To display the Smartports window, either • Click
• Choose Configure > Smartports. The Smartports window provides options (referred to as port roles) to automatically enable Cisco-recommended configurations for the switch and for connections from the switch ports. By using port roles, some advanced features are configured accurately, consistently, and quickly on your switch and switch ports: To save any changes that you make on this window, click Submit. To discard any unsaved changes, click Cancel. For complete information about the Smartports feature, see the switch software configuration guide. The Support window provides a link to the switch documentation. The recommended system setup enables a set of advanced system settings that can improve the performance of the switch. Check Enable to enable the recommended system setup, and click Submit. To disable this feature, uncheck Enable, and click Submit. 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 configuration guide. The Support window provides a link to the switch documentation. The recommended port setup options (or port roles) enable advanced connection settings that can improve the performance of the connections between the switch ports and attached devices. The advanced connection settings, enabled through the port roles, 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 configuration guide. The Support window provides a link to the switch documentation. You can enable a port role on one or more switch ports and assign the enabled ports to specific VLANs. Move the pointer over a port to display its port number and VLAN ID (VLAN membership). If a port role is enabled on the port, the port role name is also displayed. Important notes to remember: • When you enable a port role on a port, all existing port settings are removed. • We recommend that you do not change specific port settings after enabling a port role on a port. Any port setting changes might affect the effectiveness of the enabled port role. • Do not enable the desktop port role on ports that are connected to routers or to other switches. • Only the external switch ports support port roles. The switch provides these port roles:
Enabling and Disabling a Port Role on A Single Port To enable a port role on a specific port: 1. Select a port role from the Select a port role list. 2. Click the port. The icon for the selected port role appears on the port. 3. Click Submit to enable the port role on the port. To remove the port role from a port: 1. Select None from the Select a port role list. 2. Click the port. The None icon appears on the port. 3. Click Submit. Important notes to remember: • When you enable a port role on a port, all existing port settings are removed. • We recommend that you do not change specific port settings after enabling a port role on a port. Any port setting changes might affect the effectiveness of the port role. • Do not enable the desktop port role on ports that are connected to routers or to other switches. • Only the external switch ports support port roles. Enabling and Disabling a Port Role on All Ports To enable the selected port role on all ports: 1. Select a port role from the Select a port role list. 2. Check Enable the selected port role for all ports. The icon for the selected port role appears on the ports. 3. For any port that should not be enabled with the selected port role: a. Select another port role from the Select a port role list. b. Click the port. The icon for the selected port role appears on the port. 3. Click Submit. To disable port roles on all ports: 1. Select None from the Select a port role list. 2. Check Enable the selected port role for all ports. The None icon appears on the ports. 3. Click Submit. Important notes to remember: • When you enable a port role on a port, all existing port settings are removed. • We recommend that you do not change specific port settings after enabling a port role on a port. Any port setting changes might affect the effectiveness of the port role. • Do not enable the desktop port role on ports that are connected to routers or to other switches. • Only the external switch ports support port roles. Customizing the Port Role on Ports Ports enabled with a port role are listed in the Customize window. You can assign these ports to different VLANs (also referred to as VLAN memberships). A VLAN is a way to restrict specific data broadcasts to specific logical workgroups. For example, information about employee salaries can be sent only to devices belonging to a VLAN created for payroll-related communications. Ports assigned to the same VLAN can share the same data broadcasts and system resources. Communication between VLANs require a Layer 3 device (such as a router or a Layer 3 switch). Each VLAN has an ID. By default, all ports are assigned to VLAN 1. VLAN 1 is typically where unrestricted broadcast traffic appears. For complete information about VLANs, see the switch software configuration guide. The Support window provides a link to the switch documentation. You can sort the contents in each table column either by port number or VLAN ID. To sort a table column, click the column heading. To change the VLAN membership of switch ports enabled with a port role, follow these steps: 1. Click Customize to display the Customize window. Note that you can display the Customize window only if you have enabled a port role on at least one port. 2. From the Customize window, change the VLAN ID to which the port belongs. The VLAN ID can be from 1 to 1001. The default is 1. See the switch software configuration guide for information about using VLAN IDs from 1006 and higher. 3. Click Done. 4. From the Smartports window, click Submit to save your change. |
