Obtaining Status and Statistical Information

Page 29-45

Physical Layer Information

The statistics shown in this section are taken at the physical, or serial, interface level.

Administrative/Operational Status

This field shows the Administrative and Operational Status of this

WSX

port. The status

indicator before the slash refers to the Administrative Status. If

UP

, then the port has been

enabled and can transmit data as long as its Operational Status is also UP. If the Adminis-
trative Status is

DN

, then the port will not pass data even if its physical connection is

good.

The status indicator after the slash refers to the Operational Status. If UP, then the port is
capable of passing data as long as it has been logically enabled at the Administrative
level. If

DN

, then the port cannot pass data because of a problem in the physical connec-

tion (e.g., cable disconnected, WSX could not detect cable type) or because the port is
Administratively Down.

Speed BPS

The configured speed of the port. For a physical

DTE

port, the actual rate is determined

by the

DCE

device to which the

WSX

is attached (i.e., a modem or

DSU

). For a physical

DCE

port, the actual rate is the rate configured through the

frmodify

command.

Intf Type

The type of cable that is plugged into the

WSX

port. The cable may be

DCE

or

DTE

and

one of 5 different serial types. See Intf Type on page 29-39 for further information.

Receive CRC Errors

The total number of frames with an invalid frame check sequence received on the port
since the last time the switch was initialized.

Receive Aborts

The total number of frames received that were terminated with an

HDLC

abort sequence

since the last time the switch was initialized. An abort sequence consists of 7 contiguous
bits of ones (1111111).

Receive Overruns

The total number of frames that were not received on the port because the system could
not keep up with the data flow. Receive overrun errors include buffer errors and errors
reported by the

RISC

processor.

Transmit Overruns

The total number of frames that were not transmitted on the port because the system
could not keep up with the data flow. Transmit overrun errors include buffer errors and
errors reported by the

RISC

processor.

Signal Errors

The total number of frames that failed to be received or transmitted due to a loss of
modem signals since the last time the switch was initialized. If the

WSX

port is a physical

DTE

, then this count is the number of frames dropped due to a loss of the Data Set Ready

(

DSR

) signal. If the

WSX

port is a physical

DCE

, then this count is the number of frames

dropped due to a loss of the Data Terminal Ready (

DTR

) signal.
