If the Line status is upa protocol status of down usually is caused by mismatched data link layer configuration For an example serial interfaces has their combination when one router has configured to use PPPPoint_to_Point Protocol and other remains the default HDLC. Usually the default VLAN 1 acts like the switchs own NIC for connecting into a LAN to send IP packets.

. Configure Switch Ports at the Physical Layer 2122 Just as a network card in a PC can have specific conditions such as duplex and speed set so too can a switch port. If you configure both the interface switch type takes precedence over the global switch type. This parameter must match the provider ISDN switch.

Its a simpler method to configure VPNs it uses a tunnel interface and you dont have to use any pesky access-lists and a crypto-map anymore to define what traffic to encrypt. Configuration Example The loopback interface in this sample configuration is used to support Network Address Translation NAT on the virtual-template interface. The IP address is configured under a logical interface known as the management domain or VLAN.

Hence SPAN is mostly referred to as LOCAL SPAN. For example on switch interface configure an IP address 19202031 and on server interface configure 19202124. SPAN mirrors traffic from one or more interface on the switch to one or more interfaces on the same switch.

Isdn switch-typeConfigures the ISDN switch type. You type in configuration commands and use show commands to get the output from the router or switch. Learn how to configure loopback interfaces on cisco routerIn this tutorial we will learn how to assign ip address on loopback interfacesLoopback interfaces are logical interfaces or you can say virtual interfaces in cisco routerThey are not real interfacesThats why they never goes down untill or unless the complete router itself goes downHere using cisco.

This section examines how to configure specific parameters on a Cisco switch port and introduces auto-MDIX. This configuration example. Up to 64 SPAN destination ports can be configured on a switch.

I use the following topology. ERSPAN is a Cisco proprietary feature. Loopback interfaces should be supported on all Cisco platforms and unlike subinterfaces loopback interfaces are independent of the.

It is always down if the Line status is down. Like our physical interface we assign a special IP address which is called a loopback address or loopback IP address. VLAN Interface is down protocol is down.

Next configure an IP address on the Fa0 interface. Finally point where telnetssh goes to. Perform these steps to configure a loopback interface.

Enter the VLAN 1 configuration mode with the interface vlan 1 global configuration. The CLI is an interface based on text. Ip tftp interface f0.

Protocol Status refers generally two the layer to status. Why the Cisco Routers loopback interface can not be showed up by default. A loopback interface is a virtual interface in our network device that is always up and active after it has been configured.

Lets look at an example. You can enter this parameter in global configuration mode or in interface configuration mode. Make sure the IP address is totally different to the management VLAN of your switch.

Most Cisco devices including routers and switches use a CLI Command Line Interface to configure the network device. Sat Apr 25 150913 2015 version 602U51 interface nve1 source-interface loopback1 member vni 160010 mcast-group 231111 member vni 160020 mcast-group 231111 no shutdown 3172-A show nve internal platform interface detail 3172-A show mac address. For complete information on the loopback commands see the Cisco IOS Release 123 documentation set.

The following is a sample output of the show switch spanning-tree command. This setting is required for both BRI and PRI. Here are the steps to configure an IP address under VLAN 1.

When we configure a destination port its original configuration is overwritten. 3172-A show run interface nve1Command.
