What would cause the output of the PVC status to show inactive?

What would cause the output of the PVC status to show inactive?

INACTIVE: State shows a successful connection to the frame Relay switch (DTE to DCE) without the remote DTE detected on the other end of the PVC. This can occur due to incorrect configuration on the switch.

How do you troubleshoot a Frame Relay?

Frame Relay: Frame Relay Link Is Down

1. Use the show interfaces serial command to see whether the interface and line protocol are up.
2. If the interface and line protocol are down, check the cable to make sure that it is a DTE1 serial cable.
3. If the cable is correct, try moving it to a different port.

What is DLCI in Frame Relay?

A data link connection identifier (DLCI) is a Frame Relay 10-bit-wide link-local virtual circuit identifier used to assign frames to a specific PVC or SVC. Frame Relay networks use DLCIs to statistically multiplex frames. DLCIs are preloaded into each switch and act as road signs to the traveling frames.

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 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.

What is discard eligibility De bit?

DE. The Discard Eligibility (DE) bit is set by the end node and, when set and supported by the frame relay network, allows frames to be discarded in preference to other frames when a network is congested.

What is DLCI command?

Using the frame-relay interface-dlci command on main interfaces will enable the use of routing protocols on interfaces that use Inverse ARP. This command is required for all point-to-point subinterfaces; it is also required for multipoint subinterfaces for which dynamic address resolution is enabled.

What does the DLCI number signify?

(Data Link Connection Identifier) The number of a private or switched virtual circuit in a frame relay network. Located in the frame header, the DLCI field identifies which logical circuit the data travels over, and each DLCI has a committed information rate (CIR) associated with it.

How do I enable Frame Relay?

The configuration is pretty simple here and we are just enabling Frame Relay encapsulation using the encapsulation frame-relay command.

1. R1> enable. R1# configure terminal.
2. R2> enable. R2# configure terminal.
3. R3> enable. R3# configure terminal.
4. R1#show frame-relay map.
5. R1#show frame-relay lmi.
6. R1#debug frame-relay lmi.

Is Frame Relay still being used?

The reason you are learning Frame Relay & PPP is to comprehend basic networking principles. Today, these technologies are no longer widely used (although Cisco sells rather a lot of them to people running obsolete but useful/valuable networks).

Is Frame Relay obsolete?

ATM and frame relay are essentially obsolete technologies, although they are still used in some parts of the world that have been slower to upgrade to the latest speeds.
