Configuring the Switch Using the Web User Interface


Note

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

Setting up the Switch

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. It comes with the default image, so there is no need to enable anything or install any license on the device. You can use WebUI to build configurations, and to monitor and troubleshoot the device without having CLI expertise.

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 1. 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 2. 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 3. 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 serial number of the switch.

The serial number is case sensitive.

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.

Choosing Setup Options

Select Wired Network to configure your device based on a site profile, and continue to configure switch wide settings. Otherwise, continue to the next step and configure only basic settings for your device.

Configuring Basic Device Settings

On the Basic Device Settings page configure the following information:

Procedure

Step 1

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

Step 2

Choose the date and time settings for your device. To synchronize your device with a valid outside timing mechanism, such as an NTP clock source, choose Automatic, or choose Manual to set it yourself.

Figure 5. Basic Settings - Device ID and Location Settings


Step 3

In the Device Management Settings section, assign an IP address to the management interface. Ensure that the IP address you assign is part of the subnet mask you enter.

Step 4

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

Step 5

To enable access to the device using telnet, check the Telnet check box.

Step 6

To enable secure remote access to the device using Secure Shell (SSH), check the SSH check box.

Step 7

Check the VTP transparent mode check box to disable the device from participating in VTP.

If you did not select Wired Network, in the earlier step, continue to the next screen to verify your configuration on the Day 0 Config Summary screen, and click Finish. To automatically configure your device based on a site profile, click Setup Options, and select Wired Network.

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.

Configure 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.

Configuring DHCP, NTP, DNS and SNMP Settings

Procedure

Step 1

In the Domain Details section, enter a domain name that the software uses to complete unqualified hostnames.

Step 2

Type an IP address to identify the DNS server. This server is used for name and address resolution on your device.

Step 3

In the Server Details section, type the IP address of the DNS server that you want to make available to DHCP clients.

Step 4

In the Syslog Server field, type the IP address of the server to which you want to send syslog messages.

Step 5

To ensure that your device is configured with the right time, date and timezone, enter the IP address of the NTP server with which you want to synchronize the device time.

Step 6

In the Management Details section, type an IP address to identify the SNMP server. SNMPv1, SNMPv2, and SNMPv3 are supported on your device.

Step 7

Specify the SNMP community string to permit access to the SNMP protocol.

What to do next

Configure port settings.

Configuring Port Settings

Procedure

Step 1

Based on the site profile chosen in the earlier step which is displayed in the left-pane, select the Port Role from among the following options:

  • Uplink – For connecting to devices towards the core of the network.
  • Downlink – For connecting to devices further down in the network topology.
  • Access – For connecting guest devices that are VLAN-unaware.
Step 2

Choose an option from the Select Switch drop-down list.

Step 3

Make selections from the Available list of interfaces based on how you want to enable them and move them to the Enabled list.
