37 37 DESCRIPTION
38 38 The ipadm command is a stable replacement for the ifconfig(1M) and
39 39 ndd(1M) commands. It is used to create IP interfaces and to configure IP
40 40 addresses on those interfaces. It is also used to get, set or reset
41 41 properties on interfaces, addresses and protocols.
42 42
43 43 For subcommands that take an addrobj, the addrobj specifies a unique
44 44 address on the system. It is made up of two parts, delimited by a `/'.
45 45 The first part is the name of the interface and the second part is a
46 46 string up to 32 characters long. For example, "lo0/v4" is a loopback
47 47 interface addrobj name.
48 48
49 49 For subcommands that take a protocol, this can be one of the following
50 50 values: ip, ipv4, ipv6, icmp, tcp, sctp or udp.
51 51
52 52 SUBCOMMANDS
53 53 The following subcommands are supported:
54 54
55 55 ipadm create-if [-t] interface
56 56 Create an IP interface that will handle both IPv4 and IPv6
57 57 packets. The interface will be enabled as part of the creation
58 58 process. The IPv4 interface will have the address 0.0.0.0. The
59 59 IPv6 interface will have the address ::.

165 165 Specify which protocol to display.
166 166

184 184
185 185 ipadm create-addr [-t] -T static [-d] -a
186 186 [local|remote=]addr[/prefixlen]... addrobj
187 187 Create an address on the specified IP interface using static
188 188 configuration. The address will be enabled but can disabled
189 189 using the ipadm disable-addr subcommand. Note that addrconf
190 190 address configured on an interface is required to configure
191 191 static IPv6 address on the same interface. This takes the
192 192 following options:
193 193
194 194 -a,--address
195 195 Specify the address. The local or remote prefix can be
196 196 used for a point-to-point interface. In this case, both
197 197 addresses must be given. Otherwise, the equal sign ("=")
198 198 should be omitted and the address should be provided by
199 199 itself without second address.
200 200
201 201 -d,--down
202 202 The address is down.
203 203
204 204 -t,--temporary
205 205 Temporary, not persistent across reboots.

207 207 ipadm create-addr [-t] -T dhcp [-1] [-h hostname] [-w {seconds|forever}]
208 208 addrobj
209 209 Create an address on the specified IP interface using DHCP. This
210 210 takes the following options:
211 211
212 212 -1,--primary
213 213 Specify that the interface is primary. One effect will
214 214 be that nodename(4) will serve as -h,--reqhost if that
215 215 switch is not otherwise specified.
216 216
217 217 -h,--reqhost
218 218 Specify the host name to send to the DHCP server in order
219 219 to request an association of a Fully Qualified Domain
220 220 Name to the interface. An FQDN is determined from
221 221 hostname if it is "rooted" (ending in a '.'), or if it
222 222 consists of at least three DNS labels, or by appending to
223 223 hostname the DNS domain name value configured in
224 224 /etc/default/dhcpagent for dhcpagent(1m). N.b. that the
225 225 DHCP server implementation ultimately determines whether
226 226 and how the client-sent FQDN is used.
227 227
228 228 -t,--temporary
229 229 Temporary, not persistent across reboots.
230 230
231 231 -w,--wait
232 232 Specify the time, in seconds, that the command should
233 233 wait to obtain an address; or specify forever to wait
234 234 without interruption. The default value is 120.
235 235
236 236 ipadm create-addr [-t] -T addrconf [-i interface-id] [-p
237 237 {stateful|stateless}={yes|no}]... addrobj
238 238 Create an auto-configured address on the specified IP interface.
239 239 This takes the following options:
240 240
241 241 -i,--interface-id
242 242 Specify the interface ID to be used.
243 243
244 244 -p,--prop
245 245 Specify which method of auto-configuration should be
246 246 used.
247 247
248 248 -t,--temporary
249 249 Temporary, not persistent across reboots.
250 250
251 251 ipadm down-addr [-t] addrobj

253 253 received.
254 254

256 256 Temporary, not persistent across reboots.
257 257

260 260 received.

275 275 Temporary, not persistent across reboots.
276 276
277 277 ipadm refresh-addr [-i] addrobj

279 279 address detection for static addresses.

283 283 lease on the address.
284 284
