To delete a single MAC address, click the

.
Note
:
1.
A certain interface’s MAC address and VLAN ID can be bound to another interface.
2.
The MAC address in the Static Address Table cannot be added to the Filtering Address Table.
3.
Static MAC address will be cleared once you switch VLAN mode.
4.
A certain interface in the static MAC address table can receive packets whose source MAC address matches
its corresponding VID; packets whose destination MAC address matches the corresponding VID can only be
forwarded to the corresponding interface.
4.6.2 STP
STP Overview
The Spanning Tree Protocol (STP) is a network protocol that ensures a loop-free topology for any bridged Ethernet
local area network. The basic function of STP is to prevent bridge loops and the broadcast radiation that results
from them. On Ethernet, only a single active path at a time can be maintained between any two network nodes to
avoid broadcast storm. However, spare (redundant) links are indispensable to ensure reliability. Spanning tree
allows a network design to include spare (redundant) links to provide automatic backup paths if an active link fails,
without the danger of bridge loops, and disable those that are not part of the spanning tree, leaving a single active
path between any two network nodes. This is accomplished in the STP. A STP-enabled switch can perform the
following tasks:
1. Discover and generate an optimum STP topology.
2. Discover and repair failures on the network; automatically update the network topology for future use. Local
topology is generated by computing bridge configurations made by a network administrator. Thus, if configured
properly, an optimum topology tree can be generated.
RSTP Overview
RSTP (Rapid Spanning Tree Protocol) provides significantly faster spanning tree convergence after a topology
change, introducing new convergence behaviors and bridge port roles to do this. RSTP was designed to be
backward compatible with standard STP. RSTP is typically able to respond to changes within one second while
STP can take 30 to 50 seconds to respond to a topology change.
RSTP delivers fast transition to forwarding status without relying on timer settings. A RSTP bridge is responsive to
other RSTP bridge's link status. The port does not need to wait for the topology to become stable. Edge port and
P2P port are introduced to the protocol for faster transition. Below explains Edge port and P2P port, and their
functions.
Edge Port
The edge port is a configurable designation port that is directly connected to a segment where a loop cannot be
created. Usually it would be a port connected directly to a single workstation. Ports that are designated as edge
ports transition to a forwarding state immediately without going through the listening and learning states. An edge
port loses its status if it receives a BPDU packet, immediately becoming a normal spanning tree port.
P2P Port
