TP-Link TL-SG5412F User Manual

Port Role: Displays the role of the po
rt played in the STP Instance.
 Root Port: Indicates the port that has the lowest path cost
from this bridge to the Root Bridge and forwards packets to
the root.
 Designated Port: Indicates the port that forwards packets to
a downstream network segment or switch.
 Master Port: Indicates the port that connects a MST region
to the common root. The path from the master port to the
common root is the shortest path between this MST region
and the common root.
 Alternate Port: Indicates the port that can be a backup port
of a root or master port.
 Backup Port: Indicates the port that is the backup port of a
designated port.
 Disabled: Indicates the port that is not participating in the
STP.
Port Status: Displays the working status of the port.
 Forwarding: In this status the port can receive/forward data,
receive/send BPDU packets as well as learn MAC address.
 Learning: In this status the port can receive/send BPDU
packets and learn MAC address.
 Blocking: In this status the port can only receive BPDU
packets.
 Disconnected: In this status the port is not participating in
the STP.
LAG: Displays the LAG number which the port belongs to.
Note:
1. Configure the ports connected directly to terminals as edge ports and enable the BPDU
protection function as well. This not only enables these ports to transit to forwarding state
rapidly but also secures your network.
2. All the links of ports in a LAG can be configured as point-to-point links.
3. When the link of a port is configured as a point-to-point link, the spanning tree instances
owning this port are configured as point-to-point links. If the physical link of a port is not a
point-to-point link and you forcibly configure the link as a point-to-point link, temporary loops
may be incurred.
7.3 MSTP Instance
MSTP combines VLANs and spanning tree together via VLAN-to-instance mapping table
(VLAN-to-spanning-tree mapping). By adding MSTP instances, it binds several VLANs to an
instance to realize the load balance based on instances.
Only when the switches have the same MST region name, MST region revision and
VLAN-to-Instance mapping table, the switches can be regarded as in the same MST region.
The MSTP Instance function can be implemented on Region Config, Instance Config and
Instance Port Config pages.
