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)#
Default
None
Example
XSR(config-if)#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.
