A designated port is the ports that goes from the root bridge switch to the edge of the network, so there is always a path from the root bridge to the other end. In contrast to root ports, which goes to the root bridge, instead of away from it. All ports that isn't root ports or designated ports are blocked.
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.
d. A broadcast storm
Allows for redundant links by eliminating loops.
the disadvantage os stp that it is time consuming.
It is only used at Layer 2. It eliminates Layer 2 loops in network topologies.
Designated
In the Rapid Spanning Tree Protocol (RSTP), the forwarding port assigned for every switched Ethernet LAN segment is designated as the "Root Port" if it is the best path to the root bridge. For non-root bridges, the port that connects to the root bridge is elected as the Root Port, while other ports may be put into a Blocking state to prevent loops. The designated port, on the other hand, is the port on a network segment that has the lowest path cost to the root bridge and is responsible for forwarding traffic towards that segment.
STP (Spanning Tree Protocol) is still referred to as STP. However, there are newer variations of STP such as Rapid Spanning Tree Protocol (RSTP) and Multiple Spanning Tree Protocol (MSTP).
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.
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.
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.
The port will rapidly transition to forwarding.
