Section III: Layer 2 Switching 369
auto: Automatically sets the port cost according to the speed of the
port. This is the default. Table 41 lists the port costs with auto-
detect.
The port cost for a port that is part of a trunk is always 2,000,
regardless of port speed.
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 RSTP. The options
are:
yes, on, true: The port is an edge port. The options are
equivalent.
no, off, false: The port is not an edge port. The options are
equivalent. This is the default.
ptp
Defines whether the port is functioning as a point-to-point port. The
parameters are equivalent. This type of port is connected to a
device operating at full-duplex mode. The options are:
yes, on, true: The port is an point-to-point port. The options are
equivalent.
no, off, false: The port is not an point-to-point port. The
parameters are equivalent. are equivalent.
auto: The port’s status is determined automatically. This is the
default.
migrationcheck
Enables migration check. The purpose of this feature is to return a
port to the RSTP mode from the STP compatible mode. The port
remains in the RSTP mode until the port receives STP BPDU
packets. The keywords, yes, on, true are equivalent and all enable
migration check.
This parameter is not saved in the configuration file on the switch.
