Static Lags - Dell N1100-ON Reference Manual

unable to buffer the requisite number of frames will show excessive frame
discard. Configuring copper and fiber ports together in an aggregation group
is not recommended.
If a dynamic LAG member sees an LACPDU that contains information
different from the currently configured default partner values, that particular
member drops out of the LAG. This configured member does not aggregate
with the LAG until all the other active members see the new information.
When each of the other active members sees the new information, they
continue to drop out of the LAG. When all the members have dropped out of
the LAG, they form an aggregate with the new information.

Static LAGS

A static LAG is fundamentally no different from a dynamically configured
LAG. All the requirements for the member ports hold true (member ports
must have same duplex settings, same speed, and so on). The only difference
is this LAG has an additional parameter static which makes this LAG not
require a partner system running Link Aggregation Control Protocol (LACP)
to be able to aggregate it's member ports.
Care must be taken while enabling this type of configuration. If the Partner
System is not 802.3AD compliant or the Link Aggregation Control protocol is
not enabled, there may be network instability. Network instability occurs
when one side assumes that the members in an aggregation are one single
link, while the other side is oblivious to this aggregation and continues to
treat the 'members' as individual links.
A static LAG does not transmit or process received LACPDUs, that is, the
member ports do not transmit LACPDUs and all the LACPDUs it receives
are dropped. A dropped counter is maintained to count the number of such
PDUs.
Configured members are added to the LAG (active participation)
immediately if the LAG is configured to be static. There is no wait time
before we add the port to the LAG.
A LAG can be either static or dynamic, but not both. It cannot have some
member ports participate in the protocol while other member ports do not
participate. Additionally, it is not possible to change a LAG from static to
dynamic via the CLI. You must remove the member ports from the static
LAG and then add them to the dynamic LAG.
