Connecting Open vSwitch running on Debian to Cisco Catalyst 3550 via trunk

In a previous tutorial we showed how to install Openvswitch on Debian Linux. At the end of tutorial we created a script that loads openvswitch module in to the Linux kernel, starts and initializes configuration database and starts daemon ovs-vswitchd. In this tutorial we will connect our Openvswitch to Cisco Catalyst 3550 switch via 802.1q trunk. […]

Openvswitch Installation on Debian

OpenvSwitch is a production quality open source software switch designed to be used as a vswitch in virtualized serverenvironments. A vswitch forwards traffic between different VMs on the same physical host and also forwards traffic between VMs and the physical network. Open vSwitch supports standard management interfaces (e.g. sFlow, NetFlow, IPFIX, RSPAN, CLI), and is […]

OPENVSWITCH - Playing with Bonding on Openvswitch

Bonding is aggregation multiple links to single link in order to increase throughput and achieve redundancy in case one of links fails.  From what I know about bonding, they are two possibilities to configure it. The first option is to load bonding module to kernel and use ifenslave utility for its configuration. Configuration steps for […]

OPENVSWICH – Campus Model with Layer2 Access built with Open-Source Applications

In the first tutorial we showed how to create Openvswitch extension and submit it to Tinycore repository. There were also presented after-install steps for Openvswitch adapted for specific Core needs. In a previous tutorial we performed several tests in order to test configuration such as vlans, 8021q trunks and VLAN interfaces widely used in typical multilayer switches. In this tutorial […]

OPENVSWICH - Creating and Submitting Openvswitch Extension To Tinycore Repository

In May 2011, I read a request for installation Openvswitch on Qemu image. I started to play with Openvswitch and finally became fan of this project. I soon realized how powerful can be Openvswitch, offering many features so far available only in hardware switches. After several days spent with playing with Core Linux and Openvswitch I was […]

OPENVSWICH - VLANs, Trunks, L3 VLAN interface, InterVLAN Routing - Configuration And Testing

In a previous tutorial we showed how to install Openvswitch on Qemu image with Microcore Linux. At the end of tutorial we created Openvswitch extension and submitted it to Microcore public repository. Assuming that Openvswitch is configured and functional, we are ready to make three labs which  helps us to test features such as VLANs, trunks […]
