1 Article purpose[edit]

This article provides the basic information needed to start using the Linux kernel tool: ip [1].

2 Introduction[edit]

The following table provides a brief description of the tool, as well as its availability depending on the software packages:

Yes: this tool is either present (ready to use or to be activated), or can be integrated and activated on the software package.

No: this tool is not present and cannot be integrated, or it is present but cannot be activated on the software package.

3 Installing the trace and debug tool on your target board[edit]

3.1 Using the STM32MPU Embedded Software distribution[edit]

ip is installed by default (/sbin/ip) and is ready to be used with all STM32MPU software packages. 

 which ip
/sbin/ip

It is integrated into the Weston image distribution by using the following meta-st package recipie to enable the iproute2 module: meta-st/meta-st-openstlinux/recipes-st/packagegroups/packagegroup-framework-tools.bb. 

RDEPENDS_packagegroup-framework-tools-network-base = "\
   ethtool         \
   iproute2        \
   "

  • To assign an IP address to an interface
 ip addr add 192.168.1.53 dev eth0
  • To remove an IP adress
 ip addr del 192.168.1.53 dev eth0
  • To enable an interface
 ip link set eth0 up
  • To disable an interface
 ip link set eth0 down
  • To check a route table
 ip route show

  • To add a static route
 ip route add 10192.99168.02.0/16 via 192.168.1.1 dev eth0
  • To remove a static route
 ip route del 10192.99168.02.0/16
  • To set the default gateway
 ip route add default via 192.168.1.1
