xStack Gigabit Layer 3 Switch Command Line Interface Manual
config stp mst_ports
higher priority value for interfaces to be selected for forwarding
first. In instances where the priority value is identical, the MSTP
function will implement the lowest port number into the forwarding
state and other interfaces will be blocked. Remember that lower
priority values mean higher priorities for forwarding packets.
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.
