On a host proxy switch, you can connect one physical NIC to only one LAG port. On the distributed
switch, one LAG port can have multiple physical NICs from different hosts connected to it. The physical
NICs on a host that you connect to the LAG ports must be connected to links that participate in an LACP
port channel on the physical switch.
You can create up to 64 LAGs on a distributed switch. A host can support up to 32 LAGs. However, the
number of LAGs that you can actually use depends on the capabilities of the underlying physical
environment and the topology of the virtual network. For example, if the physical switch supports up to
four ports in an LACP port channel, you can connect up to four physical NICs per host to a LAG.
Port Channel Configuration on the Physical Switch
For each host on which you want to use LACP, you must create a separate LACP port channel on the
physical switch. You must consider the following requirements when configuring LACP on the physical
switch:
n
The number of ports in the LACP port channel must be equal to the number of physical NICs that you
want to group on the host. For example, if you want to aggregate the bandwidth of two physical NICs
on a host, you must create an LACP port channel with two ports on the physical switch. The LAG on
the distributed switch must be configured with at least two ports.
n
The hashing algorithm of the LACP port channel on the physical switch must be the same as the
hashing algorithm that is configured to the LAG on the distributed switch.
n
All physical NICs that you want to connect to the LACP port channel must be configured with the
same speed and duplex.

LACP Teaming and Failover Configuration for Distributed
Port Groups
To handle the network traffic of distributed port groups by using a LAG, you assign physical NICs to the
LAG ports and set the LAG as active in the teaming and failover order of distributed port groups.
