xStack DGS/DXS-3300 Series Layer 3 Stackable Gigabit Ethernet Switch CLI Manual

config stp mst_ports
Parameters <portlist> - Specifies a port or range of ports to be configured. The
port list is specified by listing the lowest switch number and the
beginning port number on that switch, separated by a colon. Then
the highest switch number, and the highest port number of the
range (also separated by a colon) are specified. The beginning
and end of the port list range are separated by a dash. For
example, 1:3 specifies switch number 1, port 3. 2:4 specifies
switch number 2, port 4. 1:3-2:4 specifies all of the ports between
switch 1, port 3 and switch 2, port 4 − in numerical order.
instance_id <value 0-15> - Enter a numerical value between 0 and
15 to identify the instance_id previously configured on the Switch.
An entry of 0 will denote the CIST (Common and Internal
Spanning Tree.
internalCost – This parameter is set to represent the relative cost
of forwarding packets to specified ports when an interface is
selected within a STP instance. The default setting is auto. There
are two options:
auto – Selecting this parameter for the internalCost will
set quickest route automatically and optimally for an
interface. The default value is derived from the media speed
of the interface.
value 1-2000000 – Selecting this parameter with a value
in the range of 1-2000000 will set the quickest route when a
loop occurs. A lower internalCost represents a quicker
transmission.
priority <value 0-240> - Enter a value between 0 and 240 to set
the priority for the port interface. A higher priority will designate the
interface to forward packets first. A lower number denotes a
higher priority.
Restrictions Only administrator-level users can issue this command.
Example usage:
To designate ports 1 through 5 on module one, with instance ID 2, to have an auto internalCost and a priority of 16:
DGS-3324SRi:4#config stp mst_config_id ports 1:1-1:5 instance_id
2 internalCost auto priority 16
Command : config stp mst_config_id ports 1:1-1:5 instance_id 2
internalCost auto priority 16
Success.
