3.5.2.6.3. Test Procedure by Using Name Space Environment

Use the following script to create name spaces and execute the commands.

  1. Stop the network manager by using following command: 
    systemctl stop NetworkManager.service
  2. Create the name spaces: 
    ip netns add <VM name>
    For example: 
    ip netns add vm0
ip netns add vm1
ip netns add vm2
ip netns add vm3
  3. Assign the interface to name space:
    Command: 
    ip link set <interface> netns <namespace>
ip link set ifc_mcdma0 netns vm0
ip link set ifc_mcdma1 netns vm1                                                
ip link set ifc_mcdma2 netns vm2
ip link set ifc_mcdma3 netns vm3
  4. Bring up the interface:

    Command: ip netns exec vm0 ifconfig <interface> up

    Example: 
    ip netns exec vm0 ifconfig ifc_mcdma0 up
ip netns exec vm1 ifconfig ifc_mcdma1 up
ip netns exec vm2 ifconfig ifc_mcdma2 up
ip netns exec vm3 ifconfig ifc_mcdma3 up
  5. Assigning the IP address:

    Command: ip netns exec <namespace> ip addr add <ipaddr> dev <interfacename>

    Example: 
    ip netns exec vm1 ip addr add 1.1.1.11/24 dev ifc_mcdma1
ip netns exec vm0 ip addr add 1.1.1.10/24 dev ifc_mcdma0
ip netns exec vm2 ip addr add 1.1.1.12/24 dev ifc_mcdma2
ip netns exec vm3 ip addr add 1.1.1.13/24 dev ifc_mcdma3
  6. Ping from one interface to another interface:
    Command: ip netns exec <namespace> ping <ip address>
    Example: 
    ip netns exec ifc_mcdma0 ping 1.1.1.11

  7. Use iperf and netperf applications to test the TCP and UDP traffic.
  8. Execute the following command from the host:

    Execute the following command to run iperf server: 

    $ip netns exec vm1 bash  
$iperf -s

    Execute the following command to run iperf client: 

    $ip netns exec vm0 bash
$iperf -c 1.1.1.10 -i 10 -l 64
