Cisco Nexus 1000V - Guidelines for Troubleshooting Modules

This example shows how to offload management of LACP from the VSM to the VEMs:
switch# configure terminal
switch(config)# lacp offload
Please do a "copy running startup" to ensure the new setting takes effect on next reboot
LACP Offload Status can be verified using "show lacp offload status"
Change in LACP Offload Status takes effect only on the next VSM Reboot
This can potentially cause modules with LACP uplinks to flap
switch(config)# copy running-config startup-config
switch(config)# show lacp offload status
Current Status : Disabled
Running Config Status : Enabled
Saved Config Status : Enabled
switch(config)# reload
This command will reboot the system. (y/n)? [n] y
