Is it possible to schedule "Clear aaa radius-server cache"?

fstorer — Thu, 19 Sep 2019 20:06:04 GMT

Hello,

We have an access point working as Radius server (AP250, HiveOS 8.2r4). It works fine until the cache receives its limit of 512. Is there a way to schedule the clearing of the cache every day (or, even better, every few hours)? We are having a lot of connection issues and at the moment the only way to solve this is clearing the cache manually every morning. I hope you can help!

You could make a supplemental CLI object with that command, but then you'd have to schedule a reboot of the AP to apply the supplemental CLI commands. Unfortunately we don't have a way to schedule CLI commands without any reboot, but I can submit a feature request to see if we can add this to a later release if you'd like?

Thanks for the quick reply, Sam!

Yes, please, it would be great to see this feature in a future release!

Thanks again

Thanks for getting back to me so quickly, I've filed that feature request for you now. Please feel free to check in with me later on and I will check on the status of the request for you.

Dear Sam,

It seems I have another issue now.

I have set the supplemental CLI object with the "clear cache" command and then the reboot schedule (reboot schedule daily every 1 day(s) time 06:30:00) on the AP. When the AP reboots, somehow it loses the "schedule" config. I saved the config (save config running current), but after rebooting the AP doesn't keep the "schedule" config, which means it doesn't reboot anymore. If I type "show reboot schedule" on the CLI, I get nothing. Am I doing something wrong? Should I check other settings?

Thank you in advance for your help!

Unfortunately if you configure anything in the CLI it gets erased when the AP reboots. You'd want to schedule the reboots in HiveManager instead so that configuration sticks through any reboots or updates.

Thanks Sam! As I have never scheduled the reboots in HiveManager, is there a webpage/document where I can see how to set it up? Is it possible to apply the daily schedule only on one AP?

Could you let me know which HiveManager platform you are using? The instructions will vary depending on the platform in use. This guide will walk you through how to determine which HiveManager you are using, for reference: https://thehivecommunity.aerohive.com/s/article/Which-HiveManager-Platform-am-I-using

Hi Sam, thanks for your support.

According to that webpage, we are using the HiveManager (formerly NG) Build Version 19.8.1.5. The GUI tool bar at the top starts with "Dashboard".

Thank you for letting me know, here is a guide for how to set that up in HiveManager: https://thehivecommunity.aerohive.com/s/article/How-to-Schedule-a-Reboot-in-HiveManager

Thanks for the guide, one more question: if I set only the time (let's say 6:30AM), will the AP reboot every day at that time? I would like to set a daily, "recurring reboot" for that AP. Is that allowed? Or do I need to set it manually every day?

I believe you'd have to set it again, but let me check for you and I'll let you know what I find.

Thank you for your patience, I was able to confirm that we are only able to schedule one reboot at a time, so you would have to reset that each day.

To address the problem of the logs filling up so quickly, that indicates that your Radius set up is too large to be properly handled by an AP and we would recommend setting up an external user database (active directory or LDAP) that we can link the APs to. That would eliminate the need to constantly manually clear the cache.

Hi @Sam Pirok ,

Thank you for your reply. I was wondering if reducing the lifetime of the cache (the default is 86400 seconds, which means 24 hours) can help that. Do you think I can improve the "clearing" if I set the maximum lifetime to 3600 seconds (1 hour)?

Yes that would cause the cache to clear more frequently, so that should reduce the number of alerts you're getting about the cache filling up.
