Can you have multiple VLANs on one device?
Yes, you can put different subnets on the same nic, without even going into the VLAN territory. VLANs are a whole different beast and if all you need is to address different subnets, there is no reason to complicate things.
Can you have multiple VLANs on the same subnet?
It mostly depends if/how you want hosts on them to talk one another (or other networks). If the answer is “not at all” then you can have as many VLANs as you like using the same subnet.
Can a server be on multiple VLANs?
Although VLANs are commonly used to create individual broadcast domains and/or separate IP subnets, it can be useful for a server to have a presence on more than one VLAN simultaneously. Several Sun products support multiple VLANs on a per port or per interface basis, allowing very flexible network configurations.
Can an access point have multiple SSIDs?
In Multi-SSID mode, the access point creates multiple wireless networks to provide different security and VLAN groups. This mode is suitable when you want your devices connected to different wireless networks and become isolated by VLANs.
Can different VLANs have same network?
No, VLANs don’t require different subnets. Different subnets require different subnet addresses if they ever need to be able to route and/or talk to each other) and by extension if one VLAN wants to talk to a different VLAN it must use different addresses so we can make a routing decision to the right place.
Can you have a VLAN without a switch?
If your going to use vlans then yes you need a switch that supports vlans.. You don’t need a 1000 enterprise grade switch, unless you want one 😉 A port gig switch that understands vlans is like 30-35$ to start.. But if your going to create vlans – then yes your whole infrastructure needs to understand them..
Does each VLAN need its own router?
VLANs don’t need routers to communicate. Well, they usually do, but not necessarily. They just need some “external help”.
Should servers be on separate VLAN?
By security and network performance reasons the servers and users must not be on the same network and sharing switches either. The recommendation is always separate networks through VLANs it includes the server farm, the communication between VLANs will be accomplished if there is a Layer 3 devices.
How many is too many SSIDs?
3 SSIDs
No more than 3 SSIDs should be enabled on any single AP. Each SSID should have band-steering enabled. Legacy bit rates should be disabled on each SSID.
Is it better to have one SSID or two?
It’s highly dependent on your situation and requirements. If you are working with just a lone Wi-Fi router, then using the same SSID on both bands can help devices stay connected, especially in areas where 5 GHz can’t reach but 2.4 GHz can.
Can one VLAN talk to another?
For the Engineering computers to be on the same network across multiple building floors, VLANs are used to isolate this traffic from marketing and accounting computers. Devices in different VLANs cannot communicate when only using layer 2 switches.
Does a router care about VLANs?
In practice, your device usually doesn’t care about VLANs – it just sends the packet to the gateway. The gateway (i.e. the router) makes this decision the same way as it would decide between physical connections: based on subnets and routing tables.
Does each VLAN need its own switch?
Yes, you need to give each switch an IP in the management network. You don’t say which switches you’re using, but normally you assign an IP to a VLAN. So, if you’re using VLAN 99, one of the config lines under it would be “ip address 10.0.
Does each VLAN need an IP address?
As each VLAN is a different network, they need their own address subnet (IPv4 and IPv6). The Campus Core switch will route between each VLAN (so called L3-switch: an ethernet switch which has some L3 routing capability). These IP addresses are also documented in the master IP address plan.
How many VLAN can be created?
4096 VLANs
Creating a VLAN A switch supports a maximum of 4096 VLANs, among which VLANs 0 and 4095 are reserved for system use, and VLAN 1 is the default VLAN. Therefore, you can only create VLANs 2 to 4094.
