Signamax 065-7840 24-Port 10/100/1000BaseT/TX Managed Switch
98
802.1w RSTP recommended values: (Valid range: 1 – 200,000,000)
10 Mbps : 2,000,000
100 Mbps: 200,000
1 Gbps : 20,000
Default: 0
Priority:
Priority, in this case, means Port Priority. Port Priority and Port Number
are combined to form the Port ID. Port IDs are often compared to
determine which port of a bridge would become the Root Port. The valid
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 remains unchanged. However, unlike the designate
port or root port, an edge port will transit to a normal spanning-tree port
immediately if it receives a BPDU.
Default: No
Admin Point To Point:
From the RSTP’s point of view, a port is a point-to-point link if it is in full-
duplex mode but is a 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 allow the port to fast
transit to the forwarding state.
There are three parameters, Auto, True and False, used to configure the
type of the point-to-point link. If this parameter is configured to be Auto, it
means RSTP will use the duplex mode that resulted from the auto-
negotiation. In today’s switched networks, most links are running in full-
duplex mode. The result may be half-duplex, however; in this case, the
port will not fast transit to the Forwarding state. If this parameter is set as
True, the port is treated as a point-to-point link by RSTP and
unconditionally transited to the Forwarding state. If the parameter is set
as False, fast transition to the Forwarding state will not happen on this
port.
Default: Auto
