DESCRIPTION
You can use the stp component to configure an STP instance.
EXAMPLES
list stp
Displays all STP instances on the system.
show running-config stp
Displays the running configuration information for all STP instances.
delete stp myStp2
Removes all members from the STP instance, and then deletes the instance itself.
Note that you cannot delete spanning tree instance 0 (the Common and Internal Spanning Tree). You can only use the
command delete in Multiple Spanning Tree Protocol (MSTP) mode.
OPTIONS
app-service
Specifies the name of the application service to which the object belongs. The default value is none. Note: If the
strict-updates option is enabled on the application service that owns the object, you cannot modify or delete the
object. Only the application service can modify or delete the object.
description
User defined description.
external-path-cost
Specifies the external path cost number for either an interface or trunk. The default value is 20000.
Each network interface has an associated path cost within each spanning tree instance. The path cost represents the
relative cost of sending network traffic through that interface. In calculating the spanning tree, the algorithm tries
to minimize the total path cost between each point of the tree and the root bridge. By manipulating the path costs of
different interfaces or trunks it is possible to steer traffic toward paths that are faster, more reliable, and/or
more economical. Path costs can take values in the range 1 - 200,000,000. The default path cost for an interface or a
trunk is based on the maximum, not actual speed, of the interface or trunk.
In MSTP mode there are two kinds of path cost: external and internal. The external path cost applies only to spanning
tree instance 0, the Common and Internal Spanning Tree (CIST). It is used to calculate the cost to reach an adjacent
spanning tree region.
glob Displays the items that match the glob expression. See help glob for a description of glob expression syntax.
instance-id
The instance ID for this STP instance. In Multiple Spanning Tree Protocol (MSTP) mode, there will be exactly one STP
instance with ID 0. The instance ID can be a value between 1 and 255.
internal-path-cost
Specifies the internal path cost number for either an interface or trunk. The default value is 20000.
Each network interface has an associated path cost within each spanning tree instance. The path cost represents the
relative cost of sending network traffic through that interface. In calculating the spanning tree, the algorithm tries
to minimize the total path cost between each point of the tree and the root bridge. By manipulating the path costs of
different interfaces or trunks it is possible to steer traffic toward paths that are faster, more reliable, and/or
more economical. Path costs can take values in the range 1 - 200,000,000. The default path cost for an interface or a
trunk is based on the maximum, not actual speed, of the interface or trunk.
In MSTP mode there are two kinds of path cost: external and internal. The internal path costs can be independently set
for each spanning tree instance (including instance 0) in MSTP mode. The internal path costs are used to calculate the
costs of reaching adjacent bridges within the same spanning tree region.
priority
Specifies the priority number of either a bridge, interface, or trunk. The default value for a bridge is 61440. The
default value for both interfaces and trunks is 128.
Each bridge, interface, and trunk in a spanning tree instance has a priority value. The relative values of the
priorities control the topology of the spanning tree chosen by the protocol. The bridge with the lowest priority value
(numerically) will become the root of the spanning tree. Priority values vary from 0 - 61440 in steps of 4096.
regex
Displays the items that match the regular expression. The regular expression must be preceded by an at sign (@[regular
expression]) to indicate that the identifier is a regular expression. See help regex for a description of regular
expression syntax.
vlans
Specifies the VLANs that you want to add to, delete from, or replace-all-with for this STP instance.
