To display the Smartports window, either
- Click
Smartports on the toolbar.
- Choose Configuration > Smartports.
The Smartports window provides options to automatically enable
Cisco-recommended configurations for the switch and for connections
from the switch ports. By using these Smartports options, some advanced
features are configured accurately, consistently, and quickly on
your switch and switch ports:
To save any changes that you make on this window, click Submit.
To discard any unsaved changes, click Cancel.
For complete information about the Smartports feature, see the
switch software configuration guide. The Support
window provides a link to the switch documentation.
The recommended system setup enables a set of
advanced system settings that can improve the performance of
the switch.
Check Enable to enable the recommended system
setup, and click Submit. To disable this feature,
uncheck Enable, and click Submit.
As a result of enabling the recommended system setup, these advanced
system settings are automatically enabled:
- Rapid Per-VLAN spanning-tree plus (PVST+) for load-balancing
across VLANs and providing rapid convergence of spanning-tree
instances
- Loop guard for preventing alternate or root ports from becoming
designated ports
- Dynamic port error recovery for link state failures
- Class of service (CoS)-to-Differentiated Services Code Point
(DSCP) mappings for high-performance quality of service
- UniDirectional Link Detection (UDLD) aggressive mode for detecting
and disabling unidirectional links on fiber-optic interfaces
These advanced settings cannot be changed through the device manager,
however they can be changed through
Network
Assistant or through the switch command-line interface (CLI).
For information about these features, see the switch configuration
guide. The Support
window provides a link to the switch documentation.
The recommended port setup options enable advanced connection settings
that can improve the performance of the connections between the
switch ports and attached devices. The advanced connection settings,
enabled through the port setup options, cannot be changed through
the device manager, however they can be changed through
Network
Assistant or through the switch command-line interface (CLI).
For information about these features, see the switch configuration
guide. The Support
window provides a link to the switch documentation.
You can enable a port setup on one
or more switch ports and assign
the enabled ports to specific VLANs.
Move the pointer over a port to display its port number and VLAN
ID (VLAN membership). If a port setup is enabled on the port, the
port setup name is also displayed.
Notes:
- When you enable a port setup on a port, all exising port settings
are removed.
- We recommend that you do not change specific port settings after
enabling a port setup on a port. Any port setting changes might
affect the effectiveness of the enabled port setup.
- Do not enable the desktop port setup on ports that are connected
to routers or to other switches.
The switch provides these port setup options:
 |
Use this port setup on a switch port that is
connected to a desktop device, such as a PC or printer. This
port setup increases network security and reliability on the
connection.
Note: Do not enable the desktop port setup
on ports that are connected to routers or to other switches.
|
 |
Use this port setup on a switch port that is connected
to another Cisco switch.
|
 |
Use this port setup on a switch port that is connected
to a Cisco router.
|
 |
Use this port setup on a switch port that is connected
to a Cisco IP phone. This port setup provides the same advanced
settings as the Desktop port setup, as well as dedicated voice
VLANs to ensure proper treatment of delay-sensitive voice
traffic.
|
 |
Use this port setup on a switch port that is connected
to a Cisco wireless access point.
Note: This port setup is available only on
the Cisco IOS Release 12.2 switch software image.
|
 |
No port setup is enabled on the switch. This is the factory
default. |
 |
A non-Cisco port setup or multiple port setups are enabled
on the port.
Note: Ports with the Unsupported Setup
icon are not displayed on the Customize
window. |
To enable a port setup on a specific port:
- Select a port setup option from the Select a port setup
list.
- Click the port. The icon for the selected port setup appears
on the port.
- Click Submit to enable the port setup on the
port.
To remove the port setup from a port:
- Select None from the Select a port
setup list.
- Click the port. The None icon appears on the port.
- Click Submit.
Notes:
- When you enable a port setup on a port, all exising port settings
are removed.
- We recommend that you do not change specific port settings after
enabling a port setup on a port. Any port setting changes might
affect the effectiveness of the port setup.
- Do not enable the desktop port setup on ports that are connected
to routers or to other switches.
To enable the selected port setup for all ports:
- Select a port setup option from the Select a port setup
list.
- Check Enable the selected port setup for all ports.
The icon for the selected port setup appears on the ports.
- For any port that should not be enabled with the selected port
setup:
- Select another port setup option from the Select
a port setup list.
- Click the port. The icon for the selected port setup appears
on the port.
- Click Submit.
To disable port setup for all ports:
- Select None from the Select a port
setup list.
- Check Enable the selected port setup for all ports.
The None icon appears on the ports.
- Click Submit.
Notes:
When you enable a port setup on a port, all exising port settings
are removed.
We recommend that you do not change specific port settings after
enabling a port setup on a port. Any port setting changes might
affect the effectiveness of the port setup.
Do not enable the desktop port setup on ports that are connected
to routers or to other switches.
Ports enabled with a port setup are listed in the Customize window.
You can assign these ports to different VLANs (also referred to
as VLAN memberships).
A VLAN is a way to restrict specific data broadcasts to specific
logical workgroups. For example, information about employee salaries
can be sent only to devices belonging to a VLAN created for payroll-related
communications. Ports assigned to the same VLAN can share the same
data broadcasts and system resources. Communication between VLANs
require a Layer 3 device (such as a router or a Layer 3 switch).
Each VLAN has an ID. By default, all ports are assigned to VLAN
1. VLAN 1 is typically where unrestricted broadcast traffic appears.
For complete information about VLANs, see the switch software configuration
guide. The Support
window provides a link to the switch documentation.
You can sort the contents in each table column either by port number
or VLAN ID. To sort a table column, click the column heading.
To change the VLAN membership of switch ports enabled with a port
setup, follow these steps:
Step 1 |
Click Customize Port Setup
to display the Customize window.
Note: You can display the Customize window
only if you have enabled a port setup on at least one port. |
Step 2 |
From the Customize window, change the VLAN ID to which
the port belongs. The VLAN ID can be from 1 to 1001. The default
is 1.
See the switch software configuration guide for information
about using VLAN IDs from 1006 and higher.

Step 3 |
Click Done. |
Step 4 |
From the Smartports window, click Submit
to save your change. |
