Hi Andy, I altered my configuration to remove the pool and add the ip of ens256. I was able to delete just one entry from the subnet as before. Perhaps provide your configuration and all of your API commands and I could try using your (slightly modified to match interface) configuration? Here are all of my API commands and configuration (attached).
API commands executed like this:
$ cat reservation-get-all.json | sudo socat UNIX:/tmp/socket6
-,ignoreeof | jq .
{
"arguments": {
"hosts": [
{
"client-classes": [],
"duid": "1a:1b:1c:1d:1e:0a",
"hostname": "",
"ip-addresses": [
"2001:db8::101"
],
"option-data": [],
"prefixes": [],
"subnet-id": 1
}
]
},
"result": 0,
"text": "1 IPv6 host(s) found."
}
Thank you,
Darren Ankney
