Can you have multiple subnets on same switch?

You can use the same switch for multiple subnets, but you need to you VLAN’s that is what they are there for, unless you switch won’t support VLAN’s. First time your switch gets a MAC address back that has an IP addresses in more than one subnet it’s gonna freak out.

Can multiple subnets be on same VLAN?

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.

What is IPsec conf?

The ipsec. conf file specifies most configuration and control information for the Libreswan IPsec subsystem. conf is a text file, consisting of one or more sections. White space followed by # followed by anything to the end of the line is a comment and is ignored, as are empty lines that are not within a section.

Can you run 2 networks on the same switch?

VLANs allows us to take a single physical switch and logically group ports into multiple smaller switches. Each smaller group would be a VLAN. This is no the only configuration though. A single VLAN can also span multiple switches to regroup ports from multiple switches to work as a single switch.

CAN devices on different VLANs see each other?

VLANs are a way to break up networks into easily-manageable chunks of about 100-or-so devices. Devices in different VLANs can still communicate with each other, via a router (which can be a router, Layer3 switch or firewall).

Can 2 VLANs have the same IP range?

The OSA-Express Layer 2 implementation allows the hosts to manage IP addresses and ARP cache, so it is possible to have a single guest LAN segment (or VSWITCH segment) where two different hosts use the same IP Address on different VLAN groups. …

Can a switch have multiple IP addresses?

But since the switch does not have the capability to assign IP addresses, the computers connected to it will not be able to communicate with each other. They will get an Automatic Private IP Address (APIPA). You need to assign a static IP address to your computers.

What is left and right in IPSec?

Note: In IPsec parlance, “Left” always refers to the device you are currently configuring, and “Right” refers to the device at the other end of the tunnel.

Is IPSec more secure than OpenVPN?

Open VPN – In terms of security, OpenVPN is far most the best protocol. It does have a proper implementation and very less number of vulnerabilities. IKEv2/IPSec – IKEv2 protocol is considered to be more secure and reliable. In fact it is one of the popular choices for the VPN users.

How do I switch between two networks?

The idea is to put your two “input” ports on two separate VLANs, and plug your two networks into those ports. Plug the device you wish to swap between networks into a third port on the switch, and then configure that port to reside on whichever VLAN you wish.

Do switches separate networks?

While switches allow different devices on a network to communicate, routers allow different networks to communicate. A router is a networking device that routes data packets between computer networks. A router can connect networked computers to the Internet, so multiple users can share a connection.

Can a device be on 2 VLANs?

A vlan is not a network. You can have multiple networks on a single wire. You can have a single network on multiple wires – you can’t route between them, but you can move traffic. Every switch port is a collision domain.

Can a switch connect to two different subnets?

If host A and B are on different networks or subnets and connected to the same switch I believe that they can communicate through the default gateway. Only if the switch is connected to a router that knows how to route between these 2 subnets. Thanks for contributing an answer to Network Engineering Stack Exchange!

Can a subnet be connected to multiple VLANs?

You could use one subnet per VLAN to create multiple broadcast domain for multiple ip ranges. And if you want to communication between those virtually separated vlans (ip address ranges) within a switch, use Router on stick and configue trunck to interface which is connected between Router n switch.

Can a switch be used as a hub?

No, because a switch is not a hub. A switch sends unicast packets only to those ports that have the receiving MAC address registered. •Do you see any problems with this aside from how confusing it is, and that it would put one switch doing the work of two subnets?

How to communicate between VLANs within a switch?

And if you want to communication between those virtually separated vlans (ip address ranges) within a switch, use Router on stick and configue trunck to interface which is connected between Router n switch. Thanks for contributing an answer to Server Fault!
