About Auto SmartPorts

Auto SmartPort macros dynamically configure ports based on the device type detected on the port. When the switch detects a new device on a port, it applies the appropriate Auto SmartPorts macro. When a link-down event occurs on the port, the switch removes the macro. For example, when you connect a Cisco IP phone to a port, Auto SmartPorts automatically applies the Cisco IP phone macro. The Cisco IP phone macro enables quality of service (QoS), security features, and a dedicated voice VLAN to ensure proper treatment of delay-sensitive voice traffic.

Auto SmartPorts uses event triggers to map devices to macros. The most common event triggers are based on Cisco Discovery Protocol (CDP) messages received from connected devices. The detection of a device (Cisco IP phone, Cisco wireless access point, Cisco switch, or Cisco router) invokes an event trigger for that device.

Link Layer Discovery Protocol (LLDP) is used to detect devices that do not support CDP. Other mechanisms used as event triggers include the 802.1X authentication result and MAC-address learned.

System built-in event triggers exist for various devices based mostly on CDP and LLDP messages (Table 17-1) and some MAC address.and some MAC address. (Through Cisco IOS Release 12.2(54)SG, DMP is detected using the MAC address. Starting with Cisco IOS Release 15.0(2)SG, DMP is also detected using CDP.) These triggers are enabled as long as Auto SmartPort is enabled.

You can also define your own trigger. User-defined triggers can be CDP/LLDP-based, a group of MAC addresses, or the value of the attribute-value (AV) pair for the auto-smart-port keyword.

The Auto SmartPort macros are groups of CLI commands. Detection of devices on a port triggers the application of the macro for the device. (For example, detecting a CISCO_PHONE event on a port triggers the switch to apply the commands in the CISCO_PHONE_AUTO_SMARTPORT macro.) System built-in macros exist for various devices, and, by default, system built-in triggers are mapped to the corresponding built-in macros. You can change the mapping of built-in triggers or macros as needed.

A macro basically applies or removes a set of CLIs on an interface based on the link status. In a macro, the link status is checked. If the link is up, then a set of CLIs is applied; if the link is down, the set is removed (the no format of the CLIs are applied). The part of the macro that applies the set of CLIs is termed macro. The part that removes the CLIs (the no format of the CLIs) are termed antimacro.

Besides creating user-defined triggers, you can also create user-defined macros and map one to the other among all triggers (both built-in and user-defined) and all macros (both built-in and user-defined). Use the Cisco IOS scripting capability to create the macros. Cisco IOS scripting is a BASH-like language syntax for command automation and variable replacement.

The four detection mechanisms adhere to the following order of priority:

If 802.1X authentication is configured on a port, an authentication response-based trigger is applied, and other triggers are ignored.

If 802.1X authentication fails and the CDP/LLDP fallback mechanism is configured, CDP/LLDP triggers for phone devices only; if no fallback mechanism is configured, or a device is not a phone device, nothing is triggered.

If 802.1X authentication is configured on a port, a MAC address-based trigger is never triggered.

If 802.1X authentication is not configured on a port, CDP/LLDP has priority over a MAC address-based trigger with a hold-off timer applied for MAC-address based trigger. Between CDP/LLDP, there is no particular order; whichever one arrives first is triggered.

Enabling Auto SmartPorts


Note By default, Auto SmartPort is disabled globally. To disable Auto SmartPorts macros on a specific port, use the no macro auto global processing interface command before enabling Auto SmartPort globally.


To enable Auto SmartPort globally, use the macro auto global processing global configuration command.

To enable Auto SmartPorts, perform this task:

 
Command
Purpose

Step 1 

Switch# configure terminal

Enters global configuration mode.

Step 2 

Switch(config)# [no] macro auto 
global processing [cdp | lldp]

Enables Auto SmartPorts on the switch globally.

Note Starting with Release 15.0(2)SG, the fallback option has been deprecated.

Use no macro auto global processing to disable Auto SmartPort globally.

Note The macro auto processing command turns Auto SmartPort on or off on the interface level. The default is on.

Step 3 

Switch(config)# end

Returns to privileged EXEC mode.

Step 4 

Switch# show running-config

Verifies that Auto SmartPorts is enabled.

Step 5 

Switch# copy running-config 
startup-config

(Optional) Saves your entries in the configuration file.

Use the show shell functions and the show shell triggers privileged EXEC command to display the event triggers, the built-in macros, and the built-in macro default values.

This example shows how enable Auto SmartPorts on the switch and how to disable the feature on a specific interface:

Switch(config)# macro auto global processing
Switch(config)# interface interface_id
Switch(config-if)# no macro auto processing

Auto SmartPorts Default Configuration

By default, Cisco IOS shell is enabled and Auto SmartPorts is disabled globally.

CISCO_DMP_AUTOSMARTPORT

Use this macro for a Cisco digital media player device. It enables QoS, port security, and access VLAN on the port.



Note By default, the built-in event triggers are mapped to the built-in macros.


Auto SmartPorts Configuration Guidelines

Auto SmartPort guidelines include the following:

To avoid system conflicts when Auto SmartPorts macros are applied, remove all port configuration except for 802.1X authentication.

If the macro conflicts with the original configuration, some macro commands might not be applied, or some antimacro commands might not be applied. (The antimacro is the portion of the applied macro that removes it at link down.)


Note Failure of one command in the macro halts the application of the entire macro.


For example, if 802.1X authentication is enabled, you cannot remove switchport-mode access configuration. You must remove the 802.1X authentication before removing the configuration.

A port should not be a member of an EtherChannel when applying Auto SmartPorts macros.

If Auto SmartPort is not yet enabled globally, disable Auto SmartPort on all the EtherChannel ports before enabling it globally. If Auto SmartPort is already enabled, shut down the port and disable it before adding the port to an EtherChannel.


Note If an Auto SmartPort macro is applied on an interface, EtherChannel configuration usually fails because of conflict with the auto-QoS configuration applied by the macro.


The built-in macro default data VLAN is VLAN 1. The default voice VLAN is VLAN 2. You should modify the built-in macro default values if your switch uses different VLANs. To view all built-in macro default values, use the show shell functions privileged EXEC command.

To detect non-Cisco devices for 802.1X authentication or MAB, configure the RADIUS server to support the Cisco AV pair auto-smart-port=event trigger. You must configure a user-defined trigger with the value returned in the AV pair for auto-smart-port.

For stationary devices that do not support CDP, MAB, or 802.1X authentication, such as network printers, we recommend that you disable Auto SmartPorts on the port.

If authentication is enabled on a port, the switch ignores CDP unless the fallback cdp keyword is in the macro auto global processing global configuration command.

The order of CLI commands within the macro and the corresponding antimacro can differ.

Before converting a port into an Layer 3 interface, enter the no macro auto processing command. This prevents Auto SmartPort from applying macros on the interface. If Layer 3 is already configured, enter the no macro auto processing command on the Layer 3 interface enable Auto SmartPort globally.

Auto SmartPort and SmartPorts cannot coexist on an interface.

A switch applies a macro in accordance with the LLDP advertisement from the attached device. If the device does not identify itself properly, the wrong macro is applied. Consult the specific device documentation to ensure the device's firmware is current.

The LWAP's WLC software version must be 6.0.188 ( => Cisco IOS 12.4(21a)JA2) or later to make it detectable as LWAP by AutoSmartPort.

As of Cisco IOS Release 12.2(54)SG, Auto SmartPort does not support macros that apply EtherChannel configurations. Interfaces that belong to EtherChannel groups are treated as standard interfaces. You can apply macros on individual interfaces based on the device type but the CLIs in the macro (for example, auto-QoS) might conflict with an EtherChannel configuration. We recommend that you disable Auto SmartPort on interfaces belonging to EtherChannels before you enable Auto SmartPort globally. If Auto SmartPort is already enabled, disable Auto SmartPort on the interfaces before configuring EtherChannel.

Configuring Auto SmartPorts Built-in Macro Parameters

The switch automatically maps from built-in event triggers to built-in macros. You can replace the built-in macro default values with values that are specific to your switch.

To configure Auto SmartPorts built-in macros parameters, perform this task:

 
Command
Purpose

Step 1 

Switch# configure terminal

Enters global configuration mode.

Step 2 

Switch(config)# macro auto execute 
event trigger builtin built-in 
macro name [parameter=value] 
[parameter=value]

Defines mapping from an event trigger to a built-in macro.

Specify an event trigger value:

CISCO_PHONE_EVENT

CISCO_SWITCH_EVENT

CISCO_ROUTER_EVENT

CISCO_WIRELESS_AP_EVENT

CISCO_WIRELESS_LIGHTWEIGHT_AP_EVENT

CISCO_DMP_EVENT

CISCO_IPVSC_EVENT

WORD—Apply a user-defined event trigger.

Specify a built-in macro name value:

CISCO_PHONE_AUTO_SMARTPORT
(Optional) Specify the parameter values: $ACCESS_VLAN=(1) and $VOICE_VLAN=(2).

CISCO_SWITCH_AUTO_SMARTPORT
(Optional) Specify the parameter values: $NATIVE_VLAN=(1).

CISCO_ROUTER_AUTO_SMARTPORT
(Optional) Specify the parameter values: $NATIVE_VLAN=(1).

CISCO_AP_AUTO_SMARTPORT
(Optional) Specify the parameter values: $NATIVE_VLAN=(1).

CISCO_LWAP_AUTO_SMARTPORT
(Optional) Specify the parameter values: $ACCESS_VLAN=(1).

CISCO_DMP_AUTO_SMARTPORT

CISCO_IP_CAMERA_AUTO_SMARTPORT

(Optional) parameter=value—Replace default values that begin with $. Enter new values in the form of name value pair separated by a space: [name1=value1 name2=value2...]. Default values are shown in parenthesis.

Step 3 

Switch(config)# end

Returns to privileged EXEC mode.

Step 4 

Switch# show running-config

Verifies your entries.

Step 5 

Switch# copy running-config 
startup-config

(Optional) Saves your entries in the configuration file.

The no macro auto execute event trigger {[builtin built-in macro name [parameter=value]] | [[parameter=value] {function contents}]} command deletes the mapping.

This example shows how to use two built-in Auto SmartPorts macros for connecting Cisco switches and Cisco IP phones to the switch. This example modifies the default voice VLAN, access VLAN, and native VLAN for the trunk interface:

Switch# configure terminal
Switch(config)# macro auto execute CISCO_PHONE_EVENT builtin CISCO_PHONE_AUTO_SMARTPORT 
ACCESS_VLAN=10 VOICE_VLAN=20
Switch(config)#
Switch(config)#
Switch(config)#!!! the next command enables auto smart ports globally
Switch(config)# macro auto global processing fallback cdp
Switch(config)#
Switch(config)# exit
 
Switch#
Switch# show running-config interface gigabitethernet2/7

macro description CISCO_PHONE_EVENT
spanning-tree portfast

service-policy input AutoQos-VoIP-Input-Cos-Policy
service-policy output AutoQos-VoIP-Output-Policy
end

Note You can also use the macro auto device command to simplify changing the parameters for a built-in functions for a device type.


Configuring User-Defined Event Triggers

You can configure two types of event triggers: user-defined and MAC address-based.

The following sections describe these triggers:

802.1X-Based Event Trigger

MAC Address-Based Event Trigger

802.1X-Based Event Trigger

When using MAB or 802.1X authentication to trigger Auto SmartPorts macros, you need to create an event trigger that corresponds to the Cisco AV pair (auto-smart-port=event trigger) sent by the RADIUS server.

To configure an event trigger, perform this task:

 
Command
Purpose

Step 1 

Switch# configure terminal

Enters global configuration mode.

Step 2 

Switch(config)# shell trigger 
identifier description

Specifies the event trigger identifier and description.

The identifier should have no spaces or hyphens between words.

Step 3 

Switch(config)# end

Returns to privileged EXEC mode.

Step 4 

Switch# show shell triggers

Displays the event triggers on the switch.

Step 5 

Switch# copy running-config 
startup-config

(Optional) Saves your entries in the configuration file.

Use the no shell trigger identifier global configuration command to delete the event trigger.

The following example shows how to define a user-defined trigger:

Switch# configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Switch(config)# shell trigger RADIUS_MAB_EVENT MAC_AuthBypass Event 
Switch(config)#

MAC Address-Based Event Trigger

To configure a MAC address group as an event trigger, perform this task:

 
Command
Purpose

Step 1 

Switch# configure terminal

Enters global configuration mode.

Step 2 

Switch(config)# macro auto 
mac-address group

Specifies a group of MAC address as an event trigger.

Changes mode to config-mac-addr-grp. You can then add or remove the MAC address or Organizational Unique Identifier (OUI) from the group.

The group value defines the user-defined trigger.

Step 3 

Switch(config)# end 

Returns to privileged EXEC mode.

Step 4 

Switch# show shell triggers

Displays the event triggers on the switch.

Step 5 

Switch# copy running-config 
startup-config

(Optional) Saves your entries in the configuration file.

Use the no macro auto mac-address-group grp_name to delete the event trigger.

Configuring Mapping Between User-Defined Triggers and Built-in Macros

You need to map the user-defined trigger to either a built-in macro or user-defined macro.

To map a user-defined trigger to a built-in macros, perform this task:

 
Command
Purpose

Step 1 

Switch# configure terminal

Enters global configuration mode.

Step 2 

Switch(config)# macro auto execute 
event trigger builtin built-in macro 
name [parameter=value] 
[parameter=value]

Specifies a user-defined event trigger and a macro name. This action replaces built-in macro default values, and configures mapping from an event trigger to a built-in Auto Smartports macro.

Note When performing a mapping, you must provide parameter values. For example, you must specify $ACCESS_VLAN=(1) and $VOICE_VLAN=(2) for the macro CISCO_PHONE_AUTO_SMARTPORT.

Step 3 

Switch(config)# end 

Returns to privileged EXEC mode.

Step 4 

Switch# show shell triggers

Displays the event triggers on the switch.

Step 5 

Switch# copy running-config 
startup-config

(Optional) Saves your entries in the configuration file.

This example shows how to map a user-defined event trigger called RADIUS_MAB_EVENT to the built-in macro CISCO_PHONE_AUTO_SMARTPORT with access VLAN set to 10, and how to verify the entries.

This procedure shows how to map a user-defined trigger to a built-in macro:


Step 1 Connect the device to a MAB-enabled switch port.

Step 2 On the RADIUS server, set the attribute-value pair to auto-smart-port=RADIUS_MAB_EVENT.

Step 3 On the switch, create the event trigger RADIUS_MAB_EVENT.

The switch recognizes the attribute-value pair=RADIUS_MAB_EVENT response from the RADIUS server and applies the macro CISCO_PHONE_AUTO_SMARTPORT, as in the following example:

Switch(config)# macro auto execute RADIUS_MAB_EVENT builtin CISCO_PHONE_AUTO_SMARTPORT 
ACCESS_VLAN=10
Switch(config)# exit
Switch# show shell triggers 
User defined triggers

<output truncated>

Configuring Auto SmartPorts User-Defined Macros

The Cisco IOS shell provides basic scripting capabilities for configuring the user-defined Auto SmartPorts macros. These macros can contain multiple lines and can include any CLI command. You can also define variable substitution, conditionals, functions, and triggers within the macro.

Inside a user-defined macro, besides parameters specified through macro auto execute trigger parameter-name=value .., you also can use the following variables published by EEM (Table 17-3):

Table 17-3 Variables Published by EEM 

Parameter Name
Meaning

$INTERFACE

Name of the interface where the trigger event is detected.

$LINKUP

Indicates whether the interface is up or down (true/false).

$TRIGGER

Name of the trigger event that is raised (for example, CISCO_PHONE_EVENT).

$AUTH_ENABLED

Indicates whether 802.1X authentication is configured on the interface (true/false).


To map an event trigger to a user-defined macro, perform this task:

 
Command
Purpose

Step 1 

Switch# configure terminal

Enters global configuration mode.

Step 2 

Switch(config)# macro auto 
execute event trigger 
[parameter=value] {function 
contents}

Specifies a user-defined macro that maps to an event trigger.

Specify an event trigger value:

CISCO_PHONE_EVENT

CISCO_SWITCH_EVENT

CISCO_ROUTER_EVENT

CISCO_WIRELESS_AP_EVENT

CISCO_WIRELESS_LIGHTWEIGHT_AP_EVENT

WORD Applies a user-defined event trigger.

CISCO_DMP_EVENT

CISCO_IPVSC_EVENT

function contentsSpecifies a user-defined macro to associate with the trigger. Enter the macro contents within braces. Begin the Cisco IOS shell commands with the left brace and end the command grouping with the right brace.

(Optional) parameter=value—Replaces default values that begin with $, enter new values in the form of name value pair separated by a space: [name1=value1 name2=value2...].

Step 3 

Switch(config)# end

Returns to privileged EXEC mode.

Step 4 

Switch# show running-config

Verifies your entries.

Step 5 

Switch# copy running-config 
startup-config

(Optional) Saves your entries in the configuration file.

This example shows how to map a user-defined event trigger called Cisco Digital Media Player (DMP) to a user-defined macro.


Step 1 Connect the DMP to an 802.1X- or MAB-enabled switch port.

Step 2 On the RADIUS server, set the attribute-value pair to auto-smart-port =MY_MEDIAPLAYER_EVENT.

Step 3 On the switch, create the event trigger CISCO_DMP_EVENT, and map it to the user-defined macro commands shown below.

The switch recognizes the attribute-value pair=CISCO_DMP_EVENT response from the RADIUS server and applies the macro associated with this event trigger.

The following example shows the macro portion of the automacro:

Switch(config)# shell trigger CISCO_DMP_EVENT Cisco DMP player
Switch(config)# macro auto execute CISCO_DMP_EVENT { 
if [[ $LINKUP -eq YES ]]; then 
conf t 
 interface $INTERFACE 
   macro description $TRIGGER 
   switchport access vlan 1 
   switchport mode access 
   switchport port-security 
   switchport port-security maximum 1 
   switchport port-security violation restrict 
   switchport port-security aging time 2 
   switchport port-security aging type inactivity 
   spanning-tree portfast 
   spanning-tree bpduguard enable 
   exit 
fi 
 
   

The following represents the anti-macro portion of the automacro:

if [[ $LINKUP -eq NO ]]; then 
conf t 
interface $INTERFACE 
     no macro description $TRIGGER 
     no switchport access vlan 1 
     if [[ $AUTH_ENABLED -eq NO ]]; then 
        no switchport mode access 
     fi 
     no switchport port-security 
     no switchport port-security maximum 1 
     no switchport port-security violation restrict 
     no switchport port-security aging time 2 
     no switchport port-security aging type inactivity 
     no spanning-tree portfast 
     no spanning-tree bpduguard enable 
     exit 
fi
}
Switch(config)# end
