Why would a switch need to be configured with a default gateway?

The default gateway is required when a router is needed for tasks such as reaching off-subnet destinations or forwarding traffic across multiple VLANs. The gateway value is the IP address of the next-hop gateway node for the switch, which is used if the requested destination address is not on a local subnet/VLAN.

What happens if you do not configure a default gateway on your switch?

Long explanation: The default gateway on a switch has the same function as any gateway configured on a host PC. Without a default gateway, the switch management address (on VLAN 1 in your case, but it could be on any VLAN configured on the switch) cannot send traffic off its network to another network.

Is a default gateway always required?

You don’t have to have a default gateway. If no router exists on your network, you want to NOT specify one. In the Windows configuration for a network adapter you can leave the default gateway blank.

What happens if you don’t have a default gateway?

Originally Answered: What Happens If I Don’t Have a Default Gateway? If you don’t have it in your LAN, you will be able to communicate with other devices in the same lan through the power of switching. Downside of it is that you won’t be able to communicate with anyone outside your local network.

Is the default gateway the same as the IP address?

Yes, the default gateway IS an IP address, the IP address of your router. When a computer needs to reach another that resides on a network that is different from the one it is on it needs to know where to send or ROUTE the packets. The gateway is also called the Next Hop in routing terms.

Does a vLan need a default gateway?

on the same vLan they should not need a default gateway, if you wanted to ping say from 192.168. 3.100 to 192.168. 5.100 you would need to set the default gateway as the core/L3 switch.

When would you use IP default gateway on a switch?

The switch should be configured with a default gateway if the switch will be managed remotely from networks not directly connected. The default gateway is the first Layer 3 device (such as a router) on the same management VLAN network to which the switch connects.

How do I access my router without a default gateway?

How to Set Up a Router Without a Gateway Address

1. Launch your computer’s Web browser and type your router’s IP address into the address bar.
2. Click the “Settings,” “Basic Settings” or “Options” tab, depending on your make and model of router, to open the router’s IP address and gateway-configurations page.

Why do I have two default gateway?

More information Windows NT computers can be configured with multiple default gateways. This switch can occur when there are multiple gateways configured for the same network adapter or when different default gateway addresses are given on various network cards on a multihomed computer.

How to configure a Cisco switch?

Connect the switch to PuTTY with a 9-pin serial cable.

Now open PuTTY and the PuTTY Configuration window will display. Go to the Connection type settings and check the Serial option (shown below).

Go to the Category list section on the left-hand side and select the Serial option.

When the options controlling local serial lines page displays enter the COM port your network is connected to in the Serial line to connect to box

Next, enter the digital transmission speed of your switch model. For 300 and 500 Series Managed Switches, this is 115200.

Does a switch always need a default gateway?

A default gateway is used by all devices that require the use of a router to determine the best path to a remote destination. End devices require default gateway addresses, but so do intermediate devices, such as the Cisco IOS switch. The IP address information on a switch is only necessary to manage the switch remotely.

Why does a switch need a default gateway?

The short answer is that a default gateway typically is used to direct traffic destined for a “foreign” network (i.e. a network other than the one to which the switch belongs) off the switch to a “gateway” device on the same network as the switch. A switch that does not perform routing will use a default gateway.

How do you set the default gateway on a switch?

Resolution. To define a default gateway when IP routing is disabled, issue the ip default-gateway global configuration command. Then, enter the IP address of the next-hop router interface that is directly connected to the switch where a default gateway is being configured. The default gateway receives IP packets with unresolved destination IP…
