Network Configuration and Administration Commands (Quick Reference)

The following table describes the commands that are used to manage network configuration in both fixed and reactive mode.

Note - Starting with Oracle Solaris 11.1, you can use fixed networking commands to manage reactive NCPs, provided that the NCP is currently active. The command usage in the following table reflects this change.

Table 7-2 Commands That Are Used to Configure and Administer the Network

Configuration/Administration Task	Commands to Use in Reactive Mode	Commands to Use in Fixed Mode
Switch network configuration modes (enable or disable an NCP or a Location profile).	Enable the `Automatic` NCP: `netadm enable -p ncp Automatic` Enable any reactive NCP: `netadm enable` `-p` `ncp` `ncp-name` Enable a Location: `netadm enable -p loc` `loc-name`	Enable the `DefaultFixed` NCP: `netadm enable -p ncp DefaultFixed`
List the status of all network profiles on a system.	`netadm list`	`netadm list`
Configure link properties.	`netcfg "create ncp` `ncp-name`; `create ncu phys` `ncu-name`; set `property`=`value`”	`dladm set-linkprop` `-p` `property`= `value` `link`
Configure IP interfaces.	`netcfg "create ncp` `ncp-name`; `create ncu ip` `ncu-name`; set `property`=`value`”	`ipadm create-ip` `interface`
Configure IP addresses.	Static IP: `netcfg "select ncp` `ncp-name`; `select ncu ip` `ncu-name`; `set ipv4–addrsrc=static; set ipv4–addr=1.1.1.1/24"` DHCP: `netcfg "create ncp` `ncp-name`; `create ncu ip` `ncu-name`; `set ipv4–addrsrc=dhcp"`	IPv4 or IPv6 static address: `ipadm create-addr -T static -a IP-address address-object` IPv4 DHCP address: `ipadm create-addr` `-T` `dhcp` `address-object` Auto-generated IPv6 address based on a system's MAC address: `ipadm create-addr -T addrconf address-object`
Set the `netmask` property.	For the `Automatic` NCP: The DHCP server assigns the `netmask` property. For other reactive NCPs: This property is set by using the `netcfg` command and is assigned as part of the static IP address. To assign the property, append the end of the IP address with `address`/`prefixlen` (`192.168.1.1/24`). View the `netmask` property: `ipadm show-addr`	This property is set by using the `ipadm` command, as part of the static IP address assignment. To assign the property, append the end of the IP address with `address`/`prefixlen` (`192.168.1.1/24`). See How to Configure an IP Interface in Oracle Solaris Administration: Network Interfaces and Network Virtualization. View the `netmask` property: `ipadm show-addr`
Modify existing network configuration.	Configure link properties: `netcfg "select ncp` `ncp-name`; `select ncu phys` `ncu-name`; set `property`=`value`” Configure an IP interface: `netcfg "select ncp` `ncp-name`; `select ncu ip` `ncu-name`; set `property`=`value`”	`dladm set-linkprop -p` `property`=`value` `link` `ipadm set-prop` [`-t`] `-p prop=value[,...`] `protocol` `ipadm set-addrprop` [`-t`] `—p prop`=`value`[`,...`] `addrob`j `ipadm set-ifprop -p` `property`=`value` `interface` `ipadm set-prop` `-p` `property=value` `-m` `protocol interface` `ipadm set-addrprop -p` `property=value addrobj`
Configure or modify naming services (NIS and DNS).	Configure DNS from DHCP: `netcfg "create loc` `loc-name` ; `set dns-nameservice-configsrc=dhcp"` Manually configure DNS: `netcfg "create loc` `loc-name`; `set dns-nameservice-configsr=static`; `set dns-nameservice-servers=1.1.1.1`; `set dns-nameservice-search=foo.com"` For an existing Location: `netcfg "select..."`	Set parameters for naming services: `svccfg` and `svcadm`
Configure LDAP.	Only LDAP anonymous mode works when in reactive mode. To use an LDAP proxy or LDAP self-modes, enable the `DefaultFixed` NCP.	`ldapclient` or SMF commands to select LDAP.
Configure default route.	For any reactive NCP: `netcfg "select ncp` `ncp-name`; `select ncu ip` `ncu-name`; `set ipv4–default-route=1.1.1.1"` Persistently set a default route: `route -p add default` `routerIP-address`	Persistently set a default route: `route -p add default` `routerIP-address` Set any persistent route: `route -p add -net` `nIP-address` `-gateway` `gIP-address`
Display default route.	`netstat` `-rn` displays all of the active routes currently in use by the kernel, regardless of how the route was configured For any reactive NCP configured with a single, per-interface default route: `netcfg "select ncp` `ncp-name`; `select ncu ip` `ncu-name`; `get ipv4–default-route"` `route` `-p` `show` displays all of the static routes that are associated with the currently active NCP, if it was added with the `route` `-p` `add` command	`netstat` `-rn` displays all of the active routes currently in use by the kernel, regardless of how the route was configured `route` `-p` `show` displays all of the static routes that are associated with the currently active NCP, if it was added with the `route` `-p` `add` command
Configure host name (nodename).	When the `Automatic` NCP is enabled, the SMF service property is only set if the DHCP server does not provide a value for the nodename/hostname option (DHCP standard option code 12). See `nodename`(4)	Oracle Solaris 11: `svccfg` `-s` sets the `config/nodename` property of the `svc:system/identity:node` SMF service to the desired name. Oracle Solaris 11.1: Use the `hostname` command. See `hostname`(1).
Import naming service configuration.	Configured in the Locations profile.	`/usr/sbin/nscfg import -f FMRI` `nsccfg` exports existing legacy files into the SMF repository.
Unconfigure and reconfigure a system (including all network configuration).	Unconfigure an Oracle Solaris instance: `sysconfig unconfigure system` Reconfigure an Oracle Solaris instance: `sysconfig configure system`
