Note: For SDLC interfaces, the Nt’ interface number is always the same as
the Nt interface number.
CSR Indicates the memory location of the control status register for the SDLC
interface.
Self-test passed
Indicates the total number of times the SDLC interface passed its self-test.
Self-test failed
Indicates the total number of times the SDLC interface was unable pass its
self-test.
Maintenance failed
Indicates the number of maintenance failures.
The following parameters are displayed only if a cable is connected. The
information displayed depends on the cable that is connected. Different parameters
are displayed with other cables.
Adapter cable
Indicates the type of adapter cable that the level converter is using.
V.24circuit
Indicates the circuits being used on the V.24.
Nicknames
Indicates the signals being used on the V.24circuit.
RS-232The EIA 232 (RS 232) circuit names.
State Indicates the state of V.24circuits, signals, and pin assignments (ON or
OFF).
Line speed (configured)
Indicates the currently configured line speed for the SDLC interface.
Last port reset
Indicates how long ago the port was last reset.
Input frame errors
Indicates the input frame error type (CRC error, too short, aborted,
alignment, too long, DMA/FIFO overrun) and the total number of errors that
have occurred.
Output frame counters
Indicates the total number of DMA/FIFO overruns and output aborts sent for
output frames.
Missed frame
When a frame arrives at the device and there is no buffer available, the
hardware drops the frame and increments the missed frame counter.
L & F bits not set
On serial interfaces, the hardware sets input-descriptor information for
arriving frames. If the buffer can accept the complete frame upon arrival,
the hardware sets both the Last and First bits of the frame, indicating that
the buffer accepted the complete frame. If either of the bits is not set, the
packet is dropped, the L & F bits not set counter is incremented, and the
buffer is cleared for reuse.
