanging information,
in that way, a ring network can be disbranched to form a tree-topological ring-free network to prevent packets from being
duplicated and forwarded endlessly in the network.
BPDU (Bridge Protocol Data Unit) is the protocol data that STP, RSTP and MSTP use. Enough information is carried in BPDU to
ensure the spanning tree generation. STP is to determine the topology of the network via transferring BPDUs between
devices.
This page allows a user to configure and display Spanning Tree Protocol (STP) property configuration including the STP Mode
(STP, RSTP or MSTP), Path Cost, Bridge Priority, Max Hops, Hello and Max Aging time and Forward Delay Time.
