 If you change the Spanning Tree participation of any LAG member to
enabled
or
disabled
, the Spanning Tree participation of all members of that LAG
should be changed similarly.
 When a LAG is enabled, the LAG’s Spanning Tree participation setting takes
precedence over that of any LAG member.
 You cannot configure a LAG member as a monitor port in a port ‐ mirroring
configuration.
 LAGs cannot be monitored by a monitor port; however, LAG members can be
monitored.
 Ports with different link capabilities (speed, duplex, flow control, FEC) can be
configured into the same static or LACP LAG. However, the member port will
be err ‐ disabled if its run ‐ time capability state (speed, duplex, flow control, FEC)
differs from other forward member ports’ run ‐ time capability state in this LAG.
Configuring a Static LAG
In the following example, three ports are aggregated between two switches.
Figure 10.
LAG Configuration Example
Prior to configuring each switch in the preceding example, you must connect to the
appropriate switch’s Command Line Interface (CLI) as the administrator.
Note:
For details about accessing and using any of the menu commands described
in this example, see the Lenovo ENOS Command Reference .
