  # traceroute -i lan2 

HP-UX stores network interface configuration information on /etc/rc.config.d/netconf file

  # cat /etc/rc.config.d/netconf  HOSTNAME="it-hp49"  OPERATING_SYSTEM=HP-UX  LOOPBACK_ADDRESS=  INTERFACE_NAME[0]="lan0"  IP_ADDRESS[0]=""  SUBNET_MASK[0]="0xffffff00"  BROADCAST_ADDRESS[0]=""  INTERFACE_STATE[0]=""  DHCP_ENABLE[0]=0   ROUTE_DESTINATION[0]="default"  ROUTE_MASK[0]=""  ROUTE_GATEWAY[0]=""  ROUTE_COUNT[0]="1"  ROUTE_ARGS[0]=""

To add a alias address to lan0, add the network information to /etc/rc.config.d/netconf file


Restart the network service

  /sbin/init.d/net start
