}
}
The returned information depends on the DHCP server type, i.e. some parameters are specific to the DHCPv4 server. Also, some parameters may not be returned if they are not set for the client class. If a class with the specified name does not exist, a result of 3 (empty) is returned. If the client class is found, the result of 0 is returned. If there is an error while processing the command, the result of 1 is returned.

}
]
}
}
The returned list of classes merely contains their names. In order to retrieve full information about one of these classes, use The class-get Command. The returned result is 3 (empty) if no classes are found. If the command is processed successfully and the list of client classes is not empty, the result of 0 is returned. If there is an error while processing the command, the result of 1 is returned.
class-update

Response syntax:
{
"result": 0,
"text": "Class '<class-name>' updated."

If any of the leases is malformed, all changes are rolled back. If the leases are well-formed but the operation fails for one or more leases, these leases are listed in the response; however, the changes are preserved for all leases for which the operation was successful. The “deleted-leases” and “leases” are optional parameters, but one of them must be specified.

The “failed-deleted-leases” holds the list of leases which failed to delete; this includes leases which were not found in the database. The “failed-leases” includes the list of leases which failed to create or update. For each lease for which there was an error during processing, insertion into the database, etc., the result is set to 1. For each lease which was not deleted because the server did not find it in the database, the result of 3 is returned.

If the server tag “all” is included in the command, the response contains the global parameters shared among all servers. It excludes server-specific global parameters. If an explicit server tag is included in the command, the response contains all global parameters directly associated with the given server, and the global parameters associated with all servers when server-specific values are not present.
remote-global-parameter6-set
This command creates or updates one or more global parameters in the configuration database.
Supported by: kea-dhcp6
Availability: 1.6.0 (cb_cmds hook library)
Access: write (parameter ignored in this Kea version)
Description and examples: see remote-global-parameter6-set command
Command syntax:
{
"command": "remote-global-parameter6-set",
"arguments": {
"parameters": {
<first parameter name>: <first parameter value>,
<second parameter name>: <second parameter value>
},
"remote": {
<specification of the database to connect to>
},
"server-tags": [ <single server tag as string> ]
}
}
This command carries multiple global parameters with their values. Care should be taken when specifying more than one parameter; in some cases, only a subset of the parameters may be successfully stored in the database and other parameters may fail to be stored. In such cases the remote-global-parameter6-get-all command may be useful to verify the contents of the database after the update. The server-tags list is mandatory and must contain exactly one server tag. Specifying an empty list, a value of null, or multiple server tags will result in an error. The server tag “all” is allowed; it associates the specified parameters with all servers.
Response syntax:

"arguments": {
"parameters": {
<first parameter name>: <first parameter value>,

If an explicit server tag is included in the command, the response contains all global options directly associated with the given server, and the options associated with all servers when server-specific options are not present.
remote-option4-global-set

remote-server6-del
This command deletes information about a DHCPv6 server from the configuration database. Any configuration explicitly associated with the deleted server is automatically disassociated. In addition, configuration elements not shareable with other servers (e.g. global DHCP parameters) are deleted. Shareable configuration elements (e.g. subnets, shared networks) are not deleted as they may be used by other servers.
