Efficient image upgrades for FlexConnect APs
Efficient image upgrade is an optimized upgrade method for FlexConnect APs that
-
reduces WAN link load by limiting simultaneous image downloads to three secondary APs per primary AP.
-
allows simultaneous secondary AP downloads from a designated primary AP, and
-
enables faster image pre-downloads for FlexConnect APs.

Analogy: relay race
Efficient image upgrades work like a relay race for file sharing. Imagine a group of runners (APs) at a remote location needing a baton (the software image) from the main building (the controller). Instead of each runner making the trip directly and crowding the hallway (the WAN link), one designated runner (the primary AP) gets the baton first and brings it back. The others then take the baton from this runner in controlled small groups (three at a time), so the hallway never gets overcrowded, saving time and reducing congestion.
