What is Frame Relay map?
To display the current map entries and information about the connections, use the show frame-relay map EXEC command.
How do you check a Frame Relay?
1. Use the show interfaces serial command to check the state of the interface. 2. If the output shows that the interface is up but the line protocol is down, use the show frame-relay lmi exec command to see which LMI type is configured on the Frame Relay interface.
What is the show Frame Relay LMI?
The show frame-relay lmi privileged EXEC mode command displays LMI statistics of Frame Relay enabled interfaces on the router. Alternatively, the command can be used to display the LMI statistics of a certain interface by specifying the interface type and the interface number.
What is Frame Relay Cisco?
In frame relay, the routers connected to remote networks are usually the DTE devices while the frame relay switch is usually the DCE device. The frame relay switches move data frames from the host networks across the WAN network to the remote DTE devices.
What is the function of the keyword broadcast in the commands?
The interface is enabled for use. BROADCAST. The interface supports broadcasts, which means it is connected to a network that supports broadcasts, such as an Ethernet.
How does a frame relay work?
Frame Relay sends information in packets called frames through a shared Frame Relay network. Each frame contains all the information necessary to route it to the correct destination. So in effect, each endpoint can communicate with many destinations over one access link to the network.
What is a frame relay connection?
Frame relay is a packet-switching telecommunications service designed for cost-efficient data transmission for intermittent traffic between local area networks (LANs) and between endpoints in wide area networks (WANs). The service was once widely available and implemented.
When was Frame Relay introduced?
1990s
At the beginning of the 1990s, Frame Relay service was introduced. While using the same DS0 and fractional or full T1/E1 and T3/E3 connections, by connecting to a “cloud” from a service provider, you no longer needed to purchase and manage individual links between each of the locations that you wanted to connect.
What command will set an IP address for an interface?
The ifconfig command sets, or checks, configuration values for network interfaces. Regardless of the vendor or version of UNIX, the ifconfig command will set the IP address, the subnet mask, and the broadcast address for each interface. Its most basic function is assigning the IP address.
What does route r command do?
route ( r ) – Display and alter the routing table.
Where are frame relays used?
Frame relay is often used to connect LANs with major backbones. It is also used on public WANs and in private network environments with leased T-1 lines. It needs a dedicated connection during transmission and is not ideal for voice or video, which need a steady flow of transmissions.
