Can 2 VLANs Have The Same IP Range?

Can VLAN see each other?

OK so I hope I explain this correctly.

The issue is that None of the IP phones can ping the computers and vice versa.

The reason the phones are on the seperate internet connection is so that if we eat all the bandwidth on the EdgeMAX which only have like 20MBPS it doesn’t degrade the phones..

Are VLANs more secure?

Because VLANs support a logical grouping of network devices, they reduce broadcast traffic and allow more control in implementing security policies. Also, surveillance traffic is only available to those authorized, and bandwidth is always available, when needed.

Do VLANs have different IP addresses?

VLANs do not really have IP addresses assigned to them. They have a network assigned to them, or a subnet, or a network range, however you want to refer to it. The address the OP supplied us is an assignable address within the range of 192.168. 4.1-255.

The simplest way to enable routing between the two VLANs to simply connect an additional port from each VLAN into a Router. The Router doesn’t know that it has two connections to the same switch — nor does it need to. The Router operates like normal when routing packets between two networks.

Can two VLANs talk to each other?

2 Answers. Two separate VLANs must communicate through a layer-3 device, like a router. Devices on a VLAN communicate with each other using layer-2. Layer-3 must be used to communicate between separate layer-2 domains.

How do I add multiple VLANs to a trunk port?

perform these steps:To restrict the traffic that a trunk carries, issue the switchport trunk vlan-list interface configuration command. … To add a VLAN to the trunk, issue the switchport trunk allowed vlan add vlan-list command.This example shows how to remove VLANs 5 through 10 and 12.

What is the highest VLAN number?

4,094Under IEEE 802.1Q, the maximum number of VLANs on a given Ethernet network is 4,094 (4,096 values provided by the 12-bit VID field minus reserved values at each end of the range, 0 and 4,095).

How many VLANs can you have?

In total there can be 4096 VLANs. Among these, VLAN 1 is default; this means all the untagged traffic would move from here. VLAN 1002–1005 are reserved for token ring.

What is difference between trunk and access port?

Understanding Access and Trunk Interfaces An access port can have only one VLAN configured on the interface; it can carry traffic for only one VLAN. A trunk port can have two or more VLANs configured on the interface; it can carry traffic for several VLANs simultaneously.

How do I know my VLAN?

To find your VLAN (on a Windows XP machine), go to “Start Menu”,then click the return (enter) key on your keyboard. This runs a command prompt. Type in “ipconfig” and hit return again. You will see your IP Address, your Subnet Mask and your Default Gateway.

Can 2 VLANs have the same subnet?

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.

How many VLANs should I have?

If you’ve got traffic that has to be prioritized(like VOIP, or Storage) than put that traffic in one VLAN. Your Users(and Printers) can be in one VLAN, or because of the amount I would make 2-3 VLANs; if there are security reasons to separate a certain department or group of users, than take them out of the User VLAN.

Do VLANs slow networks?

Each network has its own broadcast domain. … As the amount of traffic grows, these broadcast packets can congest the network and could potentially slow things down. Splitting the traffic into two networks created by VLANs can greatly reduce the broadcast traffic and reduce congestion on the network.

Should printers be on their own VLAN?

The printer server usually doesn’t need to be on the same VLAN as the printers since it doesn’t need to speak with them using layer 2 but connects using TCP/IP. So you can keep it in the servers VLAN. … If your switches have IP routing turned on, then you MUST put ACL’s on the switches.

Can one port have multiple VLANs?

4 Answers. If you want to use a port as an access-port, only one VLAN can be assigned to this port. If you want to use a port as a trunk though, all VLANs which can be handled by the switch can be “assigned” (You don’t need to assign VLANs to a trunk because per default, it will handle every VLAN).

Can we assign 2 VLANs to a single port?

The answer is yes, but it depends on what you’re trying to do. There are 2 types of ports when it comes to Vlans: Trunk ports and Access Ports. Trunk ports are designed to move data on multiple Vlans between switches and routers.

Can a Layer 2 switch route VLANs?

Layer 2 switches can only route packets between different subnets or VLANs if the two MAC addresses are both PHYSICALLY connected to the layer 2 switch and.

Can VLANs be hacked?

VLAN is based on Layer 2 “Data link” of the OSI Model. The OSI layers are independent of each other and they communicate with each other. If any one of the layer gets compromised the other layers also fail. The VLAN is on the Data Link layer, which is as vulnerable to attacks as any other layer on the OSI model.
