spanning-tree edge-port command is used to
spanning-tree edge-port
command is used to set the operEdge flag should
start
as set. (The initial operEdge state when a port is initialized). “
no
spanning-tree edge-port
“ command is used to set the operEdge flag should
start as cleared. operEdge flag is an operational flag describing whether the
port is connecting directly to edge devices. (No Bridges attached). Transition
to the forwarding state is faster for edge ports (having operEdge true) than for
other ports.
spanning-tree mcheck
command is used to restart the STP Migration Check
for the ports. If at any time the switch detects STP BPDUs, it will
automatically set the selected interface to forced STP-compatible mode.
However, you can use the command to manually re -check the appropriate
BPDU format to send on the selected interfaces (i.e., RSTP or STP -
compatible).
spanning-tree msti x cost [auto | specific y]
command is used to set the the
path cost incurred by the ports
in MSTI “x”. “
x
” is the index of MSTI with value
0~7. “
y
” is cost value in range 1~200000000. The “
auto
” setting will set the
path cost as appropriate by the physical link speed, using the 802.1D
recommended values.
spanning-tree msti x port_priority y
command is used to set the port priority
of the ports
in MSTI “x”. “
x
” is the index of MSTI with value 0~7. “
y
” is priority
value in range 0~240. This can be used to control priority of ports having
identical port cost.
spanning-tree p2p [auto | false | true]
command is used to set the ponit-to-
point connection mode for the ports. If the ports connects to a point-to-point
LAN rather than to a shared medium, the ponit-to-point connection mode is
true. This can be automatically determined, or forced either true or false.
Transition to the forwarding state is faster for point-to-point LANs than for
shared media.
spanning-tree restrictedrole
command is used to enable the ports as
restricted role in MSTP. If enabled, causes the port not to be selected as
Root Port for the CIST or any MSTI, even if it has the best spanning tree priority
vector. Such a port will be selected as an Alternate Port after the Root P ort has
been selected. If set, it can cause lack of spanning tree connectivity. It can be
set by a network administrator to prevent bridges external to a core region of
the network influence the spanning tree active topology, possibly because
those bridges are not under the full control of the administrator. This feature
is also known as Root Guard. “
no spanning-tree restrictedrole
“ command
is used to disable it.
spanning-tree restrictedtcn
command is used to enable the ports as
restricted TCN in MSTP. If enabled, causes the port not to propagate
received topology change notifications and topology changes to other ports. If
