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.
