Configuring the Switch Using the Web User Interface

This document walks you through the steps to access and configure your switch using the Web UI.


Note

Any figures included in the document are shown for illustrative purposes only.

Introduction to Day 0 WebUI Configuration

After you complete the hardware installation, you need to setup the switch with configuration required to enable traffic to pass through the network. On your first day with your new device, you can perform a number of tasks to ensure that your device is online, reachable and easily configured.

The Web User Interface (Web UI) is an embedded GUI-based device-management tool that provides the ability to provision the device, to simplify device deployment and manageability, and to enhance the user experience. You can use WebUI to build configurations, monitor, and troubleshoot the device without having CLI expertise.

You have two methods to configure the switch using the WebUI.

Figure 1. WebUI Day 0 Wizard


Cisco DNA Center Cloud Onboarding Day 0 Wizard

Use this wizard to configure the management interface and check if it is reachable through the cloud.


Note

You must add the device to your Cisco DNA Center Cloud account before proceeding with this wizard.

Configuring Account Settings

Setting a username and password is the first task you will perform on your device. Typically, as a network administrator, you will want to control access to your device and prevent unauthorized users from seeing your network configuration or manipulating your settings.

Procedure

Step 1

Log on using the default username webui and password cisco.

Step 2

Set a password of up to 25 alphanumeric characters.

The username password combination you set gives you privilege 15 access. The string cannot start with a number, is case sensitive, and allows spaces but ignores leading spaces.

Step 3

In the Device ID Settings section, type a unique name in the Device Name field to identify your device in the network.

Step 4

Enter the date and time for your device manually in the Time & Device Mode field. To synchronize your device with an external timing mechanism such as a Network Time Protocol (NTP) clock source, enter the IP address in the NTP Server field.

Configuring Basic Device Settings

On the Basic Settings page configure the following information:

Procedure

Step 1

In the Device Management Settings section, assign an IP address to the management interface using either Static or DHCP address.

Step 2

If you chose Static, perform the following steps:

  1. Enter a VLAN ID to associate with the interface in the Associate VLAN Interface drop-down list.

  2. Ensure that the IP address you assign is part of the subnet mask you enter.

  3. Optionally, enter an IP address to specify the default gateway.

  4. Enter the address of the DNS Server.

Figure 3. Basic Settings - Static Configuration


Step 3

If you chose DHCP, perform the following steps:

  1. Enter a value in the VLAN ID field.

    VLAN ID must be a value other than 1.

  2. Ensure that the IP address you assign is part of the subnet mask you enter.

  3. Optionally, enter an IP address to specify the default gateway.

  4. Enter the address of the DNS Server.

Step 4

Verify that the configurations are applied successfully, and the device is redirected to Cisco DNAC Cloud.

What to do next

If redirection does not succeed, verify if the device is associated with a redirection controller profile on Cisco PnP Connect (devicehelper).

Classic Day 0 Wizard

Use this wizard to configure the device with basic and advanced settings. Once complete, you can access the device through the WebUI using the management interface IP address.

Connecting to the Switch

Before you begin

Set up the DHCP Client Identifier on the client to get the IP address from the switch, and to be able to authenticate with Day 0 login credentials.

Setting up the DHCP Client Identifier on the client for Windows

  1. Type regedit in the Windows search box on the taskbar and press enter.

  2. If prompted by User Account Control, click Yes to open the Registry Editor.

  3. Navigate to

    Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\ and locate the Ethernet Interface Global Unique Identifier (GUID).

  4. Add a new REG_BINARY DhcpClientIdentifier with Data 77 65 62 75 69 for webui. You need to manually type in the value.

    Figure 6. Setting up DHCP Client Identifier on Windows

  5. Restart the PC for the configuration to take effect.

Setting up the DHCP Client Identifier on the client for MAC

  1. Go to System Preferences >Network >Advanced >TCP >DHCP Client ID: and enter webui.
    Figure 7. Setting up DHCP Client Identifier on MAC

  2. Click OK to save the changes.

The bootup script runs the configuration wizard, which prompts you for basic configuration input: (Would you like to enter the initial configuration dialog? [yes/no]: ). To configure Day 0 settings using the web UI, do not enter a response. Perform the following tasks instead:

Procedure

Step 1

Make sure that no devices are connected to the switch.

Step 2

Connect one end of an ethernet cable to one of the downlink (non-management) ports on the active supervisor and the other end of the ethernet cable to the host (PC/MAC).

Step 3

Set up your PC/MAC as a DHCP client, to obtain the IP address of the switch automatically. You should get an IP address within the 192.168.1.x/24 range.

Figure 8. Obtaining the IP Address

It may take up to three mins. You must complete the Day 0 setup through the web UI before using the device terminal.

Step 4

Launch a web browser on the PC and enter the device IP address (https://192.168.1.1) in the address bar.

Step 5

Enter the Day 0 username webui and password cisco.

What to do next

Create a user account.

Creating User Accounts

Setting a username and password is the first task you will perform on your device. Typically, as a network administrator, you will want to control access to your device and prevent unauthorized users from seeing your network configuration or manipulating your settings.

Procedure

Step 1

Log on using the default username and password provided with the device.

Step 2

Set a password of up to 25 alphanumeric characters. The username password combination you set gives you privilege 15 access. The string cannot start with a number, is case sensitive, and allows spaces but ignores leading spaces.

Configuring Your Device Based on a Site Profile

To ease your configuration tasks and save time, choose a site profile based on where your device may be installed and managed in your network. Based on the site profile you choose, your device is automatically configured according to Cisco best practices. You can easily modify this default configuration, from the corresponding detailed configuration screens.

Choosing a site profile as part of Quick Setup allows you to configure your device based on the business needs of your enterprise. For example, you could use your device as an access switch, to connect client nodes and endpoints on your network, or as a distribution switch, to route packets between subnets and VLANs.

Configuring VLAN Settings

Procedure

Step 1

In the VLAN Configuration section, you can configure both data and voice VLANs. Type a name for your data VLAN.

Step 2

To configure a data VLAN, ensure that the Data VLAN check box is checked, type a name for your VLAN, and assign a VLAN ID to it. If you are creating several VLANs, indicate only a VLAN range.

Step 3

To configure a voice VLAN, ensure that the Voice VLAN check box is checked, type a name for your VLAN, and assign a VLAN ID to it. If you are creating several VLANs, indicate a VLAN range.

Configuring STP Settings

Procedure

Step 1

RPVST is the default STP mode configured on your device. You can change it to PVST from the STP Mode drop-down list.

Step 2

To change a bridge priority number from the default value 32748, change Bridge Priority to Yes and choose a priority number from the drop-down list.
