Based on the location of the root bridge, theother switches determine which of their ports has the lowest path cost to the root bridge. These ports are called root ports, and each switch (other than the current root bridge) must have one.
STP stand for Spaning Tree Protocol. It's used to avoid the L2 loop in the network. many factor are belong to STP. such as Root Switch, BPDU, Root Port, Forward port, blocking port.
Spanning-Tree Protocol (STP)
A spanning tree protocol, or STP, is characteristic to a LAN. It provides a loop-free topology for networks within the system.
root primary
The switch is receiving BPDUs and populating the MAC address table, but not sending data.

d. A broadcast storm
the disadvantage os stp that it is time consuming.
Allows for redundant links by eliminating loops.
Catalyst switches have support for several technologies that may be used in larger networks, and that are not available on home switches - for example, VLANs, and STP (Spanning-Tree Protocol), as well as options for port security.Catalyst switches have support for several technologies that may be used in larger networks, and that are not available on home switches - for example, VLANs, and STP (Spanning-Tree Protocol), as well as options for port security.Catalyst switches have support for several technologies that may be used in larger networks, and that are not available on home switches - for example, VLANs, and STP (Spanning-Tree Protocol), as well as options for port security.Catalyst switches have support for several technologies that may be used in larger networks, and that are not available on home switches - for example, VLANs, and STP (Spanning-Tree Protocol), as well as options for port security.
