Pica8 PicOS for whitebox switches

Posted By Jason Healy 05-02-2024 06:00:00 AM
Found In Egroup: Network Management \ view thread
We've had occasional discussions of whitebox switches on the list, but it's been a while. Wondering if anyone has evaluated PicOS from Pica8 as network OS, and in what capacity. They have a virtual version that I plan to try out, but if anyone else has anything they can share, I'd love to hear it. Since ...

RE: Strange Traffic Spikes

Do the times correlate with anything, like class changes? Our RADIUS logs look like that with spikes as the student pass between classes at the same time. If a big chunk of your clients are reauthenticating to the network at the same time, they might be generating a bunch of mDNS or other discovery ...

We did this a year+ ago and the "gateway" boxes installed by the vendor are rpi with a PoE extractor. We had to get a network cable to where the rpi was, but fortunately didn't have to worry about getting them on wifi. The rpi talk to the laundry appliances via zigbee. They came and did a survey beforehand ...

Aaron, Thank you for sending this along! We have had on and off issues with wifi calling but it hasn't been a big enough deal to dive into it. Your notes will simply give us a jump start. To (partially) answer Seth's question, my provider (AT&T) only lists FQDNs and doesn't promise specific IPs will ...

RE: Aruba controllers losing connectivity after 25 days

Just a quick note as I promised an update: today was day 25 and once again the IPv6 issue struck. I thought it wasn't going to when we passed the 25 day 9 hour mark (when it happened last time). However, just as we hit 25 days 12 hours we lost one, and then two of our four controllers. Spent some time ...

We have upgraded to 8.10.0.9 per TAC's request. The dreaded 25-day window for us will arrive this Sunday afternoon, so we're on standby to see what happens this weekend. I'll try to remember to upgrade the group once I have something to report. Jason -- . Jason Healy Director of Technology . Suffield ...

Another vote for BitWarden here. We are much smaller and so I'm not familiar with all the features you're requesting. For our small group it's done a good job of keeping central access to shared passwords, with group/individual access capabilities for items or categories of items. It has SSO and enterprise ...

Hi Neil, That is interesting that it's in the same timeframe. Our issue is with the controllers losing connectivity (the APs seem fine), so I'm not sure if it's the same. Still, if you could share your case number(s) with me I can pass them along (off list is fine: jhealy@suffieldacademy.org). Meanwhile, ...

Jonathan, That sounds like the same symptoms to me. We've been able to reach the controller through the "dead" gateway as well, and seen other weird behavior (can't SSH to the controller directly, but MDC from the MC works OK). Pings come and go, etc. I'd love your case number (off-list is fine: j ...

This is 8.10.0.8. We were on .7 when the issue first happened and we moved to .8 because TAC thought the issue was resolved in that version. They never got back to me about moving to .9, so we are still on .8 at this time. I imagine they'll want me to upgrade but I don't have high hopes that things ...

Aruba controllers losing connectivity after 25 days

Good morning, this is a quick scream into the void in case someone can help. This summer we upgraded our Aruba cluster to 8.10 and converted it to IPv6-only operation. Since that time we are experiencing an issue where members of the cluster lose connectivity after 25 days of uptime. It's now happened ...

Encryption for Guest/IoT Networks

I wanted to pick the collective brain on this... We have "visitor" and "iot" SSIDs that I'd like to merge into one, along with a NAC/captive portal to sort devices out by role. Right now we have WPA2-PSK on both, but the key is not terribly secret (we rotate the visitor one periodically). I'm leaning ...

We're an all-apple campus using EAP-TLS for eduroam. I decided to be a canary and upgraded my phone yesterday and was able to get on to wifi no issues.

Thank you, the TFTP is what I was looking for. I directly downloaded the image off the controller and it's still 8.8.0.0, so it sounds like the controller's install might be messed up. TAC is having a look at the logs to try and figure that one out now. Thanks for the pointers! Jason -- . Jason ...

Hi Tim, 1) We use Router Advertisements for client configuration. We do have a DHCPv6 server (built into our core router) that serves stateless config options (you should mark the "other" flag in your RA to announce that this is available). This is mostly as a backup for old clients that can't get things ...

I'm opening a case with TAC but hoping for any hints here in the meantime. We're on 8.7 and I have a test controller running 8.10. I've migrated a couple APs to the new setup and they appear to be stuck in a boot loop. The serial output shows the AP being upgraded from 8.7.1.10 to 8.8.0.0, but that's ...

The pros are that you only have one address family to configure and debug, and a much larger pool of addresses available for use. In our case, we don't have nearly enough public IPv4 addresses to give them out to clients, so IPv6 is a way to get global routable addresses (we still firewall them, but ...

I'm glad Stuart brought this up as I was wondering something similar. The last time we did a major rearchitecture, we configured all our switches to support jumbo (9216 IIRC) frames on all interfaces on layer 2. However, we kept all the layer 3 interfaces at normal frame size. I figured that way we'd ...

We did networked laundry in the last 12 months at our school (Automatic Laundry).
