Description
Configures the port priority. The port priority helps determine which bridge
port becomes the designated port.
In a network topology that has multiple bridge ports connected to a single
segment, the port with the lowest port priority becomes the designated port
for the segment.
The range is 0 to 255, and the default is 128.
RSTP/MSTP: The range is 0 to 240, in steps of 16 (0, 16, 32...) and the
default is 128.
Configures the port path cost. The port path cost is used to help determine the
designated port for a segment. Generally speaking, the faster the port, the
lower the path cost.
The range is 1 to 65535. The default is 100 for 10Mb ports, 10 for 100 Mb
ports, 4 for Gigabit ports, and 2 for 10Gb ports.
A value of 0 indicates that the default cost will be computed for an auto-
negotiated link speed.
RSTP/MSTP: The range is 1 – 200000000, and the default it 20000 for
Gigabit ports, 2000 for 10Gb ports.
Defines the type of link connected to the port, as follows:
•
auto—Configures the port to detect the link type, and automatically
match its settings.
•
p2p—Configures the port for Point-To-Point protocol.
•
shared—Configures the port to connect to a shared medium (usually a
hub).
This command only applies when RSTP is turned on. See the "Common
Internal Spanning Tree configuration" section for more information.
Enables or disables this port as an edge port. An edge port is not connected
to a bridge, and can begin forwarding traffic as soon as the link is up.
Configure server ports as edge ports (enabled).
This command only applies when RSTP is turned on. See the "Common
Internal Spanning Tree configuration" section for more information.
Enables or disables Port Fast Forward on the port.
Enables STP on the port.
Disables STP on the port.
Displays the current STP port parameters.
