63.4.1 MSTP Command Examples
This example shows the current MSTP configuration.
The following table describes the labels in this display.
mstp instance <0-16> interface
port-channel < aid > path-cost <1-
65535>
Specifies the cost of transmitting a frame to a
LAN through the port(s). It is recommended you
assign it according to the speed of the bridge.
aid

msc-< slot >-< port >
C 13
mstp instance <0-16> interface
port-channel < 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.

LABEL DESCRIPTION
BridgeMaxAge This field displays the maximum time (in seconds) the OLT can wait without receiving a
configuration message before attempting to reconfigure.
BridgeHelloTime This field displays the time interval (in seconds) at which the OLT transmits a
configuration message.
BridgeForwardDelay This field displays the time (in seconds) the OLT will wait before changing states (that is,
listening to learning to forwarding).
BridgeMaxHops This field displays the number of hops (in seconds) in an MSTP region before the BPDU is
discarded and the port information is aged.
TransmissionLimit This field displays the maximum number of BPDUs that can be transmitted in the interval
specified by
BridgeHelloTime .
ForceVersion This field indicates whether BPDUs are RSTP (a value less than 3) or MSTP (a value
greater than or equal to 3).
MST Configuration ID
Format Selector This field displays zero, which indicates the use of the fields below.
Configuration Name This field displays the configuration name for this MST region.
