Defining Rapid STP Parameters Using CLI Commands
The following table summarizes the equivalent CLI commands for defining RSTP
parameters as displayed in the Rapid Spanning Tree (RSTP) page.
The following is an example of the CLI commands:
Console(config)# interface ethernet 1/e5
Console(config-if)# spanning-tree link-type shared
Configuring VLANs
VLANs are logical subgroups of a Local Area Network (LAN) created by software rather
than by defining a hardware solution. VLANs combine user stations and network devices
into a single domain regardless of the physical LAN segment to which they are attached.
VLANs allow network traffic to flow more efficiently within subgroups. VLANs managed
through software reduce the amount of time in which network changes are implemented.
VLANs are software-based and not defined by physical attributes. As a result, VLANs have
an unlimited number of ports and can be created per unit, per device, per stack, or any
other logical connection combination.
CLI Command Description
spanning-tree link-type {point-to-
point | shared}
Overrides the default link-type setting,
which is determined by the port duplex
mode, and enables the Rapid Spanning-
Tree Protocol (RSTP) transitions to the
forwarding state.
spanning tree mode {stp |rstp} Configures the RSTP currently running.
clear spanning-tree detected-
protocols
Restarts the protocol migration process.
show spanning-tree [ethernet
interface | port-channel port-
channel-number]
Displays RSTP configuration.
