How to Configure IOSv-L2 on GNS3 for Advance Switching

While an Etherswitch module does not support advanced layer 2 features, it does allow you to configure basic VLANs, Spanning Tree and other options.  Now you can learn more advanced switching  technologies using Cisco IOSv-L2 VM. Like Etherchannel, , Port Security, DTP, HSRP, Layer-2 forwarding, Switchport, 802.1q trunk, 802.1q VLANs, Spanning Tree (PVST+, RPVST+, MST), Port-Channel (Pagp and Lacp), 802.1x passthrough, Port-ACLs, Dynamic Arp Inspection, DHCP Snooping, IP device tracking, Switched Virtual Interfaces, Layer-3 forwarding over SVIs, Routing protocol support (ISIS is NOT supported), VTP v1-3, PVST, QoS, Inter-VLAN routing, VLAN Access Maps (VACLs / access control lists for VLANs), ACL functionality for both layer2 and layer3 protocol packets, Dynamic Trunking Protocol support, Switchport protected mode And many others.
Port mirroring (SPAN) and Private VLANs are NOT currently supported.
