492 Section IV: Spanning Tree Protocols
edgeport Defines whether the port is functioning as an edge port.
An edge port is connected to a device operating at half-
duplex mode and is not connected to any device
running STP or MSTP. Selections are:
yes, on, true The port is an edge port. These
values are equivalent. This is the
default.
no, off, false The port is not an edge port. These
values are equivalent.
ptp or Defines whether the port is functioning as a point-to-
pointtopoint point port. This type of port is connected to a device
operating at full-duplex mode. Selections are:
yes, on, true The port is an point-to-point port.
no, off, false The port is not an point-to-point port.
autoupdate The port’s status is determined
automatically. This is the default.
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.
yes, on, true Enable migration check. The values
are equivalent.
no, off, false Disable migration check. The values
are equivalent.
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.
intportcost Specifies the cost of a port connected to a bridge that is
part of the same MSTP region. This is referred to as an
internal port cost. The range is 0 to 200,000,000. The
default setting is Auto-detect (0), which sets port cost
depending on the speed of the port. Default values are
2,000,000 for 10 Mbps ports, 200,000 for a 100 Mbps
ports, and 20,000 for one gigabit ports.
