SERIAL NIM COMMANDS

description <text>

Comment line to provide an identifier for this interface (for example, circuit ID, contact information, etc).

<text> Up to 80 alphanumeric characters

et-clock-source {rxclock | txclock* } Configures the clock source used when creating the external transmit (reference

clock).

rxclock Uses the clock recovered from the receive signal to generate

txclock

ignore dcd

Defines the behavior of the serial interface when the data carrier detect (DCD) signal is lost.

When configured to follow DCD (default condition), the serial interface will not attempt to establish a connection when DCD is not present. When configured to ignore DCD, the serial interface will continue to attempt to establish a connection even when DCD is not present.

invert etclock

Configures the serial NIM to invert the external transmit (reference clock) in the data stream before transmitting.

external transmit clock.

Uses the clock recovered from the transmit signal to generate external transmit clock.

serial mode {V35* | X21}

Configures the electrical mode for the interface. Both modes require the use of the appropriate cable: V.35 (1200873L1) or X.21 (1200874L1).

shutdown

Turns off the interface. The no version of this command turns the interface on and allows it to pass data.

snmp trap

Enables all supported Simple Network Management Protocol (SNMP) traps on the interface.

snmp trap link-status

Controls the SNMP variable to enable (or disable) the interface to send SNMP traps when there is an interface status change.

invert rxclock

Configures the serial interface to expect an inverted receive clock in the received data stream.

invert txclock

Configures the serial interface to invert the transmit clock found in the transmitted data stream.

* Indicates default values.
