Re: Pre-download image to multiple ap's on 5520 WLC

DAVID · ‎07-10-2018

I need to pre-download a new image to 600+ ap's but I don't want to do all at the same time or one at a time. Is it possible to pre-download the image to the AP's in batches of 20 to 50 at a time?

Hi

I didn't take it from Cisco docs but for experience. Last time I had to that I realized that the WLC itself doesn't send the image to all AP at once. As far I remember I could see the number was around 10.

You can also see this here:

Pre-download works globally or individually.
So if you want a batch, then you'll need to click each individual AP (or using CLI).

Is it possible to use PI to pre-download the image to the APs? How would you do this through the CLI? I know how to do the ap image pre-download primary all /AP-NAME but how can I do batches of AP names in the cli? I can't have all 600+ ap's are downloading at the same time but I can't be stuck doing one ap at a time either.

Hi David,

May be if you have AP's in flex-connect you can check below link:

First, generate a list of APs using CLI: sh ap summary
Put the list in a spreadsheet and sort it.
Then specify which APs will do the pre-download using the command "config ap image predownload primary <AP name>".
