Back to the top ### What Is Smartports The Smartports feature is a set of Cisco-recommended configurations for the switch ports. These configurations (referred to as port roles) optimize the switch connections and ensure security and transmission quality for traffic from the switch ports. The port roles also prevent many problems caused by port misconfigurations. Tip: Use Smartports immediately after the initial setup. The ports are then correctly configured before they are connected to devices. The only prerequisite is to decide which switch port will be connected to which device type. Back to the top ### Smartports Roles The Smartports roles are based on the type of devices to be connected to the switch ports. For example, the IE Desktop port role is specifically for switch ports to be connected to desktop and laptop PCs. By default, the switch ports are set with the None port role. Note: A port role cannot be applied to a routed port. The switch provides these Smartports roles:
| Apply this role to ports to be connected to desktop devices, such as desktop PCs, workstations, notebook PCs, and other client-based hosts. Note: Do not apply to ports to be connected to switches, routers, or access points. Do not apply to ports to be connected to non-Cisco, non-desktop devices. This will disable the ports.
| Apply this role to ports to be connected to other switches.
| Apply this role to non-Gigabit ports to be connected to routers or Layer 3 switches with routing service capabilities. Use this role if the port will connect to devices that connect to the WAN or the Internet.
| Apply this role to ports to be connected to IP phones. A desktop device, such as a PC, can be connected to the IP phone. Both the IP phone and the connected PC would have network and Internet access through the switch port. This role ensures quality of service (QoS) to delay-sensitive voice traffic.
| Apply this role to ports to be connected to wireless access points. The access point can provide network access to up to 30 mobile (wireless) users.
| Apply this role to ports to be connected to Ethernet/IP (Ethernet Industrial Protocol) devices. This role can be used to manage industrial automation devices, such as logic controllers and I/O.
| Apply this role to a port to be connected to a network analyzer or other monitoring or security device. This role can be used to analyze network traffic being sent and received on the connected switch port. Assigning and unassigning this port role is available only through the device manager.
| Apply this role to ports if you do not want to apply a specialized Smartports role on the port. This role can be used on connections to guest or visitor devices, printers, desktops, and IP phones.
Back to the top ### Avoid Smartports Mismatches A Smartports mismatch is when an attached device does not match the Smartports role applied to the switch port. Mismatches can have adverse effects on devices and your network. For example, mismatches Affect the behavior of the attached device Reduce the level of QoS on voice, wireless, switch, and router traffic Reduce restrictions on guest access to the network Reduce protection from denial of service (DoS) attacks on the network Disable or shut down the port We recommend that you always verify which Smartports role is applied to a port before attaching a device to the port or reconnecting devices that have been moved. Back to the top ### Apply the Recommended System Setup The recommended system setup enables a set of advanced system settings that can improve the performance of the switch. Select Enable to enable the recommended system setup, and click Submit. To disable this feature, deselect Enable, and click Submit. Back to the Top #### Advanced System Settings As a result of enabling the recommended system setup, these advanced system settings are automatically enabled: 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 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 These advanced settings cannot be changed through the device manager, however they can be changed through Network Assistant or through the switch command-line interface (CLI). For information about these features, see the switch software configuration guide. The Support window provides a link to the switch documentation. Back to the top ### Apply a Smartports Role From the Smartports window, you can see which Smartports role is applied to each port. Move the pointer over a port to display its port number, Smartports role, and VLAN ID (VLAN membership). You can apply a Smartports role to a specific port or to all ports on the switch. Notes: When you apply a Smartports role on a port, all existing settings on the port are removed. We recommend that you do not change specific port settings after enabling a Smartports role on a port. Any port setting changes can alter the effectiveness of the Smartports role. Do not apply the IE Desktop port role on ports that are connected to routers or to other switches. Back to the top #### Apply a Smartports Role to a Single Port Choose a Smartports role from the Select a port role list. Click the port. The icon for the selected Smartports role appears on the port. Click Submit to save your changes. Back to the top #### Apply a Smartports Role to All Ports Choose a Smartports role from the Select a port role list. Select the Apply the selected port role to all ports check box. The icon for the selected Smartports role appears on the ports. Click Submit to save your changes. Back to the top #### Remove an Applied Smartports Role To remove the Smartports role applied to a port: Choose None from the Select a port role list. Click the port. The None icon appears on the port. Click Submit to save your changes. To remove the Smartports role applied to all ports: Choose None from the Select a port role list. Select the Apply the selected port role for all ports check box. The None icon appears on the ports. Click Submit to save your changes. Back to the top ### Customize the Smartports Configuration on the Ports Customizing (or refining) the Smartports configuration on a port involves changing VLAN memberships. Click Customize from the Smartports window to display these advanced settings. Note: Before changing VLAN memberships, you should understand what a VLAN is, its purpose, and how to create a VLAN. Back to the top #### Assign a Port to a VLAN (VLAN Memberships) Each switch port is a member of a VLAN. Devices attached to switch ports that belong to the same VLAN share the same data broadcasts and system resources. Communication between VLANs requires a Layer 3 device (such as a router or a Layer 3 switch). Depending on your network requirements, it might be sufficient to assign all ports to the default VLAN, which is named default. If additional VLANs have been created, you must decide which ports are best suited to which VLANs. To change a VLAN assignment: Click Customize from the Smartports window. Choose a VLAN for each port: For ports applied with the IE Switch, IE Router, or IE Wireless port role, choose a VLAN from the Native VLAN list. For ports applied with the Cisco EtherNet/IP, IE Desktop, IE IP Phone, or None port role, choose a VLAN from the Access VLAN list. For ports applied with the IE IP Phone port role, choose a VLAN from the Voice VLAN list. For ports applied with the Diagnostics port role, choose a VLAN from the Ingress VLAN list and chose the port to be monitored from the Source Interface list. Click Done.
