What layer is a router?
Network LayerA router works at Layer 3 of the OSI model – the Network Layer.
This is the layer that the IP protocol works at..
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.
How do I ping my router to switch?
To send the router a friendly ping, follow these steps:From the Start menu, choose All Programs→Accessories→Command Prompt. … To discover the router’s address, type ipconfig and press Enter. … Type the command ping, a space, and then the IP address of the router, or default gateway; press Enter.More items…
Does a switch have a MAC address?
Like all Ethernet interfaces, every port on a switch has a unique factory-assigned MAC address. However, unlike a normal Ethernet device that accepts only frames addressed directed to it, the Ethernet interface located in each port of a switch runs in promiscuous mode.
Is a switch layer 2 or 3?
The main difference between Layer 2 and Layer 3 is the routing function. … That means, a Layer 3 switch has both MAC address table and IP routing table, and handles intra-VLAN communication and packets routing between different VLANs as well. A switch that adds only static routing is known as a Layer 2+ or Layer 3 Lite.
What is a Layer 3 VLAN?
In an interview I have been asked “What is Layer 2 and Layer 3 VLAN “. I answered them, Layer 2 VLAN is a single broadcast domain. It works on layer 2 (Datalink Layer). They can communicate only within it. And L3 VLAN is an Interface, that works on Network Layer.
Do Cisco switches have IP addresses?
By default, Cisco switches forward Ethernet frames without any configuration. … However, to perform switch management over the network or use protocols such as SNMP, the switch will need to have an IP address. The IP address is configured under a logical interface, known as the management domain or VLAN.
Is a VLAN Layer 2 or 3?
VLANs are data link layer (OSI layer 2) constructs, analogous to Internet Protocol (IP) subnets, which are network layer (OSI layer 3) constructs. In an environment employing VLANs, a one-to-one relationship often exists between VLANs and IP subnets, although it is possible to have multiple subnets on one VLAN.
Can you ping from a layer 2 switch?
The reason that you can ping the L2 switch from a workstation of 10.0. … The default gateway on your L2 switch needs to be on the same network as the IP address. If your L2 switch has an IP address of 10.0.
Does a switch have an IP?
A unmanaged switch does not have an IP address. It is a ethernet switch and it switches ethernet packets and on the level of ethernet packets there are no IP addresses. … The switch is only the mean to connect three or more devices.
Is a Layer 3 switch a router?
A layer 3 switch is both a switch and a router: it can be regarded as a router with multiple Ethernet ports and with switching function. … Layer 3 switches are thus able to segregate ports into separate VLANs and perform the routing between them.
What layer is MPLS?
layer 2.5MPLS is considered a layer 2.5 networking protocol. Layer 2 carries IP packets over simple LANs or point-to-point WANs, while layer 3 uses internet-wide addressing and routing using IP protocols. MPLS sits in between, with additional features for data transport across the network.
What is the difference between layer 1 and layer 2?
LAYER 1 – The physical layer in the wired world consist of connectors, cables, fiber, and gbics. This is also the layer where data gets transmitted / received into bits, 0’s and 1’s using complex coding and modulations. LAYER 2 – The data layer is where upper layer information (Layers 3-7) is encapsulated into a frame.
Does a firewall have an IP address?
Tip. Firewalls have at least two interfaces. To find the IP address of your firewall’s internal interface, check the default gateway (also known as the default route) on the computers behind the firewall.
Can I ping a switch?
If you are unable to ping a switch from a remote host and you have made sure that your routers have routes to the different subnets in the network, then make sure that you configure the default gateway on your switches for the vlan interfaces, otherwise, you will not be able to ping the switch or have VTY access.
Does Layer 3 switch have IP address?
This is where the Layer-3 switches come in the picture as the technique they use for routing the data packets to the destination is using IP addresses and subnetting. The layer-3 switches work at the 3rd Layer of the OSI reference model and perform the routing of data packets using IP addresses.
How do I ping a switch port?
The easiest way to ping a specific port is to use the telnet command followed by the IP address and the port that you want to ping. You can also specify a domain name instead of an IP address followed by the specific port to be pinged.
