Hardware Controller Commands

4-88 Configuring Hardware Controllers

parity

This command configures the parity on a serial interface. It is valid and takes effect only when the 
interface is in Asynchronous mode.

Syntax

parity {even | mark | none | odd | space}

Syntax of the “no” Form

The no form of this command invokes the none value:

no parity

Mode

Interface configuration: 

XSR(config-if<Sx>)#

Default

None

Example

XSR(config-if<S1/0>)#parity odd

physical-layer

This command specifies the mode of a serial interface as either synchronous or asynchronous. If 
set to synchronous, the port is configured as a DTE requiring an external transmit and receive clock 
to be supplied. If set to asynchronous, the interface will supply its own clock.

Syntax

physical-layer {sync | async}

even

Even parity.

mark

A constant 1 in the parity bit.

none

No parity.

odd

Odd parity.

space

A constant 0 in the parity bit.

Note: A serial interface configured as a synchronous serial port must have an external transmit and
receive clock.

sync

Synchronous mode of XSR’s serial interface.

async

Asynchronous mode of XSR’s serial interface.
