During Express Setup, VLAN 1 is the only VLAN on the switch. Enter a new VLAN ID only if you want to change the management interface through which youmanage the switch. The VLAN ID range is 1 to 1001.•In the IP Address field, enter the switch IP address.•In the Subnet Mask field, click the drop-down arrow, and select a subnet mask.•In the Default Gateway field, enter the IP address for the default gateway (router).•Enter your password in the Switch Password field. The password can be from 2 to 25 alphanumeric characters, can start with a number, is case sensitive, allows embedded spaces, but does not allow spaces at the beginningor end. In the Confirm Switch Password field, enter your password again.Note You must change the default password, cisco.(Optional) Enter this information in the Ethernet Management Port Settings fields:•In the IP Address field, enter the IP address of the Ethernet management port. In the Subnet Mask field, click the drop-down arrow, and select an IP Subnet Mask.Step10(Optional) You can enter the Optional Settings information now or enter it later by using the Device Manager interface.You can enter other administrative settings in the Optional Settings fields. For example, the optional administrative settings identify and synchronize the switch for enhanced management. NTP automatically synchronizes the switch clock with the network clock. You can manually set the system clock if the switch should have different settings. Step11(Optional) You can select the Advanced Settings tab on the Express Setup window and enter the advanced settings now or enter them later by using the Device Manager interface.•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.

The IPv6 field is enabled by default.Note Enabling IPv6 restarts the switch when you complete Express Setup.Catalyst 3850 Switch Getting Started GuideManaging the SwitchStep12Click Submit to save your changes and to complete the initial setup.After you click Submit:•The switch is configured and exits Express Setup mode.•The browser displays a warning message and tries to connect with the earlier switch IP address. Typically, connectivity between the PC or laptop and the switch is lost because the configured switch IP address is in adifferent subnet from the IP address on the PC or laptop.For more information about Express Setup fields, see the online help for the Express Setup window.Step13Disconnect the switch from the PC or laptop, and install the switch in your network. See the “Installing the Switch”section on page10.Step14If you changed the static IP address on your PC or laptop in Step2, change it to the previously configured static IP address.Step15See the “Managing the Switch” section on page7 for information about configuring and managing the switch. Step16To display Device Manager:1.Start a web browser on your PC or laptop.2.Enter the switch IP address, username, and password assigned in Step9 in the browser, and press Enter.The Device Manager page appears.Troubleshooting:If Device Manager does not appear:•Confirm that the port LED for the switch port connected to your network is green.•Confirm that the PC or laptop that you are using has network connectivity by connecting it to a well-known web server in your network. If there is no network connection, troubleshoot the network settings on the PC or laptop.•Make sure that the switch IP address in the browser is correct.•If the switch IP address in the browser is correct, the switch interface LED is green, and the PC or laptop has network connectivity, continue troubleshooting by reconnecting the PC or laptop to the switch. Configure astatic IP address on the PC or laptop that is in the same subnet as the switch IP address.When the LED on the switch port connected to the PC or laptop is green, reenter the IP address of the switch in a browser to display Device Manager. When Device Manager appears, you can continue with the configuration. Managing the SwitchAfter completing Express Setup and installing the switch in your network, you can use these options forconfiguration:•Device Manager•Cisco Network Assistant•Command-Line Interface•Other Management OptionsCatalyst 3850 Switch Getting Started GuideManaging the SwitchDevice ManagerThe simplest way to manage the switch is by using Device Manager in the switch memory. This is a webinterface that offers quick configuration and monitoring. You can access it through a web browser.Follow these steps:unch a web browser on your PC or laptop.2.Enter the switch IP address in the web browser, and press Enter. The Device Manager page appears.e Device Manager for basic switch configuration and monitoring. Refer to the Device Manageronline help for more information.Configuration WizardThe Configuration Wizard is a Web-based controller user interface (UI) that lets you complete the initialwireless configuration after you configure the IP address, local username, and password or authorizationusing the authentication server. Using the Web UI, you can configure the controller, WLAN, and radiosfor all initial operations, establish management parameters, set security policies, access softwaremanagement commands, configure system logs, and other tasks.For more information on using the Configuration Wizard, see the switch software configuration guideon Cisco Network AssistantCisco Network Assistant is a software program that you download from and run on your PCor laptop. It offers advanced options for configuring and monitoring multiple devices, includingswitches, switch clusters, switch stacks, routers, and access points. Network Assistant is free—there isno charge to download, install, or use it.To use the Cisco Network Assistant:Step1Go to this Web address: /en/US/products/ps5931/index.htmlNote You must be a registered user, but you need no other access privileges.Step2Click the Download Software link, and select the version you want to download.Step3Find the Network Assistant installer.Step4Download the Network Assistant installer, and run it.

本文主要介绍了Cisco MDS 9124交换机在CLI方式下配置Zone的方法和步骤，该方法也同样适用于使用Cisco MDS NX-OS Release 4.1版本的其它9000系列交换机。

1 MDS 初始化配置1.1配置串口登录Cisco MDS 9000系列交换机在默认没有配置的情况下，只能通过串口进行参数设置如右图所示：初次启动并进入MDS 交换机之后，会出现“Would you liketo enter the basic configuration dialog (yes/no): yes”提示，这里表示是否需要启动向导模式配置该交换机，此处输入“NO”。

然后根据提示输入管理员密码。

1.2 License 配置Cisco MDS 交换机不同于Brocade交换机之处为Cisco MDS 交换机可以单独为某个指定的端口配置license，暂时不使用的端口可以释放端口的license。
