Typical I bought the 5 for the other day lol. Don’t need 8 but would’ve bought it for same price
Good when they're metal ... Plus remember you always "lose" one port for the input. The only bad thing about these is that they dont do Power over ethernet ,
Good price for a switch to be part of a kit bag

What do you need 5 switches for?

if you want power over ethernet you're not going buy a £15-20 switch lol. These ant designed for that.
Nice, this reminds me of when I started working in IT back in 2002 🙈
So I wondered if there is a cost (performance) associated with daisy chaining switches?

Of course, if you daisy-chain these you're limited to 1Gb/s total between switch A and switch B. Whereas everything connected to a single switch can transfer at full speed to everything else simultaneously because the internal switching capacity is 10Gb/s.

Probably never going to bother you on a small home network.
I'd always get the Netgear ProSafe ones over these, they are only a pound or two more and rock solid in my experience.

Fair point I wasn’t sure the internal transfer speed... as you say for my home use case gigabit will do me.
Though missing that 24 port managed for £50 was a bummer.

I don’t as I’m only using one or two but was same price as 8.
I’ve just gone down the route of plugging Xbox and Apple TV into Ethernet rather than WiFi.
Also got a bridge for hue and one for Tado and also sonos

Where in the spec does it say this switch does line rate switching?

Would be surprised if this can handle line rate switching.

I think the short answer is "for home networks, no, there isn't".

Also there is 2Gbps between switch A and B as it's full duplex.

The 10Gbps switching is a result of each of the 5 ports being able to do 2Gbps each, so yes they are line rate.

For big networks these small switches are dreadful.
They have tiny buffers enough to store and forward a jumbo frame at a time as a result they cause all sorts of framing issues for multiple concurrent large transfers and they have tiny MAC tables which ends in them turning into a hub and crashing alot.
Wish I bought the 16 port one now..

That's yet another thing I've had to look up - I was blissfully unaware of poe until now - thankfully I don't need it - phew.

You seem knowledged.. I'm only half knowledged on it as I've USUALLY had four ports - tell me, should I run this through my providers router to get more ports and run at the same speed? Or am I better to plug in my other router which seems to do the same tricks? I've been meaning to swap it for a while but the level of farting about goes beyond what I can be bothered doing and everything but the PC and console is running wireless haha.

I don't know too much about ethernet and networks lol i just know that Power Over Ethernet requires a more expensive switch. Honestly, i think you're best using your other router since you already have it. If you turn off the wifi function then it will basically just be a simple modem. Though this switch will be worth getting if your router doesn't have gigabit ethernet ports.

The other router is set for ADSL or cable and like the NowTV router (well.. Sky, it's the same one..) it supports both WiFi bands.. but has four rather than two outs and as much as I've had it a few years, it's more than capable of running home interwebs since out here "super fast" means 38mbit top speed haha.. chancers.. I got it discounted to medium speed and got free telly with it and it was half the price of the rest for said reasons.. too much info but aye, I'll likely just set the other one up haha.. four consoles, telly and PC.. it's a shame WiFi isn't anywhere near stable enough to game on
Word of advice, go for the 8 port over the 5, as you lose a port to your router and you might not need the extra port now, but at some point you'll find yourself a port short.. (as I did)

turns it into a hub? no. Hub = layer 1 .. switch = layer 2.

When MAC tables (called a CAM table on the ASIC) fill in a switch it broadcasts instead, which is what a hub does, also used maliciously by attackers to find all devices on a network.

Smaller the table, more likely to broadcast everything.
