Priority: Specify the priority of each port. Selectable range is from 0 to 240, and the default setting is 128.
The lower the number, the greater the probability the port will be chosen as a root port.
P2P: Choosing the True parameter indicates a point-to-point (P2P) shared link. P2P ports are similar to edge
ports however they are restricted in that a P2P port must operate in full-duplex.
Like edge ports, P2P ports transition to a forwarding state rapidly thus benefiting from RSTP. A p2p value of
false indicates that the port cannot have p2p status. Auto allows the port to have p2p status whenever
possible and operate as if the p2p status were true. If the port cannot maintain this status, (for example if the
port is forced to half-duplex operation) the p2p status changes to operate as if the p2p value were
False . The
default setting for this parameter is Auto .
Restricted Role: Toggle between True and False to set the restricted role state of the packet. If set to True ,
the port will never be selected to be the Root port. The default value is False .
Restricted TCN: Toggle between True and False to set the restricted TCN of the packet. Topology Change
Notification (TCN) is a BPDU that a bridge sends out to its root port to signal a topology change. If set to
True , it stops the port from propagating received TCN and to other ports. The default value is False .

L2 Functions > Link Aggregation > Port Trunking
The Trunking function enables the combining of two or more ports together to increase bandwidth. Up to
eight Trunk groups may be created, and each group consists up to eight ports.
Figure 5.43 – L2 Functions > Link Aggregation > Port Trunking
Link Aggregation State: Enable or Disable the Link Aggregation state.
ID: Specifies the Trunking ID.
Type: Specifies the Link Aggregation type. There are two types can be selected:
Static - Static link aggregation.
LACP - LACP (Link Aggregation Control Protocol) is enabled on the device. LACP allows for the
automatic detection of links in a Port Trunking Group.
Select the ports to be grouped together, and then click Apply to activate the selected Trunking groups.
NOTE: Each combined trunk port must be
connected to devices within the same VLAN
group.
L2 Functions > Link Aggregation > LACP Port Settings
The LACP Port Settings is used to create port trunking groups on the Switch. The user may set which ports
will be active and passive in processing and sending LACP control frames
