Configuring Aggregated Ethernet Interfaces (J-Web Procedure)

Note:

This topic applies only to the J-Web Application package.

Use the link aggregation feature to aggregate one or more Ethernet interfaces to form a virtual link or LAG on an EX Series switch. The MAC client can treat this virtual link as if it were a single link. Link aggregation increases bandwidth, provides graceful degradation when failure occurs, and increases availability. You can use the J-Web interface to configure LAGs, on the switch.

Note:

Interfaces that are already configured with MTU, duplex, flow control, or logical interfaces are listed but are not available for aggregation.

To configure a LAG:

  1. Select Configure > Interfaces > Link Aggregation.

    The list of aggregated interfaces is displayed.

    Note:

    After you make changes to the configuration on this page, you must commit the changes immediately for them to take effect. To commit all changes to the active configuration, select Commit Options > Commit. See Using the Commit Options to Commit Configuration Changes (J-Web Procedure) for details about all commit options.

  2. Select one of the following:

    • Add—Creates a LAG. Enter information as specified in Table 1.

    • Edit—Modifies a selected LAG.

      • Aggregation—Modifies settings for the selected LAG. Enter information as specified in Table 1.

      • VLAN—Specifies VLAN options for the selected LAG. Enter information as specified in Table 2.

      • IP Option—Specifies IP options for the selected LAG. Enter information as specified in Table 3.

    • Delete—Deletes the selected LAG.

    • Disable Port or Enable Port—Disables or enables the administrative status on the selected interface.

    • Device Count—Configures the number of aggregated logical devices available to the switch. Select the number and click OK.

Field

Function

Your Action

Aggregated Interface

Specifies the name of the aggregated interface.

None. The name is supplied by the software.

LACP Mode

Specifies the mode in which Link Aggregation Control Protocol (LACP) packets are exchanged between the interfaces. The modes are:

  • None—Indicates that no mode is applicable.

  • Active—Indicates that the interface initiates transmission of LACP packets

  • Passive—Indicates that the interface responds only to LACP packets.

Select from the list.

Description

Specifies a description for the LAG.

Enter a description.

Interface

Specifies the interfaces in the LAG.

To add interfaces to the LAG, select the interfaces and click Add. For an EX8200 Virtual Chassis configuration, select the member, FPC, and the interface from the list. Click OK.

To remove an interface from the LAG, select the interface and click Remove.

Note:

Only interfaces that are configured with the same speed can be selected together for a LAG.

Enable Log

Specifies whether to enable generation of log entries for the LAG.

Select the check box to enable log generation, or clear the check box to disable log generation.

Your Action

Port Mode

Specifies the mode of operation for the port: trunk or access.

If you select Trunk, you can:

  1. Click Add to add a VLAN member.

  2. Select the VLAN and click OK.

  3. (Optional) Associate a native VLAN ID with the port.

If you select Access, you can:

  1. Select the VLAN member to be associated with the port.

  2. (Optional) Associate a VoIP VLAN with the interface. Only a VLAN with a VLAN ID can be associated as a VoIP VLAN.

Click OK.

Field

Function

Your Action

IPv4 Address

Specifies an IPv4 address for the selected LAG.

  1. Select the check box IPv4 address.

  2. Type an IP address—for example, 10.10.10.10.

  3. Enter the subnet mask or address prefix. For example, 24 bits represents 255.255.255.0.

  4. Click OK.

IPv6 Address

Specifies an IPv6 address for the selected LAG.

  1. Select the check box IPv6 address.

  2. Type an IP address—for example, 2001:ab8:85a3::8a2e:370:7334.

  3. Enter the subnet mask or address prefix.

  4. Click OK.
