Overview of Tuning IP Suite Parameters

You can set all of the tuning parameters described in this chapter by using the ipadm command except for the following parameters:

• ipcl_conn_hash_size

• ip_squeue_worker_wait

• ip_squeue_fanout

These parameters can only be set in the /etc/system file.

Use the following syntax to set TCP/IP parameters by using the ipadm command:

# ipadm set-prop -p parameter tcp|ip

For example:

# ipadm set-prop -p extra_priv_ports=1047 tcp
# ipadm show-prop -p extra_priv_ports tcp
PROTO PROPERTY              PERM CURRENT      PERSISTENT   DEFAULT      POSSIBLE
tcp   extra_priv_ports      rw   1047         1047         2049,4045    1-65535

For more information, see ipadm(1M).

Use the following syntax to set TCP/IP parameters by using the ndd command:

# ndd -set driver parameter

For more information, see ndd(1M).

Although the SMF framework provides a method for managing system services, ipadm commands are still included in system startup scripts. For more information on creating a startup script, see Using Run Control Scripts in System Administration Guide: Basic Administration.

IP Suite Parameter Validation

All parameters described in this section are checked to verify that they fall in the parameter range. The parameter's range is provided with the description for each parameter.
