Name:
        oifcfg - Oracle Interface Configuration Tool.

Usage:  oifcfg iflist [-p [-n]]
        oifcfg setif {-node <nodename> | -global} {<if_name>/<subnet>:<if_type>}...
        oifcfg getif [-node <nodename> | -global] [ -if <if_name>[/<subnet>] [-type <if_type>] ]
        oifcfg delif [{-node <nodename> | -global} [<if_name>[/<subnet>]]]
        oifcfg [-help]

        <nodename> - name of the host, as known to a communications network
        <if_name>  - name by which the interface is configured in the system
        <subnet>   - subnet address of the interface
        <if_type>  - type of the interface { cluster_interconnect | public }
