The following are general rules for configuring LAGs:
The 7210 SAS-D and 7210 SAS-Dxp support up to four 1GE ports in a LAG. The 7210 SAS-Dxp also supports up to two 10GE ports in a LAG.
The 7210 SAS-K 2F1C2T and 7210 SAS-K 2F6C4T support up to three 1GE ports in a LAG.
The 7210 SAS-K 3SFP+ 8C supports up to three 1GE ports or two 10GE ports in a LAG.
All ports in the LAG must share the same characteristics (speed, duplex, hold-timer, and so on). The port characteristics are inherited from the primary port.
Autonegotiation must be disabled or set to limited mode for ports that are part of a LAG to guarantee a specific port speed.
Ports in a LAG must be configured as full duplex.
The following is a sample LAG configuration output.
