NOTEIf only the IP Phone and Host bits are set, then the Smartport type is 
ip_phone_desktop.
Multiple Devices Attached to the Port
The device derives the Smartport type of a connected device via the capabilities 
the device advertises in its CDP and/or LLDP packets.
If multiple devices are connected to the device through one interface, Auto 
Smartport considers each capability advertisement it receives through that 
interface in order to assign the correct Smartport type. The assignment is based 
on the following algorithm:
•If all devices on an interface advertise the same capability (there is no 
conflict) the matching Smartport type is applied to the interface.
•If one of the devices is a switch, the 
Switch Smartport type is used.
•If one of the devices is an AP, the Wireless Access Point Smartport type is 
used.
•If one of the devices is an IP phone and another device is a host, the 
ip_phone_desktop Smartport type is used.
•If one of the devices is an IP phone desktop and the other is an IP phone or 
host, the ip_phone_desktop Smartport type is used.
•In all other cases the default Smartport type is used.
For more information about LLDP/CDP refer to the Configuring LLDP and 
Configuring CDP sections, respectively.
Persistent Auto Smartport Interface
If the Persistent status of an interface is enabled, its Smartport type and the 
configuration that is already applied dynamically by Auto Smartport remains on 
the interface even after the attaching device ages out, the interface goes down, 
and the device is rebooted (assuming the configuration was saved). The 
Smartport type and the configuration of the interface are not changed unless Auto 
Smartport detects an attaching device with a different Smartport type. If the Reserved 12-16 Ignore LLDP Capabilities Mapping to Smartport Type (Continued)

Persistent status of an interface is disabled, the interface reverts to the default 
Smartport type when the attaching device to it ages out, the interface goes down, 
or the device is rebooted. Enabling Persistent status on an interface eliminates the 
device detection delay that otherwise occurs.
NOTEThe persistence of the Smartport types applied to the interfaces are effective 
between reboots only if the running configuration with the Smartport type applied 
at the interfaces is saved to the startup configuration file. 
Error Handling
When a smart port macro fails to apply to an interface, you can examine the point 
of the failure in the Interface Settings page and reset the port and reapply the 
macro after the error is corrected from the Interface Settings and Interface 
Settings Edit pages.
Default Configuration
Smartport is always available. By default, Auto Smartport is enabled by Auto 
Voice VLAN, relies on both CDP and LLDP to detect attaching devices Smartport 
type, and detects Smartport type IP phone, IP phone + Desktop, Switch, and 
Wireless Access Point.
See Voic e VL AN for a description of the voice factory defaults.
Relationships with Other Features and Backwards 
Compatibility
Auto Smartport is enabled by default and may be disabled. Telephony OUI cannot 
function concurrently with Auto Smartport, and Auto Voice VLAN. Auto Smartport 
must be disabled before enabling Telephony OUI.
NOTEWhen upgrading from a firmware version that does not support Auto Smartport to 
a firmware level that supports Auto Smartport, the Auto Voice VLAN is disabled 
after the upgrade. If Telephony OUI was enabled before the upgrade, then Auto 
Smartport is disabled after the upgrade, and Telephony OUI remains enabled.

Workflow3: To adjust Smar tpor t macro parameter defaults and/or bind a 
user-defined macro pair to a Smar tpor t type, perform the following 
steps:
Through this procedure you can accomplish the following:
•View the macro source.
•Change parameter defaults.
•Restore the parameter defaults to the factory settings.
•Bind a user-defined macro pair (a macro and its corresponding anti-macro) 
to a Smartport type.
1. Open the Smartport > Smartport Type Settings page. 
2. Select the Smartport Type. 
3. Click View Macro S ourc e to view the current Smartport macro that is 
associated with the selected Smartport Type.
4. Click Edit to open a new window in which you can bind user-defined macros to 
the selected Smartport type and/or modify the default values of the parameters 
in the macros bound to that Smartport type. These parameter default values are 
used when Auto Smartport applies the selected Smartport type (if applicable) 
to an inter face.
5. In the Edit page, modify the fields.
6. Click Apply to rerun the macro if the parameters were changed, or Restore 
Defaults to restore default parameter values to built-in macros if required.
Workflow4: To rerun a Smar tpor t macro after it has failed, perform the 
following steps:
STEP 1In the Interface Settings page, select an interface with Smartport type Unknown.
STEP  2Click Show Diagnostics to see the problem.
STEP  3Troubleshoot, then correct the problem. Consider the troubleshooting tip below.
STEP  4Click Edit . A new window appears in which you can click Reset to reset the 
interface.
STEP  5Return to the main page and reapply the macro using either Reapply (for devices 
that are not switches, routers or APs) or Reapply Smartport Macro (for switches, 
routers or APs) to run the Smartport Macro on the interface.

A second method of resetting single or multiple unknown interfaces is:
STEP 1In the Interface Settings page, select the Port Type equals to checkbox.
STEP  2Select Unknown and click Go.
STEP  3Click Reset All Unknown Smartports. Then reapply the macro as described above.
TIPThe reason that the macro failed might be a conflict with a configuration on the 
interface made prior to applying the macro (most often encountered with security 
and storm-control settings), a wrong port type, a typo or an incorrect command 
within the user-defined macro, or an invalid parameter setting. Parameters are 
checked for neither type nor boundary prior to the attempt to apply the macro, 
therefore, an incorrect or invalid input to a parameter value will almost assuredly 
cause failure when applying the macro.
Configuring Smartport Using The Web-based Interface
The Smartport feature is configured in the Smartport > Properties, Smartport 
Type Settings and Interface Settings pages. 
For Voice VLAN configuration, see Voic e VL AN.
For LLDP/CDP configuration, see the Configuring LLDP and Configuring CDP 
sections, respectively.
Smartport Properties
To configure the Smartport feature globally: 
STEP 1Click Smartport > Properties.
STEP  2Enter the parameters.
•Administrative Auto Smartport—Select to globally enable or disable Auto 
Smartport. The following options are available:
-Disable—Select to disable Auto Smartport on the device.
-Enable—Select to enable Auto Smartport on the device.

-Enable by Auto Voice VL AN—This enables Auto Smartport, but puts it in 
operation only when Auto Voice VLAN is also enabled and in operation.   
Enable by Auto Voice VLAN is the default.
•Operational Auto Smartport—Displays the Auto Smartport status.
•Auto Smartport Device Detection Method—Select whether incoming 
CDP, LLDP, or both types of packets are used to detect the Smartport type 
of the attaching device(s). At least one must be checked in order for Auto 
Smartport to identify devices.
•Operational CDP Status—Displays the operational status of CDP. Enable 
CDP if Auto Smartport is to detect the Smartport type based on CDP 
advertisement.
•Operational LLDP Status—Displays the operational status of LLDP. Enable 
LLDP if Auto Smartport is to detect the Smartport type based on LLDP/
LLDP-MED advertisement.
•Auto Smartport Device Detection—Select each type of device for which 
Auto Smartport can assign Smartport types to interfaces. If unchecked, Auto 
Smartport does not assign that Smartport type to any interface.
STEP  3Click Apply. This sets the global Smartport parameters on the device.
Smartport Type Settings
Use the Smartport Type Settings page to edit the Smartport Type settings and 
view the Macro Source.
By default, each Smartport type is associated with a pair of built-in Smartport 
macros. See Smartport Types for further information on macro versus anti-macro. 
Alternatively, you can associate your own pair of user-defined macros with 
customized configurations to a Smartport type.   User-defined macros can be 
prepared only through CLI.   You should refer to the CLI reference guide for details.
Built-in or user-defined macros can have parameters. The built-in macros have up 
to three parameters.
Editing these parameters for the Smartport types applied by Auto Smartport from 
the Smartport Type Settings page configures the default values for these 
parameters. These defaults are used by Auto Smartport.

NOTEChanges to Auto Smartport types cause the new settings to be applied to 
interfaces which have already been assigned that type by Auto Smartport. In this 
case, binding an invalid macro or setting an invalid default parameter value causes 
all ports of this Smartport type to become unknown. 
STEP 1Click Smartport > Smartport Type Settings.
STEP  2To view the Smartport macro associated with a Smartport type, select a 
Smartport type and click View Macro Source.
STEP  3To modify the parameters of a macro or assign a user-defined macro, select a 
Smartport type and click Edit.
STEP  4Enter the fields.
•Port Type—Select a Smartport type.
•Macro Name—Displays the name of the Smartport macro currently 
associated with the Smartport type.
•Macro Type—Select whether the pair of macro and anti-macro associated 
with this Smartport type is built-in or user-defined.
•User Defined Macro—If desired, select the user-defined macro that is to be 
associated with the selected Smartport type.   The macro must have already 
been paired with an anti-macro. 
Pairing of the two macros is done by name and is described in the 
Smartport Macro section.
•Macro Parameters—Displays the following fields for three parameters in the 
macro:
-Parameter Name—Name of parameter in macro.
-Parameter Value—Current value of parameter in macro. This can be 
changed here.
-Parameter Description—Description of parameter.
You can restore the default parameter values by clicking Restore Defaults.
STEP  5Click Apply to save the changes to the running configuration. If the Smartport 
macro and/or its parameter values associated with the Smartport type are 
modified, Auto Smartport automatically reapplies the macro to the interfaces 
currently assigned with the Smartport type by Auto Smartport.   Auto Smartport 
does not apply the changes to interfaces that were statically assigned a 
Smartport type.

NOTEThere is no method to validate macro parameters because they do not have a type 
association. Therefore, any entry is valid at this point. However, invalid parameter 
values may cause errors to occur when the Smartport type is assigned to an 
interface, applying the associated macro.
Smartport Interface Settings
Use the Interface Settings page to perform the following tasks:
•Statically apply a specific Smartport type to an interface with interface 
specific values for the macro parameters.
•Enable Auto Smartport on an interface.
•Diagnose a Smartport macro that failed upon application, and caused the 
Smartport type to become Unknown. 
•Reapply a Smartport macro after it fails for one of the following types of 
interfaces: switch, router and AP. It is expected that the necessary 
corrections have been made prior to clicking Reapply. See the workflow 
area in Common Smartport Tasks section for troubleshooting tips.
•Reapply a Smartport macro to an interface.   In some circumstances, you 
may want to reapply a Smartport macro so that the configuration at an 
interface is up to date.   For instance, reapplying a switch Smartport macro 
at a device interface makes the interface a member of the VLANs created 
since the last macro application.   You have to be familiar with the current 
configurations on the device and the definition of the macro to determine if 
a reapplication has any impact on the interface.
•Reset unknown interfaces. This sets the mode of Unknown interfaces to 
Default.
To apply a Smartport macro:
STEP 1Click Smartport > Interface Settings.
Reapply the associated Smartport macro in the following ways:
•Select a group of Smartport types (switches, routers or APs) and click 
Reapply Smartport Macro. The macros are applied to all selected 
interface types.
•Select an interface that is UP and click Reapply to reapply the last macro 
that was applied to the interface.

The Reapply action also adds the interface to all newly-created VLANs.
STEP  2Smartport Diagnostic.
If a Smartport macro fails, the Smartport Type of the interface is Unknown. Select 
an interface which is of unknown type and click Show Diagnostic. This displays 
the command at which application of the macro failed. See the workflow area in 
Common Smartport Tasks section for troubleshooting tips. Proceed to reapply 
the macro after correcting the problem.
STEP  3Resetting all Unknown interfaces to Default type. 
•Select the 
Por t Type equals to checkbox.
•Select 
Unknown and click Go.
•Click Reset All Unknown Smartports. Then reapply the macro as described 
above. This performs a reset on all interfaces with type Unknown, meaning 
that all interfaces are returned to the Default type. After correcting the error 
in the macro or on the current interface configuration or both, a new macro 
may be applied.
NOTEResetting the interface of unknown type does not reset the configuration 
performed by the macro that failed. This clean up must be done manually.
To assign a Smartport type to an interface or activate Auto Smartport on the 
interface:
STEP 1Select an interface and click Edit.
STEP  2Enter the fields. 
•Interface—Select the port or LAG.
•Smartport Type—Displays the Smartport type currently assigned to the 
port/LAG.
•Smartport Application—Select the Smartport type from the Smartport 
Application pull-down.
•Smartport Application Method— If Auto Smartport is selected, Auto 
Smartport automatically assigns the Smartport type based on the CDP and/
or LLDP advertisement received from the connecting devices as well as 
applying the corresponding Smartport macro. To statically assign a 
Smartport type and apply the corresponding Smartport macro to the 
interface, select the desired Smartport type.

•Persistent Status—Select to enable the Persistent status. If enabled, the 
association of a Smartport type to an interface remains even if the interface 
goes down, or the device is rebooted.   Persistent is applicable only if the 
Smartport Application of the interface is Auto Smartport. Enabling Persistent 
at an interface eliminates the device detection delay that otherwise occurs.
•Macro Parameters—Displays the following fields for up to three parameters 
in the macro:
-Parameter Name—Name of parameter in macro.
-Parameter Value—Current value of parameter in macro. This can be 
changed here.
-Parameter Description—Description of parameter.
STEP  3Click Reset to set an interface to Default if it is in Unknown status (as a result of an 
unsuccessful macro application). The macro can be reapplied on the main page.
STEP  4Click Apply to update the changes and assign the Smartport type to the interface.
Built-in Smartport Macros
The following describes the pair of built-in macros for each Smartport type. For 
each Smartport type there is a macro to configure the interface and an anti macro 
to remove the configuration.
Macro code for the following Smartport types are provided:
•desktop
•printer
•guest
•server
•host
•ip_camera
•ip_phone
•ip_phone_desktop
•switch
