USER’S GUIDE

FRAME RELAY CONNECTIONS

To verify a frame relay connection to the CyberSWITCH, the WAN lines that are connected to the System must be available for use, and the routing option must be properly initialized. To verify a frame relay connection, perform the following:

1.Enter the frame relay stats command at the administration console.

a.If the statistics display appears, the frame relay feature is configured and the frame relay subsystem should be operational.

b.If you receive the message: No Frame Relay Accesses configured, verify your configuration. Refer to Frame Relay Accesses in the Configuring Alternate Accesses chapter.

2.Enter the cs command at the administration console. The device name for the associated PVC should appear in the list of connected sites.

3.Check the report log (dr) for additional messages. If you see any of the following, you may have a problem:

Unexpected error during transmission of LMI frame

[FR_IETF] Authentication Failure of remote device “NAME”

[FR_IETF] Off-node Authentication Failure of remote device “NAME”

Try the following:

a.If the system displays the Unexpected error during transmission of LMI frame message: Use CFGEDIT to change the Frame Relay LMI type. Refer to Configuring General Access Information in the Configuring Alternate Accesses chapter.

b.If the system displays one of the following messages:

[FR_IETF] Authentication Failure of remote device “NAME”

[FR_IETF] Off-node Authentication Failure of remote device “NAME”

It indicates that the device database does not have a device entry corresponding to the per- manent virtual circuit. Use CFGEDIT to change the PVC name to match the remote device name. Refer to Configuring a PVC in the Configuring Alternate Accesses chapter.

PPPLINK FAILURE DETECTION

To verify that Frame Relay’s Link Failure Detection is enabled, perform a trace to view the Echo- Request and Reply packets:

1.With the feature enabled, establish a connection.

2.Erase the system log (er command).

3.Issue the trace ppp on console command.

4.Wait for at least the configured Echo Frequency.
