DESCRIPTION
Displays Spanning Tree Protocol (STP) settings.
Specifies the STP mode you want to implement
on the OLT.
Enables STP on the OLT.
Disables STP on the OLT.
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.
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.
Enables STP on a specified ports.
aid: slot-<slot> | msc-<slot>-<port>
Disables STP on listed ports.
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).
Sets the listed ports as non-edge ports.
Specifies the cost of transmitting a frame to a
LAN through the port(s). It is assigned according
to the speed of the bridge.
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.
Provides more information about the specified
command.
