Thanks for the reply Darren! You got my brain working again, as I had basically given up on this.
As it turns out, enabling "store-extended-info" clashes with the functionality of the limits hook, since both of them write to the user-context object via a property named "ISC". We had this enabled globally. It's worth noting that there is an aside on the below docs page that states nothing should interfere with this setting as long as it's not also using the "ISC" property. I'd like to see an additional section or paragraph add to this doc, stating that the limits hook (and any others) WILL clash with this property.

I ran a test using option 82 circuit ID (sub-option 1 which was ascii "An Option 82.1 Circuit-id") with perfdhcp like this: perfdhcp -4 -r 1 -R 20 -p 3600 -o 82,0119416E204F7074696F6E2038322E3120436972637569742D6964 -l ens256 This would spawn a class based on that circuit-id and add each of the 20 clients specified above to the spawned class: 2025-02-13

I'm not exactly sure what trouble you are having but hopefully this example helps you work through the problem. Thank you, Darren Ankney On Mon, Feb 10, 2025 at 9:17?AM Jason Creviston <jcrevis...@weendeavor.com<mailto:jcrevis...@weendeavor.com>> wrote: Hello, New to Kea and trying to get class spawning to work. This was easy to figure out and setup with the EOL'd ISC DHCP server software, but having trouble getting it to work in Kea. I'm testing using three laptops, and all three are getting IPs. I'm trying to limit IPs to two, per option 82 info. I saw in the docs that this mechanism doesn't work 100% under heavy load, but I'm literally just testing with three devices - no other devices are using the server. Anything look incorrect or missing? "client-classes": [ { "name": "everyone", "template-test": "option[82].hex", "user-context": { "limits": { "address-limit": 2 } } } ] I read that the order of hooks is important, so I have the limits one towards the top: "hooks-libraries": [{ "library": "/usr/lib/x86_64-linux-gnu/kea/hooks/libdhcp_legal_log.so" }, { "library": "/usr/lib/x86_64-linux-gnu/kea/hooks/libdhcp_limits.so" }, { "library": "/usr/lib/x86_64-linux-gnu/kea/hooks/libdhcp_stat_cmds.so" }, { "library": "/usr/lib/x86_64-linux-gnu/kea/hooks/libdhcp_lease_cmds.so", "parameters": { } }, { "library": "/usr/lib/x86_64-linux-gnu/kea/hooks/libdhcp_class_cmds.so" }, { "library": "/usr/lib/x86_64-linux-gnu/kea/hooks/libdhcp_subnet_cmds.so" }, { "library": "/usr/lib/x86_64-linux-gnu/kea/hooks/libdhcp_ha.so", And here is a look at the user contexts for each lease. They all appear to have the same content - which I'd expect when they're all behind a single ONT device (implying the same option 82 info, therefore same spawn class). I do find the "," a bit confusing though. { "ISC": { "relay-agent-info": { "remote-id": "43584E4B3030464530454543", "sub-options": "0x01184E4F434C41422045746820312F312F312F312F67313A3131020C43584E4B3030464530454543" } } } { "ISC": { "relay-agent-info": { "remote-id": "43584E4B3030464530454543", "sub-options": "0x01184E4F434C41422045746820312F312F312F312F67313A3131020C43584E4B3030464530454543" } } } { "ISC": { "relay-agent-info": { "remote-id": "43584E4B3030464530454543", "sub-options": "0x01184E4F434C41422045746820312F312F312F312F67313A3131020C43584E4B3030464530454543" } } } Thanks, Jason Creviston Sr. Network Administrator P: 765-795-9305 2 S.
