Local management interface exchanges
To maintain the exchanged status information between the frame-relay network and the systems attached to it, use the keep-alive exchange and permanent virtual circuit (PVC) status change.
- Keep-alive exchange
- Use the keep-alive exchange to maintain contact between the terminal equipment (TE) and the frame handler (FH). It consists of an exchange of sequence messages.
At intervals specified by the POLLITV parameter, the TE sends status inquiry messages to the FH. The FH responds with a status message that includes the correct sequence number (both status inquiry and status messages include sequence numbers).
- PVC status change
- After the number of status inquiry messages specified by the FULLINQITV parameter have been completed, the TE requests a full status from the FH. The FH responds with a status message that includes a list of the PVCs assigned to the physical connection and the status of each PVC.
You can use the Display Network Interface Description (DSPNWID) command to show the PVC status reported by the network.
