parity
Syntax parity {odd | even | mark | space}
no parity
Context config>port>serial>rs232
config>port>serial>x21
Description This command configures the parity bit in a character. Parity is an error detection method that
adds an extra bit to each character, based on the number of 0s or 1s in the character.
This command is valid only if device-mode is asynchronous. The value for this command
must be no parity (that is, none) if the character-length value is 8 and the stop-bits value is 2.
The no form of this command disables the parity bit in a character.
Default no parity
Parameters odd — the parity bit set to 0 or 1 to make the total number of 1s in the set of bits odd
even — the parity bit set to 0 or 1 to make the total number of 1s in the set of bits even
mark — the parity bit is present but not used and always set to 1
space — the parity bit is present but not used and always set to 0
report-alarm
Syntax [no] report-alarm [hcmOof | hcmRai]
Context config>port>serial>rs232
config>port>serial>x21
Description This command enables logging of HCM alarms for RS-232 and X.21 interfaces. HCM alarms
are not generated for V.35 interfaces because those interfaces do not operate at subrate
speeds.
The no form of this command disables the logging of the specified alarms.
Parameters hcmOof — reports local HCM out-of-frame errors. When configured, hcmOof events are
raised and cleared.
Default HCM out-of-frame alarms are issued
hcmRai — reports remote HCM alarm indications. When configured, hcmRai events are
raised and cleared.
Default HCM alarm indications are issued
