How do I change the interface on my Cisco router?
Cisco Networking: Switch Interface Configuration
- Connect to your switch and get into Configuration mode using a set of commands like the following:
- Choose the interface by number.
- Specify the interface number.
What are interfaces on a switch?
With a switch interface, the user can plug the switch into the switch interface and then plug the switch interface into one of the computer ports such as a USB port. Switch interfaces often allow for multiple switches to be plugged in at once.
What different types of interfaces are available on Cisco switches and routers?
Interface Types Supported on Cisco Routers Two types of interfaces are supported: physical and virtual interfaces. The types of physical interfaces on a device depend on its interface processors or port adapters. The virtual interfaces that Cisco routers and access servers support include subinterfaces and IP tunnels.
How do I enable interface on Cisco router?
To enable an interface, it must be activated using the no shutdown command. (This is similar to powering on the interface.) The interface must also be connected to another device (a hub, a switch, or another router) for the physical layer to be active.
What is the status of the port speed LED If the LED light is blinking green?
When selected, the port LEDs will display colors with different meanings. If the LED is off, there is no link, or the port was administratively shut down. If the LED is green, a link is present. If the LED is blinking green, there is activity and the port is sending or receiving data.
Do switches have interfaces?
Interface Configuration Mode The switch supports these interface types: Physical ports—switch ports and routed ports. VLANs—switch virtual interfaces. Port channels—EtherChannel interfaces.
What is the difference between a switch physical interface and the VLAN interface?
What is the difference between a switch’s physical interface and the VLAN interface? A switch’s physical interface is used to physically connect end devices to the network. A switched virtual interface (SVI or VLAN) is used to configure the switch with an IP address so that it can be managed remotely.
What are the two types of router interfaces?
A 100Mbps Ethernet interface is called a “FastEthernet” interface and a 1000Mbps Ethernet interface is called a “GigabitEthernet” interface. Virtual interfaces are also available in a Cisco Router. Examples of virtual interfaces are Loopback interface and Null interface.
How many loopback interfaces can you have on a router?
You can configure up to seven other loopback interfaces ( lo1 , lo2 , lo3 , and so on) on the switch to use to transmit network across the network. Each loopback interface can have multiple IP addresses.
What kind of Cisco switch supports intervlan routing?
Catalyst switch models 3560, 3750, Catalyst 4500/4000 Series with Sup II+ or later, or Catalyst 6500/6000 Series that run Cisco IOS system software support basic InterVLAN routing features in all their supported software versions. Before you attempt this configuration on a 3550 series switch, ensure that you meet these prerequisites:
How are Cisco interface cards used in routers?
This document provides an overview of Cisco interface cards used in Cisco access routers, and contains the following sections: Cisco interface cards are classified according to the technologies they support.
How to configure default route for Cisco switch?
Configure the default route for the switch. From the diagram in the Task section, note that the IP address of the default router is 200.1.1.2. If the switch receives a packet for a network not in the routing table, it forwards it to the default gateway for further processing. From the switch, verify that you can ping the default router.
How to check the status of a Cisco switch?
Show Interface on Cisco Switches On a Layer 2 switch we can check the status and various other counters and metrics for each physical ethernet interface or for every interface on the device. I usually start first with the following command: Switch0# show interfaces status
