Hi all,
I am trying to implement vlan in mininet open vSwitch. I did the following ..
Open vSwitch version : 1.9
Kernel version : 3.8.0-19-generic
1. Create a topology using sudo mn command as,
mininet@mininet-vm:~$ sudo mn --topo=linear,2
*** Creating network
*** Adding controller
*** Adding hosts:
h1 h2
*** Adding switches:
s1 s2
*** Adding links:
(h1, s1) (h2, s2) (s1, s2)
*** Configuring hosts
h1 h2
*** Starting controller
*** Starting 2 switches
s1 s2
*** Starting CLI:
mininet>
2. Topology is as
mininet> net
h1 h1-eth0:s1-eth1
h2 h2-eth0:s2-eth1
s1 lo: s1-eth1:h1-eth0 s1-eth2:s2-eth2
s2 lo: s2-eth1:h2-eth0 s2-eth2:s1-eth2
c0
mininet>
3. I tagged s1-eth1 & s2-eth1 port as access port And s1-eth2 & s2-eth2
as trunk port with same vlan 1d 20.
mininet@mininet-vm:~$ sudo ovs-vsctl set port s2-eth2 trunk=20 vlan_mode=trunk
mininet@mininet-vm:~$ sudo ovs-vsctl set port s1-eth2 trunk=20 vlan_mode=trunk
mininet@mininet-vm:~$ sudo ovs-vsctl set port s1-eth1 tag=20 vlan_mode=access
mininet@mininet-vm:~$ sudo ovs-vsctl set port s2-eth1 tag=20 vlan_mode=access
4.
mininet@mininet-vm:~$ sudo ovs-vsctl show
fc881c5c-41dd-4904-91e9-591c7a851011
Bridge "s2"
Controller "ptcp:6635"
Controller "tcp:127.0.0.1:6633"
is_connected: true
fail_mode: secure
Port "s2-eth1"
tag: 20
Interface "s2-eth1"
Port "s2"
Interface "s2"
type: internal
Port "s2-eth2"
trunks: [20]
Interface "s2-eth2"
Bridge "s1"
Controller "ptcp:6634"
Controller "tcp:127.0.0.1:6633"
is_connected: true
fail_mode: secure
Port "s1"
Interface "s1"
type: internal
Port "s1-eth1"
tag: 20
Interface "s1-eth1"
Port "s1-eth2"
trunks: [20]
Interface "s1-eth2"
ovs_version: "1.9.0"
mininet@mininet-vm:~$
5. Now I pinged h1 ping h2.
mininet> h1 ping h2
PING 10.0.0.2 (10.0.0.2) 56(84) bytes of data.
64 bytes from 10.0.0.2: icmp_req=1 ttl=64 time=23.9 ms
64 bytes from 10.0.0.2: icmp_req=2 ttl=64 time=0.581 ms
^C
--- 10.0.0.2 ping statistics ---
2 packets transmitted, 2 received, 0% packet loss, time 1003ms
rtt min/av
ping is working here. But vlan is not tagged in the wireshark log.
And also tagging is not working as I tried with s1-eth1(h1) tag with vlan 10
and s2-eth1(h2) with vlan 20 . ping works in this configuration.
Thanks
