Frame Relay Configuration Commands

Event counter. The range of the value is 1~10.

Using the fr lmi n393dte command, you can set N393 parameter at the DTE side.

Using the undo fr lmi n393dte command, you can restore the default

configuration.

By default, the parameter value is 4.

The DTE sends a Status-Enquiry packet at a regular interval to the DCE to inquire

the link status. On receiving this packet, the DCE will immediately send a

Status-Response packet. If the DTE does not receive the response packet in the

specified time, it will record the error by adding 1 to the error count. If the errors

exceed the threshold, the DTE will consider that the physical channels and all the

DLCIs to be unavailable.

N392 and N393 together define the "error threshold". N393 indicates the event

number observed and N392 indicates the error threshold of that number (N393).

That is, if N392 errors occurred in N393 Status-Enquiry packets in the DTE, the DTE

would consider that the error count has exceeded the threshold and declare the

physical channels and all DLCIs to be unavailable.

N392 at DTE side should be less than N393 at DTE side.

For the related commands, see fr interface-type and fr lmi n392dte.

Set the operation of frame relay interface Serial1/0/0 as the DTE mode and sets

N392 to 5 and N393 to 6.
