The TCPIP OPTION (OPT) command enables you to configure TCP/IP options to control various network features. This subsection describes the tasks you can perform using this command.
Some of these options can be turned on and off to enable or disable the option by entering the OPTION command in the following format:
NW TCPIP OPT <+/–> <option>
where <+> turns on the specified option and <-> turns off the specified option.
For other options you must specify a value in the following format:
NW TCPIP OPT <option> = <value>
Note: | The default values for these options are set in accordance with related Internet specifications, and should not be changed unless directed by Unisys support engineers. |
Options can be turned on or off all at once with the ALL option, or individually, separated by commas. If you specify an option without a trailing option string, an inquiry is initiated on the current setting of each option.
Note: | The ALL option does not apply to the IPsec, SSL, IPDESTADDR, and RESTRICTOFFPORT options. |
Refer to the Networking Commands and Inquiries Help for information about command syntax.
