About Auto Smartport Macros

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 Smartport 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 Smartport 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 Smartport 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.
