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 desktop
connections from the switch ports. By using these Smartports options,
some advanced features will be 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, refer to the switch
software configuration guide.
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.
The advanced system settings enabled through Smartports are
- 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
- VLAN Trunking Protocol (VTP) transparent mode for reducing network
traffic by restricting flooded traffic to links destined for stations
receiving the traffic
- 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
For information about these features, refer to the switch configuration
guide.
The recommended desktop port setup enables a set of advanced
desktop connection settings that can increase network security and reliability
when a desktop device, such as a PC, is connected to a switch port.
Move the pointer over a port to display its port number and VLAN
ID (VLAN membership).
Click a port until the desktop icon appears, and click Submit
to enable the desktop port setup on a specific switch port.
To disable this feature, click the port until the desktop icon disappears,
and click Submit.
Check Enable the desktop port setup for all ports,
and click Submit to enable the desktop port setup
for all switch ports. To disable this feature for all ports, uncheck
Enable the desktop port setup for all ports, and
click Submit.
Note: Do not enable the desktop port setup on
ports that are connected to routers or to other switches.
The ports listed in the Customize window are enabled with the desktop
port setup. 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. 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, refer to the switch software
configuration guide.
To change the VLAN membership of switch ports enabled for desktop
connections, follow these steps:
Step 1 |
Click Customize Port Setup.
Note: You can display the Customize window
only if you have enabled the recommended desktop port setup
on at least one port. |
Step 2 |
From the Customize window, change the VLAN to which the
port belongs. The ID number can be from 1 to 1001 or from
1006 to 4094. The default is 1.
Note: You can use the VLAN ID numbers in
the 1006 to 4094 range only
if your switch is running the
enhanced software image (EI) and
if you have enabled the recommended
system setup on the switch.

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

The advanced switch-to-desktop connection settings enabled through
Smartports are
- Port security to limit the forwarding of packets by only two
devices
- Port-security aging to set the aging time for secure addresses
on a port
- Spanning-tree PortFast mode for eliminating the forwarding delay
on a port
- Spanning-tree bridge protocol data unit (BPDU) guard for shutting
down Port Fast-enabled ports that receive BPDUs
For information about these features, refer to the switch configuration
guide.
