You can enable LACP support on an uplink port group for vSphere Distributed Switches 5.1, and for switches upgraded to 5.5 or 6.0 that do not have the enhanced LACP support.

Prerequisites

  • Verify that for each host where you want to use LACP, a separate LACP port channel exists on the physical switch.
  • Verify that distributed port groups have their load balancing policy set to IP hash.
  • Verify that the LACP port channel on the physical switch is configured with IP hash load balancing.
  • Verify that distributed port groups have network failure detection policy set to link status only.
  • Verify that distributed port groups have all uplinks set to active in their teaming and failover order.
  • Verify that all physical NICs that are connected to the uplinks have the same speed and are configured at full duplex.

Procedure

  1. In the vSphere Web Client, navigate to an uplink port group.
    1. Select a distributed switch and click the Networks tab.
    2. Click Uplink Port Groups and select the uplink port group.
  2. Click the Configure tab and select Properties.
  3. Click Edit.
  4. In the LACP section, use the drop-down list to enable LACP.
  5. Set the LACP negotiating mode for the uplink port group.
    Option Description
    Active All uplink ports in the group are in an Active negotiating mode. The uplink ports initiate negotiations with the LACP-enabled ports on the physical switch by sending LACP packets.
    Passive All uplink ports are in a Passive negotiating mode. They respond to LACP packets that they receive but do not initiate LACP negotiation.
    If the LACP-enabled ports on the physical switch are in Active negotiating mode, you can set the uplink ports in Passive mode and the reverse.
  6. Click OK.
