To delete a single MAC address, click the Delete button next to the corresponding MAC address.
To delete a batch of MAC address concurrently, check corresponding check boxes and click Batch
Delete.

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 can not be added to the Filtering Address Table.
3. Once VLAN mode is toggled, all current settings will be cleared.
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 changes, introducing new convergence behaviors and bridge port roles to do this. RSTP is
designed to be backwards-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
