You use the ipadm command to configure the majority of TCP/IP properties, also known as tunables. The ipadm command replaces the ndd command as the primary tool for setting tunables. For more information about these changes, see Comparing the ndd Command to the ipadm Command in Transitioning From Oracle Solaris 10 to Oracle Solaris 11.3.
TCP/IP properties can be either interface-based or global and properties can be applied to a specific interface or globally to all of the interfaces within a zone. Global properties can also have different values within different non-global zones. For a complete list of the supported protocol properties, see the ipadm(1M) man page.
Typically, the default values of the TCP/IP protocol suffice for the network to function. However, if these values are insufficient for your particular network topology, you can customize the properties by using the following three ipadm subcommands:
ipadm show-prop –p property protocol – Displays the properties of a protocol and its current values. If you do not use the –p property option, then all of the properties of the protocol are displayed. If you do not specify a protocol, then all of the properties of all of the protocols are displayed.
ipadm set-prop –p property=value protocol – Assigns a value to the protocol's property.
To assign multiple values to a protocol's property, use the following syntax:
ipadm set-prop [–t] –p property=value[,...] protocol
To remove one value from a set of values for a given property, use the -= qualifier:
ipadm set-prop –p property-=value2
Reset a specific protocol property to its default values as follows:
ipadm reset-prop –p property protocol
