HP-UX networking related tools and commands

As my journey continues to exploring HP-UX I found couple of nice utilities and tools to configure and administrate HP-UX networking subsystem.

    #ifconfig du2
    du2: flags=51
    inet 10.10.10.154 –> 121.1.1.1 netmask fffffff8

    #netstat -ni
    Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll
    du2 448 10.10.10.152 10.10.10.154 278603 0 281866 0 0

    #netstat -nrv
