Adding interfaces into on-box DNS Load Balancing

Panther411 — Wed, 04 Jun 2025 09:53:19 GMT

We just added in a new AFF A400 in our prod cluster and we'll be needing to add 4 new network interfaces (2 CIFS and 2 NFS) in for load balancing.

On-box load balancing is configured to use delegation. What is the impact when configuring new network interfaces for existing on-box load balancing if any?

It should simply work according to the LIF's-weight. Every LIF is assigned a weight based on its port load and CPU utilization of its home node (All this is handled automatically by the on-box DNS Load balancer). LIFs that are on less-loaded ports have a higher probability of being returned in a DNS query, hence no impact of adding adding Lifs.

Add or remove a LIF from a load balancing zone:
