After offloading the management of LACP from the VSM to the VEM, you must preserve the running
configuration in the startup configuration and reload the VSM before the offload takes effect. This
procedure has steps for doing this.
•
Know that offloading of LACP management to the VEMs is enabled by default on the VSM.
When you upgrade to 4.2(1)SV1(4) or before, the LACP offload management to the
VEMs is disabled by default. However, LACP offload is the only supportable mode
starting with release 5.2(1)SV3(1.1) and VEMs will automatically go into that mode
after you upgrade. We recommend that you add the LACP offload configuration to VSM
for consistency.
