Chapter 15: MSTP Commands
180
migrationcheck This parameter resets a MSTP port, allowing it to
send MSTP BPDUs. When a MSTP bridge receives
STP BPDUs on an MSTP port, the port transmits STP
BPDUs. The MSTP port continues to transmit STP
BPDUs indefinitely. Set the migrationcheck
parameter to yes to reset the MSTP port to transmit
MSTP BPDUs.
Note
Each time a MSTP port is reset by receiving STP BPDUs, set the
migrationcheck parameter to yes, allowing the port to send MSTP
BPDUs.
Description
This command sets a port’s MSTP settings.
Examples
The following command sets the internal port cost to 1,000,000 and port
priority to 224 (increment 14) for Port 4 on the line card in Slot 9:
set mstp port=9.4 intportcost=1000000
portpriority=14
The following command changes Ports 6 to 8 on the line card in Slot 11
so they are not considered edge ports:
set mstp port=11.6-8 edgeport=no
The following command returns Port 7 on the line card in Slot 2 to the
default MSTP settings:
set mstp port=2.7 default
