xStack DGS-3400 Series Layer 2 Gigabit Managed Switch CLI Manual
Used to update the MSTP configuration identification.
config stp mst_config_id {revision_level <int 0-65535> | name
<string>}
This command will uniquely identify the MSTP configuration currently
configured on the Switch. Information entered here will be attached to
BPDU packets as an identifier for the MSTP region to which it belongs.
Switches having the same revision_level and name will be considered
as part of the same MSTP region.
revision_level <int 0-65535>– Enter a number between 0 and 65535 to
identify the MSTP region. This value, along with the name will identify
the MSTP region configured on the Switch. The default setting is 0.
name <string> - Enter an alphanumeric string of up to 32 characters to
uniquely identify the MSTP region on the Switch. This name, along with
the revision_level value will identify the MSTP region configured on the
Switch. If no name is entered, the default name will be the MAC address
of the device.
Only administrator-level users can issue this command.
Used to update the port configuration for a MSTP instance.
config stp mst_ports <portlist> instance_id <value 0-15>
{internalCost [auto | <value 1-20000000>] priority <value 0-240>}
This command will update the port configuration for a STP instance_id. If
a loop occurs, the MSTP function will use the port priority to select an
interface to put into the forwarding state. Set a 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.
<portlist> - Specifies a range of ports to be configured. The beginning
and end of the port list range are separated by a dash. For example, 1-4
specifies all of the ports between port 1 and port 4.
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
