Chapter: Gateway Management

Gateway Management

A gateway can be associated to a broadcast domain to become the default gateway for the subnet. Although gateways are created with broadcast domains, they contain properties that you can only edit from the INTERFACES tab after they have been created. This chapter explains how to edit and delete a gateway. It has the following sections:

Creating Gateways

Gateways are created with broadcast domains. For information on creating broadcast domains and gateways, see Creating a Broadcast Domain .

Editing a Gateway

This section explains how to edit a gateway.

Before You Begin

At least one gateway has been created.

    Step 1   From the Navigation drop-down list, choose Home.
    Step 2   Click the INTERFACES tab.
    Step 3   (Optional)From the Filter by interface class drop-down list, choose Gateway.

    The gateway tiles appear.

    Step 4   Click the name inside the gateway interface tile you want to edit. A gateway-specific window appears with a summary pane on the right that contains the EDIT option.
    Step 5   Click EDIT. The GATEWAY SETTINGS dialog box appears with the GENERAL SETTINGS tab.
    Step 6   Enter the appropriate values in the fields of each tab as listed in the GATEWAY SETTINGS Dialog Box Fields table below then continue to step 8.

      Step 5   Click DELETE. The DELETE dialog box appears.
      Step 6   Click DELETE.

      Viewing Gateway Details

      Once a gateway has been created as part of a broadcast domain creation task, a specific gateway object and associated gateway tile is created. To view the details of a gateway, you must access the gateway tile via the Interfaces tab. Clicking the name on a gateway tile enables you to view detailed information about that gateway such as the number of Rx bits and packets sent per second, when the gateway was created, and when it was last modified. The following task explains how to find this information.

      Before You Begin

      At least one gateway has been added.

        Step 1   From the Navigation drop-down list, choose Home.
        Step 2   Click the INTERFACES tab.
        Step 3   (Optional)From the Filter by interface class drop-down list, choose Gateway.

        The gateway tiles appear.

        Step 4   Click in a tile.

        A summary pane appears on the right with the following gateway information:

        • Description—Description of the gateway

        • MAC address—MAC address of the anycast gateway

          Note   

          As by design, the same MAC address is used by all gateways, within all broadcast domains, on all switches within a managed fabric. This MAC address can be changed via the switchpool settings options.

        • MTU—Operational MTU that is being used for the gateway interface

        • VRF—The VRF in which the gateway interface resides

        • Broadcast domain—The broadcast domain to which the gateway interface is associated

        • IP address—IP address of the gateway interface

        Step 5   Click the name inside the gateway tile you want to view.

        A gateway-specific window appears with the following tabs:

        • OVERVIEW—Displays the following:

          • BITS PER SECOND—Received (Rx) bits per second statistics for the gateway

          • PACKETS PER SECOND—Received (Rx) packets per second statistics for the gateway

          • GENERAL—General information such as when the gateway was created and when the gateway was last modified

        • COMMENT—Icon for adding a comment
