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.

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.

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.
