The following table describes the Spanning Tree Port Configuration Menu options.
Table 113 Spanning Tree Port Configuration Menu options
Command
Description
prior <0-255>
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.
cost <0-200000000>
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 0 to 65535. The default is 2 for 10Gb ports except Port 17. A
value of 0 indicates that the default cost will be computed for an auto-
negotiated link speed.
RSTP/MSTP: The range is 0 – 200000000, and the default is 2000 for 10Gb
ports except Port 17.
link auto|p2p|shared
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.
edge disable|enable
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). By default, Ports
1-16 are configured as edge ports.
This command only applies when RSTP is turned on. See the ―Common
Internal Spanning Tree configuration‖ section for more information.
fastfwd disable|enable
Enables or disables Port Fast Forward on the port. The default is disabled.
on
Enables STP on the port. This is the default for Ports 18 - 21.
off
Disables STP on the port.
cur
Displays the current STP port parameters.
