Cisco has released an IOS-XE version that work in VMware and KVM. The one that are likely not to work are 元 Etherchannel, ISL trunks, DHCP snooping, Private VLAN, SPAN/RSPAN/ERSPAN, Port-security, Voice VLANs, MLS QoS and QinQ.Ī. Simply because L2IOU images do not support all of the features, we suspect that some of them require the dedicate hardware found in Cisco devices in order to work, other features are simply buggy in currently available L2IOU versions. Why not supporting 100% of Cisco switching features?Ī. On Windows and Mac OS X, the current plan is to use a virtual machine to run L2IOU but we are still looking for an alternative technical solution. Currently, L2IOU images work only on Linux or Solaris. Will switching work on Windows or Mac OS X?Ī. So in the end you can have 90% of the same features, just a bit slower. These are more like generic Cisco switches with most of the same features as in real switches. Switching is going be supported in GNS3 using L2IOU images, which are special IOS images made to work on PC/Linux.
