Configuring LACP in J-Web

Use the link aggregation feature to aggregate one or more Ethernet interfaces to form a virtual link or link aggregation group (LAG). The MAC client can treat this virtual link like a single link. Link aggregation increases bandwidth, provides graceful degradation as failure occurs, and increases availability.

You can use the J-Web interface to add a new LAG or to edit or delete an existing LAG.

Note: The interfaces that are already configured with MTU, duplex, flow control, or logical interfaces are displayed. However, when you select an already configured interface, a warning message is displayed.

To access the LACP Configuration:

  1. In the J-Web user interface, select Configure>Interfaces>Link Aggregation.

    The Aggregated Interfaces list is displayed.

  2. Click one of the following:
    • Device Count—Creates an aggregated Ethernet interface, or LAG. You can choose the number of device that you want to create. Information displayed on the link aggregation page are specified in Table 17 and the details of aggregation are specified in Table 18
    • Add—Adds a new aggregated Ethernet Interface, or LAG. Enter information as specified in Table 19.
    • Edit— Modifies a selected LAG
      • Aggregation—Modifies an selected LAG. Enter information as specified in Table 19.
      • VLAN—Specifies VLAN options for the selected LAG. See Table 20 for details on the options.
      • IP Option—Configuring IP address to LAG is not supported and when you try to configure the IP address an error message is displayed.
    • Delete—Deletes the selected LAG.
    • Disable Port or Enable Port—Disables or enables the administrative status on the selected interface.
  3. Click one:
    • Click OK to check your configuration and save it as a candidate configuration, then click Commit Options>Commit.
    • Click Cancel to cancel the configuration without saving changes.
