Port state RSTP STP guard LBD Type Native VLAN Allowed VLANs Tags Link (RJ45) PoE 25 selected, this name will be applied to all ports. Choose to enable or disable the port. Choose to enable or disable Rapid Spanning Tree Protocol (RSTP). RSTP prevents data loops by issuing frequent BPDU packets to monitor link status. Note: RSTP cannot be used in conjunction with LBD. If RSTP is enabled, choose the guard type. Disabled: Do not use root guard enhancement. Root guard: Root guard enhancement allows administrators to define the position of the root bridge port in the network. Choose to enable or disable Loopback Detection (LBD). The Loopback Detection function is used to detect the loop created by a specific port while Spanning Tree Protocol (STP) is not enabled in the network, especially when the down links are hubs or unmanaged switches. The Switch will automatically shut down the port and sends a log to the administrator. Note: LBD cannot be used in conjunction with RSTP. Choose the function type of the port. Trunk: Sends and receives tagged data from different VLANs. Access: Only sends and receives untagged data from the VLAN the port belongs to. Enter the ID of the native VLAN the port belongs to. Enter the IDs of the VLANs that can route traffic through this port. Enter All to allow all traffic from all VLANs to pass through this port. Enter a descriptive tag for the port. Multiple tags can be entered. If multiple ports are selected, any tags will be applied to all ports. Choose the maximum link speed of the port. Select Auto to allow the port to auto-negotiate port speed with the partner port or device. Choose to enable or disable Power over Ethernet

selected, this name will be applied to all ports.
Port state
Choose to enable or disable the port.
RSTP
Choose to enable or disable Rapid Spanning Tree
Protocol (RSTP). RSTP prevents data loops by
issuing frequent BPDU packets to monitor link status.
Note
: RSTP cannot be used in conjunction with LBD.
STP guard
If RSTP is enabled, choose the guard type.
Disabled
: Do not use root guard enhancement.
Root guard
: Root guard enhancement allows
administrators to define the position of the root bridge
port in the network.
LBD
Choose to enable or disable Loopback Detection
(LBD). The Loopback Detection function is used to
detect the loop created by a specific port while
Spanning Tree Protocol (STP) is not enabled in the
network, especially when the down links are hubs or
unmanaged switches. The Switch will automatically
shut down the port and sends a log to the
administrator.
Note
: LBD cannot be used in conjunction with RSTP.
Type
Choose the function type of the port.
Trunk
: Sends and receives tagged data from different
VLANs.
Access
: Only sends and receives untagged data from
the VLAN the port belongs to.
Native VLAN
Enter the ID of the native VLAN the port belongs to.
Allowed VLANs
Enter the IDs of the VLANs that can route traffic
through this port. Enter
All
to allow all traffic from all
VLANs to pass through this port.
Tags
Enter a descriptive tag for the port. Multiple tags can
be entered. If multiple ports are selected, any tags will
be applied to all ports.
Link (RJ45)
Choose the maximum link speed of the port. Select
Auto
to allow the port to auto-negotiate port speed
with the partner port or device.
PoE
Choose to enable or disable Power over Ethernet
