After you purchase a Smart Access Gateway (SAG) device, the system creates an SAG instance that allows you to manage the SAG device. This topic describes how to view basic information about an SAG device through the SAG instance.

Procedure

  1. Log on to the Smart Access Gateway console.
  2. In the top navigation bar, select the region.
  3. On the Smart Access Gateway page, click the ID of the SAG instance.
  4. On the instance details page, you can view the basic information about the SAG instance on the Basic Info tab.
    The Basic Info tab displays the basic information and advanced features:
    • Basic Info: displays information such as the model of the SAG device associated with the current SAG instance, upstream bandwidth, and route advertisement methods.
      Parameter Description
      SAG instance ID The ID of the SAG instance.
      SAG Instance Name The name of the SAG instance.

      You can click Edit to modify the name.

      The name must be 2 to 100 characters in length, and can contain digits, underscores (_), and hyphens (-). It must start with a letter.

      Description The description of the SAG instance.

      You can click Edit to modify the description.

      The description must be 2 to 256 characters in length and can contain digits, underscores (_), and hyphens (-). It must start with a letter.

      WAN Upstream Bandwidth The maximum upstream bandwidth of the SAG device when the SAG device is connected to the Internet through a WAN port. Unit: Mbit/s.

      You can click Edit to modify the maximum upstream bandwidth.

      Upstream Bandwidth of Cellular Port The maximum upstream bandwidth of the SAG device when the SAG device is connected to the Internet through 4G networks. Unit: Mbit/s.

      You can click Edit to modify the maximum upstream bandwidth.

      Method to Synchronize with On-premises Routes The method that the SAG device uses to advertise routes to Alibaba Cloud. For more information, see Advertise routes to Alibaba Cloud.
      Controller Status The status of the SAG device.
      • Order Placed: The order of the SAG device has been placed and the package has not been dispatched.
      • Order Shipped: The package has been dispatched. After you receive the package, sign for it.
      • Not Associated with CCN: The SAG instance is not associated with a Cloud Connect Network (CCN) instance or virtual boarder router (VBR).
      • Disconnected: The SAG device is not connected to Alibaba Cloud.
      • Ready: The SAG device is working as expected.
      • Overdue Payment: The SAG device is unavailable due to overdue payments.
      VPN Status The status of the VPN connection through which the SAG device is connected to Alibaba Cloud.
      • Normal: The VPN connection is working as expected.
        If the VPN connection is working as expected, you can place the pointer over Normal to view the protocol that the VPN connection uses, including:
        • ipsecVPN: uses Internet Protocol Security (IPsec). By default, the SAG device uses IPsec to establish the VPN connection.
        • aliVPN: uses the Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) to provide an enhanced VPN connection, encapsulate data packets on any port, minimize packet loss, and improve data transmission efficiency.

          You can submit a ticket to enable aliVPN.

      • Abnormal: The VPN connection is not working as expected.
      Created At The time when the SAG instance was created.
      Expires At The date when the SAG instance expires.
      Device Model The model of the SAG device that is associated with the SAG instance.
    • Advanced Features: displays advanced features such as quality of service (QoS) policies, access control lists (ACLs), and deep packet inspection (DPI).
      Parameter Description
      DPI Indicates whether DPI is enabled.

      You can turn on or turn off the switch to enable or disable DPI.

      Note
      QoS Policy The QoS policy that is associated with the SAG instance. For more information about QoS policies, see What is a QoS policy?.
      Transmission Optimization Indicates whether transmission optimization is enabled.

      Transmission optimization uses forward error correction (FEC) to minimize packet loss. This makes data transmission more reliable.

      To enable transmission optimization, submit a ticket.

      Flow Log The flow log that is associated with the SAG instance. For more information about flow logs, see Overview.
      ACL The ACL that is associated with the SAG instance. For more information about ACLs, see Overview.
