Equipment that You Supply to Run Express Setup You need to supply this equipment to run Express Setup: • PC • Ethernet (Category 5) straight-through cable (as shown) 3 Running Express Setup When you first set up the switch, you should use Express Setup to enter the initial IP information. Doing this enables the switch to connect to local routers and the Internet. You can then access the switch through the IP address for further configuration.
Step 5 Press and hold the Mode button for 3 seconds. When all of the LEDs above the Mode button turn green, release the Mode button. If the LEDs above the Mode button begin to blink after you press the button, release it. Blinking LEDs mean that the switch has already been configured and cannot go into Express Setup mode. For more information, see the “Resetting the Switch” section on page 35.
Step 11 The Express Setup page appears. If it does not appear, see the “In Case of Difficulty” section on page 34 for help. Step 12 Enter this information in the Network Settings fields: • In the Management Interface (VLAN ID) field, the default is 1. Enter a new VLAN ID only if you want to change the management interface through which you manage the switch and to which you assign IP information. The VLAN ID range is 1 to 1001. • In the IP Address field, enter the IP address of the switch.
Step 13 In the Wireless Controller Settings area (see the Figure in Step 11), the stack number displays the stack-member number of the switch. Enter this information: • In the Management Interface (VLAN ID) field, the default is 0. Enter a new VLAN ID only if you want to change the management interface through which you manage the controller and to which you assign IP information. If you entered a VLAN ID other than 1 in Step 12, then enter the same VLAN ID for the controller.
Step 14 (Optional) You can enter the Optional Settings information now or enter it later by using the device manager interface: • In the Host Name field, enter a name for the switch. The host name is limited to 31 characters; embedded spaces are not allowed. • In the Telnet Access field, click Enable if you are going to use Telnet to manage the switch by using the command-line interface (CLI). If you enable Telnet access, you must enter a Telnet password. • In the Telnet Password field, enter a password.
Refreshing the PC IP Address After you complete Express Setup, you should refresh the PC IP address: • For a dynamically assigned IP address, disconnect the PC from the switch, and reconnect it to the network. The network DHCP server assigns a new IP address to the PC. • For a statically assigned IP address, change it to the previously configured IP address.
3. Download the Network Assistant installer, and run it. (You can run it directly from the Web if your browser offers this choice.) 4. When you run the installer, follow the displayed instructions. In the final panel, click Finish to complete the Network Assistant installation. Refer to the Network Assistant online help and the getting started guide for more information. Command-Line Interface You can enter Cisco IOS commands and parameters through the CLI.
5 Preparing the Wireless LAN Controller for Operation Follow these major steps to prepare the integrated wireless LAN controller for operation.
Step 4 Enter the management IP address of the switch (which you set in Step 12 of the Express Setup) in the web browser, and press Enter. The Catalyst 3750 Device Manager page appears. Step 5 Under Contents, click Controller Device Manager. Step 6 When prompted for a username and password, enter admin in each field. The first page of the Configuration Wizard appears.
Step 7 In the System Name field, enter the system name, which is the name that you want to assign to the controller. You can enter up to 32 ASCII characters. Step 8 In the User Name and Password fields, enter the administrative username and password for this controller. You can enter up to 24 ASCII characters for each. The default administrative username and password are both admin. Step 9 Click Next. The Service Interface Configuration page appears.
Step 12 Click Next. The Management Interface Configuration page appears. Step 13 Enter the VLAN identifier zero (0) if the VLAN ID set on the switch management interface is 1. If you entered a VLAN ID other than 1 on the switch management interface (see Step 12 of the Running Express Setup section), enter the same VLAN ID for the controller. Enter the IP address, the netmask, and the gateway for the management interface.
Step 15 Click Next. The Miscellaneous Configuration page appears.
Step 16 From the LWAPP Transport Mode drop-down box, choose Layer 3. The controller operates only in Layer 3 mode. Step 17 (Optional) In the RF Mobility Domain Name field, enter the name of the mobility group/ RF group to which you want the controller to belong. Although the name that you enter here is assigned to both the mobility group and the RF group, these groups are not identical. Both groups define clusters of controllers, but they have different purposes.
Step 21 Enter the IP addresses of the primary and the optional secondary DHCP servers that supply IP addresses to the controller AP-manager interface. If the AP-manager interface is on the same subnet as the management interface, the AP-manager interface uses the same DHCP server IP address as the management interface. Step 22 Click Next. The Virtual Interface Configuration page appears.
Step 25 Click Next. The WLAN Policy Configuration page appears. Step 26 In the WLAN SSID field, enter the network name or service set identifier (SSID). This is the default SSID that the access points use when they join a controller. Step 27 Under General Policies, check the DHCP Address Assignment Required check box to make clients request an IP address from a DHCP server, or uncheck this check box to allow clients to assign their own IP addresses.
Step 29 Click Next. The RADIUS Server Configuration page appears. Step 30 To configure a RADIUS server now, enter the IP address, the shared secret, and the communication port of the RADIUS server, and click Apply. Otherwise, click Skip. The IEEE 802.11 Configuration page appears. Step 31 Check or uncheck the 802.11a, 802.11b, and 802.11g Network Status check boxes to enable or disable each of the IEEE 802.11a, IEEE 802.11b, and IEEE 802.11g lightweight access point networks.
Step 32 Check or uncheck the Auto RF check box to enable or disable the controller radio resource management (RRM) auto-RF feature. The auto-RF feature enables the controller to automatically form an RF group with other controllers. The group dynamically elects a leader to optimize RRM parameter settings, such as channel and send power assignments, for the group. Step 33 Click Next. The Configuration Wizard Completed page appears. Step 34 Click Save and Reboot.
Verifying Interface Settings and Port Operation Follow these steps to verify that your interface configurations have been set properly and that the controller ports are operational. Step 1 Enter show interface summary, and press Enter. This display shows the controller interface configurations: Interface Name Port Vlan Id ------------------------------ ---- -------ap-manager LAG 10 management LAG 10 service-port N/A N/A virtual N/A N/A IP Address Type Ap Mgr -------------- ------- ----10.91.104.
Connecting Access Points After you have configured the controller, use Category-5, -5e, -6, or -7 Ethernet cables to connect Cisco lightweight access points to the network. As soon as the controller is operational, it starts to scan for access points. When it detects one, it records the its MAC address in its database. The controller RRM feature then automatically configures the access point to start sending and allowing clients to associate.
6 Planning Switch Stacks Before connecting the Catalyst 3750 switches in a stack, keep in mind these planning considerations: • The size of the switch—See the“Technical Specifications” appendix of the Catalyst 3750 Switch Hardware Installation Guide for the switch dimensions. Stacking together switches of the same size makes it easier to cable the switches. • Length of cable—Depending on the configuration of your switch stack, you might need different-sized cables.
Cabling Considerations These illustrations show the recommended Catalyst 3750 switch stack configurations with redundant StackWise cabling connections for optimized stack bandwidth. For more configuration examples, see the Catalyst 3750 Switch Hardware Installation Guide on Cisco.com.
