Port Channel Commands
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. 
A static LAG does not transmit or process received LACPDUs, that is, the 
member ports do not transmit LACPDUs and all the LACPDUs it may 
receive 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.
VLANs and LAGs
When members are added to a LAG, they are removed from all existing 
physical link VLAN membership and gain the VLAN membership of the 
LAG. When members are removed from a LAG, the members rejoin the 
VLANs of which they were previously members per the configuration file.
The LAG interface can be a member of a VLAN complying with IEEE 
802.1Q.
LAG Thresholds
In many implementations, a LAG is declared as up if any one of its member 
ports is active. This enhancement provides configurability for the minimum 
number of member links to be active to declare a LAG up. Network 
administrators can also utilize this feature to automatically declare a LAG 
down when only some of the links have failed.
