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"
} } }

} } }
