z/VM and Linux on IBM Z Networking


In this presentation, Malcolm will introduce a basic virtualised ethernet configuration using the z/VM VSWITCH (virtual switch) and then gradually enhance it to configure VLANs, authorisation, High Availability, Link Aggregation and a cross-LPAR LAG port group with Global VSWITCH. This will include covering more recent z/VM enhancements such as Directory Network Authorisation (DNA) and the Network Security Enhancements that do away with the distinction between User Based and Port Based VSWITCHes.
