Network question - using hubs to get more ports

in CCNA & CCENT
If I need 4 more network connections but only have one hot port can I use a 4 port hub to give me the extra network ports I need?
What type of issues could I run into, vlan?
This is for a lab at my work.

it should work fine. if the port is an access port it will strip the vlan tag off before it gets to the hub. shouldn't be any problems for a lab. -

Hub or switch? Big difference between the two.
If it is a switch, is it a managed switch?
If it is a managed switch, what brand is it? e.g. You'll get weird CDP output if your switch doesn't understand CDP. -

Just a hub.
So this won't affect the port speed? -

Save yourself the hassle and buy a switch. This one is $22.

Hub is a shared medium.... Due to this it has one collision domain for all hosts connected which means it must operate at half-duplex...
I'm pretty sure most hubs are 10Mbps\Half-duplex by default..... I've never come across a 100Mbps hub... but then again I've never tried to search for one.
Get yourself a cheap switch... if money is an issue... doesn't have to be manageable if you only need it to connect extra hosts. Gets around the half-duplex issue as each port has a seperate collision domain allowing for full-duplex operation to all hosts.
Just make sure whatever you uplink it too is configure as an access port.

SurferdudeHB,
Do you have 4 spare IP addresses within the subnet associated with the potential hub subnetwork? -

Um, you might want an actual Cisco switch if you are doing the CCNA
You can get a 2950-12 or 2950-24 for around $75 shipped these days -

I'm surprised that no one mentioned the obvious problem -- if it's not YOUR NETWORK and you aren't the Network Admin (or best buddies with them):SurferdudeHB wrote: »What type of issues could I run into
Best Case -- you lose your network connection if someone punks you by connecting 2 of your hub/switch ports with a crossover cable.
Worst Case -- Network Admin/Network Security hunts you down and kills you for adding an unauthorized device to the network.
But if it's an isolated lab network -- then you may just incur the wrath of whoever acts as the lab admin if something goes wrong
