+
+.. option:: --project <project>
+
+    Owner's project (name or ID)
+
+.. option:: --project-domain <project-domain>
+
+    Domain the project belongs to (name or ID).
+    This can be used in case collisions between project names exist.
+
+.. option:: --subnet-pool <subnet-pool>
+
+    Subnet pool from which this subnet will obtain a CIDR (name or ID)
+
+.. option:: --use-default-subnet-pool
+
+    Use default subnet pool for --ip-version
+
+.. option:: --prefix-length <prefix-length>
+
+    Prefix length for subnet allocation from subnet pool
+
+.. option:: --subnet-range <subnet-range>
+
+    Subnet range in CIDR notation
+        (required if --subnet-pool is not specified, optional otherwise)
+
+.. option:: --allocation-pool start=<ip-address>,end=<ip-address>
+
+    Allocation pool IP addresses for this subnet e.g.:
+        start=192.168.199.2,end=192.168.199.254 (This option can be repeated)
+
+.. option:: --dhcp
+
+     Enable DHCP (default)
+
+.. option:: --no-dhcp
+
+     Disable DHCP
+
+.. option:: --dns-nameserver <dns-nameserver>
+
+     DNS name server for this subnet (This option can be repeated)
+
+.. option:: --gateway <gateway>
+
+     Specify a gateway for the subnet.  The three options are:
+         <ip-address>: Specific IP address to use as the gateway
+         'auto':       Gateway address should automatically be chosen from
+                       within the subnet itself
+         'none':       This subnet will not use a gateway
+       e.g.: --gateway 192.168.9.1, --gateway auto, --gateway none
+       (default is 'auto')
+
+.. option:: --host-route destination=<subnet>,gateway=<ip-address>
+
+     Additional route for this subnet e.g.:
+         destination=10.10.0.0/16,gateway=192.168.71.254
+         destination: destination subnet (in CIDR notation)
+         gateway: nexthop IP address
+         (This option can be repeated)
+
+.. option:: --ip-version {4,6}
+
+     IP version (default is 4).  Note that when subnet pool is specified,
+         IP version is determined from the subnet pool and this option
+         is ignored.
+
+.. option:: --ipv6-ra-mode {dhcpv6-stateful,dhcpv6-stateless,slaac}
+
+     IPv6 RA (Router Advertisement) mode,
+         valid modes: [dhcpv6-stateful, dhcpv6-stateless, slaac]
+
+.. option:: --ipv6-address-mode {dhcpv6-stateful,dhcpv6-stateless,slaac}
+
+     IPv6 address mode, valid modes: [dhcpv6-stateful, dhcpv6-stateless, slaac]
+
+.. option:: --network <network>
+
+     Network this subnet belongs to (name or ID)
+
+.. _subnet_create-name:
+.. describe:: <name>
+
+     Name of subnet to create
+
