Table 235 STP and RSTP Commands
COMMAND DESCRIPTION M P
show spanning-tree config
Displays Spanning Tree Protocol (STP) settings. E 3
spanning-tree mode <RSTP|MSTP>
Specifies the STP mode you want to implement
on the OLT.
C13
spanning-tree
Enables STP on the OLT. C 13
no spanning-tree
Disables STP on the OLT. C 13
spanning-tree hello-time <1-10>
maximum-age <6-40> forward-delay
<4-30>
Sets Hello Time, Maximum Age and Forward
Delay.
hello-time: The time interval in seconds
between BPDU (Bridge Protocol Data Units)
configuration message generations by the root
switch.
maximum-age: The maximum time (in seconds)
the OLT can wait without receiving a BPDU
before attempting to reconfigure.
forward-delay: The maximum time (in
seconds) the OLT will wait before changing
states.
C13
spanning-tree priority <0-61440>
Sets the bridge priority of the OLT. The lower the
numeric value you assign, the higher the priority
for this bridge.
priority: Must be a multiple of 4096.
C13
spanning-tree <aid>
Enables STP on a specified ports.
aid: slot-<slot> | msc-<slot>-<port>
C13
no spanning-tree <aid>
Disables STP on listed ports. C 13
spanning-tree <aid> edge-port
Sets the specified ports as edge ports. This allows
the port to transition to a forwarding state
immediately without having to go through the
listening and learning states.
Note: An edge port becomes a non-edge
port as soon as it receives a Bridge
Protocol Data Units (BPDU).
C13
no spanning-tree <aid> edge-port
Sets the listed ports as non-edge ports. C 13
spanning-tree <aid> path-cost <1-
65535>
Specifies the cost of transmitting a frame to a
LAN through the port(s). It is assigned according
to the speed of the bridge.
C13
spanning-tree <aid> priority <0-
255>
Sets the priority for the specified ports. Priority
decides which port should be disabled when
more than one port forms a loop in a OLT. Ports
with a higher priority numeric value are disabled
first.
C13
spanning-tree help
Provides more information about the specified
command.
