What is port Type NNI?

A. UNI/NNI is the classification of port types designed for the Metro Ethernet market. UNI, User Network Interface, is the interface that faces the subscriber, and NNI, Network Node Interface, is the interface that faces the service provider network.

What is UNI and NNI?

In telecommunications, a user–network interface (UNI) is a demarcation point between the responsibility of the service provider and the responsibility of the subscriber. This is distinct from a network-to-network interface (NNI) that defines a similar interface between provider networks.

What is the port in Cisco switch?

TE Port. In trunking E port (TE port) mode, an interface functions as a trunking expansion port. It may be connected to another TE port to create an extended ISL (EISL) between two switches. TE ports are specific to Cisco MDS 9000 Family switches.

What are the two types of ports on a switch?

Different Types of Switch Ports

Access Ports. An access port belongs to and carries the traffic of only one VLAN.
Trunk Ports. A trunk port carries the traffic of multiple VLANs and by default is a member of all VLANs in the VLAN database.
Tunnel Ports.

How does an NNI work?

A network-to-network interface (NNI) is a physical interface that connects two or more networks and defines inter signaling and management processes. It enables the linking of networks using signaling, Internet Protocol (IP) or Asynchronous Transfer Mode (ATM) networks.

How does NNI differ from UNI in Frame Relay?

On a UNI interface to Frame Relay, link management procedures occur in one direction. On an NNI interface, link management procedures are bidirectional.

What is the difference between NNI and UNI ports?

A UNI refers to the Ethernet port that is connected to the user equipment which is used for the user-side configuration of the Ethernet service. An NNI refers to the Ethernet port that is connected to the packet transport network which is used for the network-side configuration of the Ethernet service.

What is te port in switch?

On a network switch, the switch port is the physical opening where a data cable can be plugged in. Connecting various devices to the ports on a network switch allows them to interact with each other through data transfer within the switch.

How many ports does a Cisco switch have?

Usually, there are 12 ports PoE Switch in Cisco Compact switch family.

What are the different types of port modes?

A switch port can be in one of two modes: access and trunk. There are two ways a switch port can settle down into one of these two modes: static and dynamic. You can manually configure a switch port to be in the access or trunk mode in the static method.
