802.1w RSTP recommended value: (Valid range: 1 – 200,000,000)

10 Mbps : 2,000,000

100 Mbps : 200,000

1 Gbps : 20,000

Default: 0

Priority:

Priority here means Port Priority. Port Priority and Port Number are

mixed to form the Port ID. Port IDs are often compared in order to

determine which port of a bridge would become the Root Port. The range

is 0 – 240.

Default is 128.

Admin Edge Port:

If user selects “Yes”, this port will be an edge port. An Edge Port is a port

connected to a device that knows nothing about STP or RSTP. Usually,

the connected device is an end station. Edge Ports will immediately

transit to forwarding state and skip the listening and learning state

because the edge ports cannot create bridging loops in the network. This

will expedite the convergence. When the link on the edge port toggles,

the STP topology keeps unchanged. Unlike the designate port or root

port though, an edge port will transit to a normal spanning-tree port

immediately if it receives a BPDU.

Default: No

Admin Point To Point:

We say a port is a point-to-point link, from RSTP’s view, if it is in full-

duplex mode but is shared link if it is in half-duplex mode. RSTP fast

convergence can only happen on point-to-point links and on edge ports.

This can expedite the convergence because this will have the port fast

transited to forwarding state.

There are three parameters, Auto, True and False, used to configure the

type of the point-to-point link. If configure this parameter to be Auto, it

means RSTP will use the duplex mode resulted from the auto-negotiation.

In today’s switched networks, most links are running in full-duplex mode.

For sure, the result may be half-duplex, in this case, the port will not fast

transit to Forwarding state. If it is set as True, the port is treated as point-

to-point link by RSTP and unconditionally transited to Forwarding state. If

it is set as False, fast transition to Forwarding state will not happen on

this port.

Default: Auto
