Linksys LGS308 is a "smart" gigabit networking switch with a administration GUI where basic network settings can be configured. It supports channel bonding, VLANs and all the usual features managed switches have.
It's got everything you'd expect from a 8-port network switch. It supports VLANs, STP, Mac address management, multicast, bonding ("link aggregation") and everything else you may want from a 8-port switch. Bonding works fine with standard Linux bond0 devices; configuring it is trivial if you have any two gigabit-capable network cards in a machine.
All 8 ports are standard gigabit copper ports, there is no SPF+ ports or 10-gigabit ports.
It's fine. There's never been an issue after more than a year of constant use with 2 bonds of 2 ports each.
This switch is a good choice if you need a 8-port smart switch and the price is right. This particular switch has been priced all over the place; it's a fine switch but it isn't worth paying 2x the price of any other 8-port smart switch.
The LGS308 defaults to admin as both username and password.
