every switch port is collision domain ,,, in order to break broadcast domain Simply create Vlans, every Vlan is broadcast domain on the switch
Create VLANs to control broadcast domains
By Creating VLAN on Layer2 Switch You Can Create Multiple Broadcast Domain But the Switch Has To Managed Switch Like CISCO
Simply VLAN- or Virtual LAN will solve this
All the broadcast issues can solve through VLAN but your switch should be manageable switch
By creating VLANs !
Every VLAN you create, makes a separate broadcast domain.
Hi
Switches can segment broadcast domains by using VLANs. VLANs create separate broadcast domains running on the same physical hardware.
Normally you would not want to do that. Broadcast are needed for proper IP connectivity as it is used by ARP. If you split broadcast domains you are breaking your networks down into IP subnets.
Some switches can offer broadcast/multicast storm control features which in my opinion would basically throttle the amount of traffic created by broadcasts. This will help you avoid DOS attacks causing network resources depletion (bandwidth and switch memory).
The main question is why do you have problems with broadcasts to begin with. If you have good control over the IT infrastructure you would expect that your clients (and I hope servers) would be trusted. However if you operate a public access network that is another story. VLANs & Subnets can be a solution here.
Ultimately the best place to protect your network is the edge. Gain control over your clients, use network admission control mechanisms that perform host checks (but those are rather pricey)
Cheers
Switches will not control the broadcast domain by default until implement the segmentation.Creating vlans in a manageable switch will help you to create multiple broadcast domains in a single switch and assigning port vlan membership will help you to control the each broadcast domains.
I think its not possible using normal-layer2-switch (i.e. switch that doesn't support routing functions) as you need a router or a layer3 switch to break the domain. bottom line you need to have a layer3 device to achieve that
dividing the broadcast domains on the switch done by using VLAN
By using the VLANs configuration.
