Useful to read.
This is small book and I like small books.
Although it is small there is no shortage of information in book.
Book explains: what is Ethernet switch, for what is used, how it is working, VLAN (virtual LAN), STP (Spanning Tree Protocol), network design, different special purpose switches (like: multi-layer, access, industrial, wireless access point switch, ISP switch, data center switch) and advanced switch features (PoE, traffic flow monitoring).
Good read for getting advanced understanding of Ethernet switches.
