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.
a Select a distributed switch and click the Networks tab.
b 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.
Limitations of the LACP Support on a vSphere Distributed
Switch
The LACP support on a vSphere Distributed Switch lets network devices to negotiate automatic bundling
of links by sending LACP packets to a peer. However, the LACP support on a vSphere Distributed Switch
has limitations.
n
The LACP is not supported with software iSCSI port binding. iSCSI multipathing over LAG is
supported, if port binding is not used.
n
The LACP support settings are not available in host profiles.
n
The LACP support is not possible between nested ESXi hosts.
n
The LACP support does not work with the ESXi dump collector.
n
The LACP control packets (LACPDU) do not get mirrored when port mirroring is enabled.
n
The teaming and failover health check does not work for LAG ports. LACP checks the connectivity of
the LAG ports.
n
The enhanced LACP support works correctly when only one LAG handles the traffic per distributed
port or port group.
