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 recei-
ves a BPDU.
Default: No
Admin Point To Point: 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 For-
warding state will not happen on this port.
Default: Auto
M Check:
Migration Check. It forces the port sending out an RSTP BPDU instead of
a legacy STP BPDU at the next transmission. The only benefit of this ope-
