LACP turn off

Hi, We have many HP 2650 switches which are enabled LACP by default. LACP passive cause many logging event on port on/off. We decided to turn the LACP off to avoid the port on/off action. But when we as soon as did it, the switch telnet session froze and we could not telnet to the switch any more.Do you know why?
"config t
int all
no LACP"
Appreciate your help!

Re: LACP turn off

apearently you have an LACP link between the command-terminal and the switch you are configuring.
When having a double connection between two sitches, and not running STP, you create a network loop.

Either activate STP, or Instead of "int all", do the "no lacp" command on separate interfaces.

Especially exclude the inter-switch interfaces!
I'd say you DO want link on/of from these ports logged!
And you DO want LACP to provide a redundant link between the switches if possible!
