LACP rate change

[MartinKy]

Hello,

we have a cluster of two firewall nodes in production use.
Towards Cisco switches, we have LACP configured, but it seems that there is a mismatch in LACP rate.

Unfortunately we are unable to change it on Cisco side, where we have slow LACP rate.
On CheckPoint box we have Fast LACP rate configured.

To make the configuration consistent, we would like to configure the LACP slow rate on the Check Point FW as well.

As the firewalls are in productive use, does changing LACP rate impose any risk or drop?
Like interface up/down and so on

Thanks and Regards
Martin

Commonly such a change might be applied to the standby member first and then after some time traffic failed across (which is stateful using ClusterXL_admin cmds) to this member and the change repeated on the new standby member.

Depending on your choice of cluster mode some customers may opt to go a step further and force the standby member down during the activity and manually bring it up again after as an additional measure of 'control', but it depends on the operating environment.
