Smartports Auto Smartport 10 • If a device is aged out (no longer receiving advertisements from other devices), the interface configuration is changed according to its Persistent Status. If the Persistent Status is enabled, the interface configuration is retained. If not, the Smartport Type reverts to Default. Enabling Auto Smartport Auto Smartport can be enabled globally in the Properties page in the following ways: • Enabled-This manually enables Auto Smartport and places it into operation immediately. • Enable by Auto Voice VLAN-This enables Auto Smartport to operate if Auto Voice VLAN is enabled and in operation. Enable by Auto Voice VLAN is the default. NOTE In addition to enabling Auto Smartport globally, you must enable Auto Smartport at the desired interface as well. By default, Auto Smartport is enabled at all the interfaces. See Voice VLAN for more information on enabling Auto Voice VLAN Identifying Smartport Type If Auto Smartport is globally enabled (in the Properties page), and at an interface (in the Interface Settings page), the switch applies a Smartport macro to the interface based on the Smartport type of the attaching device. Auto Smartport derives the Smartport types of attaching devices based on the CDP and/or LLDP the devices advertise. If, for example, an IP phone is attached to a port, it transmits CDP or LLDP packets that advertise its capabilities. After reception of these CDP and/or LLDP packets, the switch derives the appropriate Smartport type for phone and applies the corresponding Smartport macro to the interface where the IP phone attaches. Unless Persistent Auto Smartport is enabled on an interface, the Smartport type and resulting configuration applied by Auto Smartport is removed if the attaching device(s) ages out, links down, reboots, or conflicting capabilities are received. Aging out times are determined by the absence of CDP and/or LLDP advertisements from the device for a specified time period. Cisco Small Business 200 Series Smart Switch Administration Guide 126

Auto Smartport

Cisco Small Business 200 Series Smart Switch Administration Guide

126

•

If a device is aged out (no longer receiving advertisements from other

devices), the interface configuration is changed according to its Persistent

Status. If the Persistent Status is enabled, the interface configuration is

retained. If not, the Smartport Type reverts to Default.

Enabling Auto Smartport

Auto Smartport can be enabled globally in the

Properties

page in the following

ways:

•

Enabled

—This manually enables Auto Smartport and places it into

operation immediately.

•

Enable by Auto Voice VLAN

—This enables Auto Smartport to operate if

Auto Voice VLAN is enabled and in operation. Enable by Auto Voice VLAN is

the default.

NOTE

In addition to enabling Auto Smartport globally, you must enable Auto Smartport at

the desired interface as well. By default, Auto Smartport is enabled at all the

interfaces.

See

Voice VLAN

for more information on enabling Auto Voice VLAN

Identifying Smartport Type

If Auto Smartport is globally enabled (in the

Properties

page), and at an interface

(in the

Interface Settings

page), the switch applies a Smartport macro to the

interface based on the Smartport type of the attaching device. Auto Smartport

derives the Smartport types of attaching devices based on the CDP and/or LLDP

the devices advertise.

If, for example, an IP phone is attached to a port, it transmits CDP or LLDP packets

that advertise its capabilities. After reception of these CDP and/or LLDP packets,

the switch derives the appropriate Smartport type for phone and applies the

corresponding Smartport macro to the interface where the IP phone attaches.

Unless Persistent Auto Smartport is enabled on an interface, the Smartport type

and resulting configuration applied by Auto Smartport is removed if the attaching

device(s) ages out, links down, reboots, or conflicting capabilities are received.

Aging out times are determined by the absence of CDP and/or LLDP

advertisements from the device for a specified time period.
