Re: Failover state changes (Chris Buxton) ---------------------------------------------------------------------- Message: 1 Date: Wed, 18 Dec 2019 08:42:34 -0800 From: Chris Buxton <cli...@buxtonfamily.us> To: Users of ISC DHCP <dhcp-users@lists.isc.org> Subject: Re: Failover state changes Message-ID: <6ef4cf81-7487-4ad9-9d06-d8c6ac0c0...@buxtonfamily.us> Content-Type: text/plain; charset=us-ascii I can answer the latter question. Yes, max-unacked-updates affects recovery time when there are a large number of dynamic addresses, whether they have been assigned to client devices or not. Every available lease, whatever state, must be synchronized with the peer. Increasing the number of leases that can be sent at a time definitely appears to help speed this process along. I use a value of 1000 for this purpose, rather than the default of 10, and I've never seen any problems resulting.
